Reimagining the fire hose with HEN Nozzles

Sunny Sethi, founder of HEN Nozzles, discusses the evolution of fire suppression tools shaped by science and firefighter feedback for today’s challenges

In the face of increasingly complex and devastating fires, one engineer is working to bring firefighting equipment into the modern age.

Sunny Sethi, founder of HEN Nozzles, started his company in 2020 after witnessing the destructive wildfires that ravaged California.

Realising that firefighters were battling these blazes with outdated tools, Sethi set out to develop equipment designed for today’s challenges.

“I started HEN after seeing the impact of wildfires on communities,” says Sethi.

“When I spoke with firefighters, it became clear that while the nature of fires has changed, the equipment used to combat them has not kept pace.”

HEN Nozzles has recently secured $8 million in funding to fast-track its cutting-edge fluidics technology, capable of extinguishing fires 300% faster while using 67% less water.

This seed round, supported by federal grants, venture capital, and angel investors, will fuel the development and deployment of HEN’s revolutionary fire suppression tools.

Supported by funding from the National Science Foundation, HEN Nozzles has focused on understanding the science behind fire suppression.

By studying how water interacts with fire, the company has developed new nozzle technology aimed at enhancing the efficiency of firefighting efforts.

Redesigning the fire hose nozzle

Traditional fire hose nozzles often produce water streams that lose effectiveness before reaching the core of a fire.

“Water can break into small droplets that are carried away by the wind,” Sethi notes.

“Even when it reaches the flames, it might not absorb enough heat before falling to the ground.”

Through computer simulations and extensive research, HEN Nozzles identified optimal droplet sizes, velocities, and stream geometries to maximise heat absorption.

The result is a patented blade nozzle that generates a water stream with larger droplets, extended reach, and an adjustable pattern.

“This design allows firefighters to extinguish fires more quickly using less water,” says Sethi.

“It helps them manage situations more effectively while reducing environmental harm and property damage.”

Collaboration and feedback from firefighters

Input from active-duty firefighters has been central in developing HEN’s products.

“We work closely with those on the front lines,” Sethi emphasises.

“Features like the adjustable stream patterns came directly from their feedback.”

Ray McCormack, a former lieutenant with 39 years of service in the New York Fire Department, has been an advisor to HEN Nozzles.

“Firefighters know what they need,” McCormack says. “HEN listens to us, and that shows in their designs.”

Adjustments such as refining the nozzle’s handling to reduce fatigue during prolonged operations were made based on user input.

McCormack points out that even the shut-off handle was designed to provide a comfortable grip while fitting into existing hose beds.

“HEN’s products are shaped by the people who use them,” McCormack adds. “That makes a real difference.”

Testing, certification, and meeting diverse needs

To ensure safety and effectiveness, HEN Nozzles conducts extensive testing.

“We’ve carried out live fire burns in training centres and acquired houses,” Sethi explains. “We use thermal cameras to analyse performance and collect data.”

All HEN nozzles meet standards set by the National Fire Protection Association (NFPA) 1964 for spray nozzles and appliances.

“Our research is backed by the National Science Foundation, which adds credibility to our work,” says Sethi.

The products undergo mechanical and thermal tests to ensure they meet durability standards.

“Firefighters rely on their equipment in critical situations,” Sethi notes. “We have to be certain our tools will perform under pressure.”

HEN Nozzles aims to serve both wildland and urban fire departments. “We offer combination smoothbore nozzles with different flow rates,” Sethi says.

“Firefighters can adjust the pattern based on the situation they face.”

In wildland settings, the blade pattern creates a concentrated linear stream, allowing for quicker coverage of larger areas.

In structural fires, the pattern helps cool surfaces and gases, leading to faster suppression.

“Our goal is to provide tools that adapt to different environments,” Sethi explains.

“Firefighters encounter a variety of challenges, and their equipment should be versatile.”

McCormack adds: “All HEN nozzles are designed with firefighter input from the beginning.

The compact design and reduced weight came from their recommendations.”

Expanding reach and addressing environmental concerns

HEN Nozzles’ clients include organisations such as CAL FIRE, the U.S. Marine Corps, and several fire departments across the country, including those in Kansas City, Ontario, Maui, and Sacramento.

“These partnerships have been essential in refining our products,” Sethi notes. “We aim to reach an additional 1,000 departments in 2025.”

The recent funding will enable HEN Nozzles to accelerate development and production.

“We plan to expand our team, invest in further research, and increase manufacturing capacity,” says Sethi.

Water conservation is a significant issue, especially in regions prone to drought.

“By increasing suppression rates, we use less water,” Sethi points out.

“This conserves resources and lessens the environmental harm of firefighting operations.”

Quicker suppression also means fewer emissions from prolonged firefighting efforts. “Reducing the duration of fires benefits everyone,” Sethi says.

Challenges and looking ahead

Progress in firefighting tools has been slow, partly due to reliance on established systems.

McCormack believes that the environment in which firefighters operate has changed, and equipment needs to reflect that.

“Firefighters are using systems that aren’t as efficient as they could be,” McCormack says.

“Manufacturers haven’t always recognised the need to change. HEN is responding with technology that brings more efficiency.”

Sethi acknowledges that introducing new tools requires demonstrating clear benefits.

“Firefighters need to trust that new equipment will help them do their jobs better and more safely,” he says.

“We focus on providing evidence through testing and feedback.”

Sethi’s journey began with witnessing the devastation of wildfires in California.

“I saw how communities were affected,” he recalls. “It was clear that something needed to change.”

By combining scientific research with practical feedback from firefighters, Sethi hopes to make a meaningful contribution to the field.

“Our mission is to provide tools that help firefighters meet the challenges they face today,” he says.

With the support of the firefighting community and new funding, HEN Nozzles is planning for the future.

“We’re committed to continuous improvement,” Sethi says. “There’s always more to learn and ways to make our products better.”

McCormack shares this optimism. “HEN’s approach is making a difference,” he says.

“Their technology brings efficiency that can benefit firefighters everywhere.”

As HEN Nozzles moves forward, the focus remains on supporting those who protect communities from fires.

“It’s about making their work safer and more effective,” Sethi concludes. “That’s what drives us.”

Engineering precision: Ed Barnes discusses Reacton Fire Suppression’s commitment to quality, accessibility, and innovation in fire suppression solutions

Reacton Fire Suppression’s Chief Technical Officer, Ed Barnes, shares insights into their metrology lab, international plans and engineering for accessible, high-quality fire suppression solutions

With an emphasis on innovation and quality, Ed Barnes, Chief Technical Officer at Reacton Fire Suppression, has been on a journey in engineering that his developed a commitment to delivering precision-driven, accessible fire suppression solutions.

Reacton’s state-of-the-art metrology lab ensures world-class product standards, positioning the company as a leader in the fire and safety sector.

As the industry gears up for Intersec 2025, Barnes offers insights into Reacton’s global strategy, including their ambitious plans for the EMEA region and beyond.

Can you tell me about Reacton’s metrology lab and its impact on product quality?

The metrology lab is a specialised facility for precise measurement and quality control, providing capabilities that many competitors and subcontracting engineering companies lack due to insufficient scientific tools.

To control quality to an exceptional standard, we needed the same measurement tools used in making our parts—measuring dimensions, surfaces and other physical aspects of them daily.

The metrology lab enables us to measure and control the goods we receive and those we make or machine in-house.

It’s also a diagnostics tool for finding items that may need adjusting.

If you make mechanical parts, it’s your diagnostics laboratory.

We’ve invested about a quarter of a million pounds in measurement and quality control equipment.

This allows us to build a stable understanding of the parts we receive and make.

Over time, it enables us to detect problems like dimension creep.

The equipment has enabled our team to learn and develop themselves.

They’ve learned more from measuring and monitoring than from making the parts.

We measure with micron accuracy—a micron is one-thousandth of a millimetre.

Knowing precisely what something is allows the team to make good decisions about what to do with that part.

How does the metrology lab ensure precision and reliability across Reacton’s products?

Everything we receive and make is measured precisely against every drawing.

We’re not just talking about dimensions but also measuring things like surface finish, which is crucial for seals.

If you need to keep gas in a cylinder, you need to know how the seal performs over time.

We’ve introduced helium leak detection equipment at multiple levels, which complements the metrology lab.

It allows us to measure gas leakage rates precisely. We can determine if a leak will take a day to drain a volume or 120 years.

This means every product that leaves our factory has been precisely tested and diagnosed to the standard we intended.

We’re not just assembling something and assuming it works over time; we’ve got exact numbers for days, months, years, or leak rates that meet our tolerances.

Having the equipment to diagnose what we’ve made ensures we maintain high precision and reliability across our product range.

How does the lab drive innovation in Reacton’s fire suppression systems?

The metrology lab allows us to control our tolerances more precisely.

By measuring everything accurately, we can reduce our tolerances, leading to better-performing products.

The team learns more from measuring and monitoring, which contributes to innovation.

We can detect issues early, make adjustments and improve designs based on precise data.

Having the metrology lab and equipment like helium leak detectors enables us to experiment and develop new products with confidence.

We can simulate how parts will perform, measure outcomes and iterate on designs efficiently.

This accelerates innovation in our design and development process.

How do you provide precision-engineered solutions to cost-sensitive markets worldwide?

The key is the standardisation of products.

Our concepts and intellectual property are based on common items.

Where other businesses might use different products for different markets—like vehicle fires, control panels, kitchens, or CNC machines—we use the same products across applications.

This allows us to focus our engineering control around these products.

Instead of making multiple different valves, we make one main common valve.

This means we can centre our manufacturing around one product, honing the quality and producing in volume.

Hoses, valves, nozzles, fittings and bracketry are all common components that have undergone multiple revisions.

By simplifying and standardising our components, we can purchase in larger quantities, reduce stock and maintain high quality, making our solutions accessible even in cost-sensitive markets.

We machine about 150 components in-house now, up from not making anything internally two years ago.

We brought in the metrology lab and CNC machines not to save money but to control what we make.

The variations of standard products means that we already deeply understand how the core product works.

How does the metrology lab help adapt products for diverse EMEA market requirements?

Different markets have different requirements, like pressure directives for cylinders or specific valve functions.

However, we still use common components.

The valve may undergo changes for different markets, but 90% of it remains the same as the one we originally engineered.

When adapting to a market, we don’t start from scratch; we look for the shortest path without creating an entirely new product range.

The metrology lab allows us to ensure that any adaptations meet necessary standards and regulations.

We can measure and test components to ensure they comply with regional requirements while maintaining our high-quality standards.

Most necessary adaptations have been made, so our product can be sold anywhere and meet all requirements.

How do the lab’s capabilities align with Reacton’s goals for accessible, reliable solutions?

The metrology lab’s capabilities are central to our focus on precision and accessibility.

By measuring and controlling every aspect of our products precisely, we ensure they are reliable and perform as intended.

This precision allows us to innovate confidently, knowing we can test and validate new designs effectively.

The lab also supports our goal of accessibility by enabling us to standardise components and produce them efficiently.

By controlling the quality and consistency of our products, we can offer high-quality solutions at competitive prices, making them accessible to a wider range of customers.

What recent successes or innovations stand out as impactful for both Reacton and the wider industry?

Our detection side has seen a major overhaul with new electronic components that complement the system.

We’ve refined our manufacturing processes internally, equipping our team with more tools to produce products to an even higher standard in less time.

There have been many improvements in lean manufacturing.

We’ve made significant upgrades to our system to meet traceability and quality requirements for industries like transport and military, securing future contracts in those areas.

We’ve introduced a simulation suite to simulate vibration, flow, stress, temperature and wear before producing parts, which is particularly useful for special projects with unknown variables.

Any final thoughts?

In safety engineering, you can come up with wonderful ideas to keep people safe, but if they’re impractical or expensive, they won’t be adopted.

The adoption of safety equipment depends on its feasibility. If protecting every bus costs too much, it won’t happen.

But if it’s affordable, it will. That’s where value engineering comes in.

You can create unbelievable products with broad applications by building a standard set of components honed over years.

If you’re going to do something, you do it to the best possible standard, with the best value engineering and repeatability in quality.

My career has been about identifying how we can do things better and finding ways to improve.

That comes from designing well, manufacturing to the highest standard and providing exceptional customer support.

Engineering is disruptive because you learn through failure and embracing failure is essential.

The passion for quality is crucial. It leads to finding and working with the right customers.

If your distributors and customers don’t share the same passion for quality, then you’re not in the right place.

Driving the passion for quality brings the right customers.

We use our own products in the UK; all our CNC machines use the systems we sell worldwide.

We’ve had incidents on our machines where the system has done what it’s supposed to do.

The passion for quality is the headline. For me, quality drives the right behaviours in business almost all of the time.

CAFS technology for modern firefighting, with Esteri Group

Esteri Group explains how its CAFS 2500’s advanced foam delivery system reduces water consumption and improves fire suppression

Firefighting is evolving. As new challenges arise, so too does the need for innovative, efficient, and adaptable tools.

Esteri CAFS 2500, the latest innovation from Esteri Group, marks a significant advancement in firefighting technology.

This system combines the proven reliability of Esteri® fire pumps with the modern efficiency of a compressed air foam system (CAFS). Designed with precision and versatility, the Esteri CAFS 2500 is engineered to meet and exceed the demands of contemporary fire services – a highlight of Intersec 2025.

Compressed air foam systems (CAFS) is a paradigm shift in fire suppression and has transformed modern firefighting strategies. By combining water, foam concentrate, and compressed air, these systems create foam that adheres to surfaces, cools faster, and suppresses fires more effectively than traditional water-based suppression methods.

The CAFS system utilises compressed air produced by a compressor, allowing the foam to be generated within the system itself—essentially, the foam is created directly at the fire truck’s pump. This method ensures the production of efficient and consistent fire suppression foam.

The Esteri CAFS 2500 takes this proven concept to new heights, introducing advanced engineering to ensure superior performance. By using significantly less water and foam concentrate, it enhances operational efficiency while reducing environmental impact.

Esteri CAFS 2500 delivers adjustable foam ratios ranging from wet foam (1:3) to dry foam (1:10). It delivers unparalleled flexibility across various fire types, including structural, industrial, and wildfires. The result? Faster extinguishment, reduced water consumption, and superior environmental performance.

This efficiency also makes it an exeptional operational advantage in regions where water resources may be limited.

Advanced features

Esteri CAFS 2500 introduces a range of highly developed features that excel in rescue operations while providing users with ease of use.

High foam delivery and efficiency

Delivering up to 2500 litres per minute, the Esteri CAFS 2500 is designed to suppress even the largest fires rapidly. Its powerful 18.5 kW compressor generates 2800 litres of compressed air per minute, ensuring consistent foam production. This level of performance translates to faster knockdowns, reduced water damage, and improved firefighter safety.

Precision engineering for adjustable foam ratios

The ability to adjust foam ratios allows fire services to tailor suppression strategies based on fire behaviour and environmental conditions. Wet foam ratios are ideal for immediate knockdown, while dry foam is optimal for creating barriers to contain fires.

Ease of use in high-stress environments

The Esteri CAFS 2500 is designed with user convenience at its core. Its control panel, available as a touchscreen or with physical buttons, simplifies operation by allowing firefighters to adjust foam output, pressure settings, and other parameters with ease. This intuitive interface ensures optimal performance and reliability, even in the most high-pressure scenarios, catering to diverse user preferences and operational demands.

Compact and space-saving design

One of the Esteri CAFS 2500’s standout features is its integrated design. By combining the pump and CAFS into a single unit, it optimises space, making it ideal for firefighting vehicles. Despite its compact footprint, the system is robust, durable, and easy to maintain.

Durability and reliability

The system’s IP-65-rated control panel protects against water and dust, ensuring reliability in rugged firefighting conditions. Built on Esteri’s trusted fire pump technology, the CAFS 2500 is designed for durability under extreme conditions.

Environmentally friendly and cost-effective

The Esteri CAFS 2500 significantly reduces water and foam concentrate usage. Its eco-friendly design minimises the environmental impact of firefighting operations while lowering costs associated with water transport and foam usage. For instance, the fluorine-free Class A foam mixture requires only a 0.3% concentration, aligning with global sustainability goals.

Applications across firefighting scenarios

While water has been the traditional agent for fire suppression, it is not always effective—especially for oil fires, where its use can be hazardous. Fire suppression with foam is not a new concept. In 1902, Russian engineer Aleksandr Loran revolutionised fire suppression by inventing (patented in 1924) firefighting foam, initially used to combat persistent oil fires. Since then, foam has been a vital tool in scenarios where water alone is insufficient.

The Esteri CAFS 2500 builds on this legacy with applications in:

  • Structural Fires: Wet foam extinguishes flames rapidly, while dry foam prevents reignition by creating barriers.
  • Industrial Fires: The system’s high foam delivery and strong adhesion are particularly effective in industrial settings, where rapid suppression can prevent catastrophic damage.
  • Wildfires: As wildfires increase globally, CAFS offers a critical solution. Dry foam blankets vegetation to prevent fire spread, using minimal water.

Different and demanding fire scenarios require a lot from firefighting equipment. The mobility of CAFS foam within hoses enables operations over extensive ranges. With foam output of approximately 2100–2300 l/min through a 75mm attack line, the horizontal reach is around 500 meters, maintaining foam efficiency and quality.

Vertically, the system achieves a reach of approximately 80 meters. Additionally, it can be configured for high-rise operations, further enhancing its utility.

Sustainability in firefighting

Modern firefighting goes beyond performance—it demands sustainability. The Esteri CAFS 2500 addresses this with:

  • Optimised water usage: Reduced water consumption lowers the strain on resources and minimises runoff of contaminated water.
  • Minimal foam concentrate consumption: Fluorine-free foams, used at a mixture rate as low as 0.3%, are both efficient and safer for the environment.
  • Energy efficiency: The system’s compressor is designed for minimal energy consumption, aligning with global sustainability goals.

While foam-based suppression has its challenges, including environmental concerns, its unparalleled effectiveness ensures its continued relevance. Foam manufacturers are dedicated to developing cleaner solutions, ensuring CAFS remains a vital tool in firefighting; There are scenarios where foam-based firefighting remains indispensable.

Design philosophy and maintenance

The Esteri CAFS 2500 is built around the Esteri® fire pump, resulting in a compact, space-saving solution. Key components, including the compressor, foam pump, mixing pipe, and control unit, are designed for durability and straightforward maintenance. This ensures minimal downtime and maximised operational readiness. All CAFS components can also be installed separately into the vehicle’s piping system.

The system’s clean, intuitive design reflects its purpose. Streamlined yet rugged, it symbolises efficiency and resilience, making it a reliable partner in demanding firefighting scenarios. As a visually striking piece of technology, the Esteri CAFS 2500 also underscores Esteri Group’s commitment to quality and innovation.

From innovation to installation with Piping Logistics

Jeroen De Smedt, CEO of Piping Logistics, discusses the company’s R&D initiatives, expansion into HVAC, and its sustainable production facility in Romania

In a relatively short time, the specialised manufacturer Piping Logistics has established itself as an innovative, client-focused leader in the fire protection sector.

With a new production facility in Romania, the development of new components, and expansion into the HVAC market, the Belgian company clearly proves its commitment to fire safety.

Profit, an aggregation of ‘Professional’ and ‘Fittings’, is the brand name of the Piping Logistics group, specialising in producing and supplying high-quality components for fire protection systems and HVAC installations.

For almost 20 years, the family business has operated from Aalst, where its central location ensures efficient delivery to customers throughout Europe.

Impressive but organic growth trajectory

Contractors and installers recognise in Piping Logistics a reliable partner for a wide range of products, such as pipes, fittings, couplings and accessories, essential for the installation of sprinkler and HVAC systems.

The components are designed for maximum safety and efficiency.

‘We invest extensively in modern production technologies and strict quality controls,’ says CEO Jeroen De Smedt.

The company’s growth has been impressive and, above all, organic.

“In the beginning, the company primarily distributed components sourced from China, an opportunity that founder André Saelens realised while running AquaSecurity, a fire protection installation company.

“Over the years, Piping Logistics expanded by establishing an in-house R&D department, a dedicated marketing team, and a production facility for our own components.”, says De Smedt.

AquaSecurity is still active, allowing it to act as a test lab for Piping Logistics’ innovations.

The CEO adds: “Without a doubt, a strong USP for our product development.

Yet another unique selling point is that Piping Logistics is committed to being on site within 24 hours in case of any issues, anywhere in the world.”

But the engineers are doing more and are also bending over the components coming from China, ensuring they meet the strict European standards.

“It’s about improving the usability, conforming to customer expectations, but also aligning the products to legal requirements. It is an important part of our strive for quality,’ De Smedt says.

Prefab systems as a new addition

Thanks to an ultra-wide range, Piping Logistics can position itself as a one-stop shop.

“We started as a supplier of couplings and fittings but have since developed a full product range. We can offer installers practically the complete package for a sprinkler installation.

“Only the sprinkler head is not yet in our range. We are actively working on it,” says the CEO.

Expansion into HVAC

It’s only a small step from sprinkler systems to accessories for HVAC.

Because the same couplings and fittings fit both water pipe systems.

“The main difference is water temperature and working pressure, but we have undertaken all the necessary tests and approvals to take our products to the huge potential of the HVAC market,” says Jeroen De Smedt.

Furthermore, Piping Logistics counts on its large stock for providing optimal customer service.

De Smedt said: “In Belgium, we have a 6.000 m² warehouse. Such a large stock is necessary for impeccable service.

“If a customer orders before noon, delivery takes place the next day. We can move faster than the competition.”

But even an SME has to grow if it wants to stay healthy.

That is why Piping Logistics has just opened a brand new factory in Romania.

“Within the context of the European Green Deal and the impending CO2 tax, it’s important to produce closer to home. Customers are also starting to wake up to this,” the CEO outlines.

In Romania, Piping Logistics produces prefab sprinkler pipes.

“That new product aims to save time, with outlets for the sprinkler heads pre-welded in the right place. On site, the installer just has to screw in the sprinkler head,” De Smedt concludes.

Exclusive interview with CEO Piping Logistics CEO Jeroen De Smedt

We pride ourselves on offering custom solutions tailored to the unique needs of each client’s project while also delivering standardised models that meet rigorous international certifications, such as FM Approvals.

Proportioning innovation

The FIREMIKS proportioning system operates on the principle of positive displacement for both the water motor and the concentrate pump. The water motor, driven solely by the extinguishing water flow, powers the concentrate pump, which injects the concentrate into the water flow. The dosing is determined by the volumetric relationship between the water motor and the concentrate pump. This ratio is unaffected by viscosity, within specified limits as outlined in the unit’s data sheet.

“The dosing is determined by the volumetric relationship between the water motor and the concentrate pump.”

Per Aredal, International Sales Director at Firemiks AB

The volumetric water motor design, conceived by the grandfather of the current management in the late 1970s, is notably compact for the flow it can handle. For example, on a typical 3% unit, the water motor can process approximately 30 times the volume of the concentrate pump, yet its size remains only slightly larger.

Since its inception, we have continuously refined the design to enhance performance and reliability. As with any pump design, attention to detail and precise execution are key. Additionally, our system’s flexibility allows us to quickly adapt and match the water motor with a wide range of high-end concentrate pumps, each with its own unique specifications to consider.

Customised systems

We offer a wide range of models to meet various flow capacities and proportioning needs. Our smallest model has a maximum flow rate of 150 liters per minute (lpm), while the largest single model can handle up to 10,000 lpm. For flows exceeding this, we provide parallel-installed FIREMIKS systems, either on a base skid or as “double-decker” units, capable of reaching up to 20,000 lpm.

Our three standard skid models include: 12,000 lpm (2 x 6,000 lpm), 16,000 lpm (2 x 8,000 lpm) and 20,000 lpm (2 x 10,000 lpm). For fixed proportioning, we typically offer 1% and 3%, with the option to customise dosing rates such as 0.1%, 0.3%, 2%, or 6% upon request. Additionally, models with selectable proportioning are available, including combinations like 0.3-0.6-1% and 1-2-3%, or, for selected flow sizes, 0.5-1-3%.

Ensuring accuracy

FM approval designates our system as the “Variable Viscosity Pump Proportioner,” meaning that as long as the specified minimum and maximum flow rates in the data sheet are followed, FIREMIKS can accommodate viscosity changes across a wide flow and pressure range. The dosing remains within the approved tolerance limits specified in the standards (e.g., 3.0-3.9%). This offers the significant advantage of eliminating the need for recalibration whenever there is a change in concentrate or viscosity—unlike bladder tanks, which often require recalibration and create critical downtime during replacement.

The FM approval we have received (Standard: 5130 – May 2021) for eight of our 3% models, across three flow sizes—1800, 2400 and 4000 lpm—confirms that the FM-approved FIREMIKS units provide accurate dosing and can handle concentrates ranging from 1 cP to high-viscosity concentrates (up to 6422 cP at a shear rate of 5 1/s).

The specific curve approved for our FM-approved models is as follows:

Shear rate 1/sViscosity (cP)
56422
103545
201945
50882
100497
600128

This means that if a concentrate has a shear rate curve that aligns with or falls below the specified figures, it will perform well with our FM-approved FIREMIKS models. This applies even to the new generation of fluorine-free SFFF concentrates, which are often non-Newtonian.

To ensure optimal dosing performance at maximum viscosity for the three FM-approved sizes, the required concentrate delivery hose/pipe dimensions and height are as follows: a maximum length of 2.5 meters, a diameter of DN 65 or larger and a gravity feed height of 0.5 meters or higher.

Addressing regulatory shifts

Regulatory bodies are driving the transition from PFAS-containing concentrates to SFFF concentrates, prompting a re-evaluation of many proportioning systems for compatibility. Manufacturers offer SFFF foams with a broad range of viscosities, including very high-viscosity concentrates. To select the right proportioner, understanding the concentrate’s properties is essential.

“With the new SFFF concentrates, which are often non-Newtonian, accurately predicting flow behaviour has become more complex.”

Per Aredal, International Sales Director at Firemiks AB

In the past, engineers could calculate concentrate flow with confidence, but with the new SFFF concentrates, which are often non-Newtonian, accurately predicting flow behaviour has become more complex.

For proportioners that require calibration, the dosing may be accurate under specific conditions, but even small changes in variables can cause the system to fall out of calibration. In such cases, it’s better to rely on a system, like FIREMIKS, that is designed to handle a wide viscosity range without the need for recalibration.

Catering to all viscosities

FIREMIKS distinguishes itself by offering two types of dosing pumps—Piston and Gear pumps—coupled with a robust multi-vane motor, built on over 35 years of market experience. When working with clients, we prioritise understanding the concentrate type and viscosity, in addition to considering flow and pressure, before recommending the most suitable pump type and providing tailored installation advice.

It’s important to note that all Piston pump systems on the market have a viscosity limit due to the reciprocating principle of the Piston pump. During each revolution, the plunger sucks in concentrate and then presses it out, causing the concentrate to go from zero to full speed twice per revolution. If the static viscosity of non-Newtonian concentrates is too high, the concentrate may not flow smoothly, resulting in an inaccurate dosing rate.

Our Piston pump models typically excel in systems with low start-up flows relative to their maximum flow rate, making them ideal for applications like sprinkler systems and offering versatility across a wide flow range.

On the other hand, our Gear pump units are highly effective for handling high-viscosity fluids. Their counter-rotating gears create a consistent, non-agitating flow, ensuring reliable sealing with such fluids. Gear pump models are also particularly efficient in applications operating at the higher end of the maximum flow rate, such as deluge and large fire monitor systems.

What’s next for firefighting foam?

The ongoing market shift from AFFF (Aqueous Film Forming Foam) to SFFF (Synthetic Fluorine-Free Foam) concentrates, which is expected to continue for at least the next 10 years, presents challenges for both existing and new foam systems. This transition will drive the need to upgrade many current systems. We are also seeing increased interest in lower dosing rates, such as 1% and even lower concentrations like 0.3% or 0.5%. Additionally, developing effective systems for extinguishing Li-Ion battery fires remains a significant challenge for the entire firefighting industry. Firemiks AB is well-positioned to support this shift and is prepared to further develop our systems as needed to meet varying concentration requirements.

From Auxquimia to Perimeter Solutions: Fifty years of safety success

Javier Castro, VP and General Manager of Fire Safety EMEA at Perimeter Solutions, reflects on Auxquimia’s 50-year journey from family business to global firefighting solution leader

Staying in business long-term is no small feat. In fact, data show that roughly 20% of new businesses in Spain fail within their first year.

This makes the success of Auxquimia, based in Mieres, Asturias, Spain, all the more impressive.

Founded as a family business by the Acuña family in 1974, Auxquimia celebrates its 50th anniversary this year, reflecting on its remarkable evolution into one of the global leaders in firefighting foam concentrates.

When the company first opened its doors, it started as an engineering firm and provided consulting services for its customers.

Later, it became one of the first companies in Spain to manufacture industrial consumer products primarily for the safety sector.

These early products brought Auxquimia into the fire safety industry.

Based on resin foams, these solutions were designed to prevent and combat fires in the mining industry, particularly in coal mines.

Expanding safety solutions for a changing industry

Building on its firefighting foam capabilities, Auxquimia expanded its fire safety portfolio by developing fire extinguisher additives, high-expansion foam concentrates, aqueous film-forming foams (like AUXQUIMIA® AQUAFILM™) and alcohol resistant-AFFF solutions, (such as AUXQUIMIA® Polyfoam.

As the company continued to grow, their portfolio of firefighting foam concentrate solutions advanced.

Responding to industry concerns surrounding polyfluoroalkyl substances (PFAS), the company began developing fluorine-free solutions that were used to battle fires involving flammable liquids, such as petroleum and kerosene.

The industry responded positively to Auxquimia’s advanced technology and the company began a concentrated effort to expand its business to international markets.

They started exporting from Spain to other European countries, including France, Finland, Italy and the United Kingdom, as well as countries in South America and Asia.

With a strong commitment to innovation and an experienced research and development team, Auxquimia was seen as a leader in the international fire safety industry.

The proven effectiveness of its products and its large production capacity led it to becoming the sole supplier of firefighting foam concentrates to major global companies in multiple industries including the petrochemical, chemical, naval, aerospace, energy, mining and automotive segments.

A new era: Strategic acquisitions and global expansion

Around this time, the fire safety division of Israel Chemicals Limited (now Perimeter Solutions, as of 2018) sought to expand its wildfire business into other segments of the fire safety industry, including industrial fire safety.

ICL owned the PHOS-CHEK® brand of fire retardant and firefighting foams and maintained production facilities in the United States, Canada and France.

On May 2, 2014, they completed the acquisition of Auxquimia, expanding its portfolio of Class B firefighting foams.

In a statement released at the time, ICL said the purchase completed the organisation’s goal to become the main supplier for firefighters around the world.

Following the acquisition, Auxquimia continued to work to reduce the environmental impact of its products and they made a commitment to further develop firefighting foam concentrates that were free of fluorine.

In 2015, Auxquimia was exporting nearly three-quarters of its manufactured products to locations throughout Europe, Asia and America, while securing partnerships with major customers.

In 2018, SK Capital acquired ICL’s oil additives and firefighting business units, which included Auxquimia and formed Perimeter Solutions.

The newly formed independent company now specialised in fire management chemicals, oil and lubricant additives and chemicals for pesticide and mining applications.

Bolstering global production

Later that year, Perimeter Solutions made a key acquisition to expand its firefighting foam business when it bought The Solberg Company, the firefighting foam products division of Amerex Corporation.

At the time of the acquisition, Solberg maintained production facilities in the United States, Australia and Norway and Perimeter Solutions made the decision to transfer Norway’s production to Asturias, Spain, to merge that location’s firefighting foam operations with Auxquimia into a single unit.

In 2021, Auxquimia’s focus on developing more environmentally responsible solutions led to the introduction of SOLBERG® VERSAGARD™ AS-100 Multi-Purpose 3×3 Fluorine-Free Foam Concentrate, an alcohol-resistant, state-of-the-art pseudoplastic foam technology that contains no intentionally added PFAS chemicals that can be used to secure Class B (hydrocarbon fuel and polar solvent fuel) fires and deep-seated Class A fires.

This biodegradable and non-persistent fluorine-free foam concentrate became an instantly viable alternative to traditional fluorinated AR-AFFF 3×3 products that were on the market.

SOLBERG VERSAGARD AS-100 delivers excellent firefighting performance, but one of its key advantages when compared to other fluorine-free solutions on the market, is the consistent viscosity it maintains when in contact with water, dramatically improving handling and use rates in firefighting operations.

Auxquimia expanded the SOLBERG VERSAGARD line a year later with SOLBERG® VERSAGARD™ 1×3.

Ideal for industrial emergency response, its low viscosity has made it the firefighting foam of choice for organisations in the petrochemical space.

Haitham Khouri, CEO of Perimeter Solutions, joined the Auxquimia team on September 16, 2024, to celebrate the company’s 50th Anniversary.

One of the original founders of Auxquimia was in attendance and was honored with a plaque for his part in building the organisation.

Representatives from local and regional authorities, valued collaborators, employees and friends also joined to mark the milestone.

A legacy of leadership

Looking back over its 50 years of innovation, Auxquimia has developed a stellar line of proprietary firefighting solutions in addition to its SOLBERG VERSAGARD products, including:

  • AUXQUIMIA® AQUAFILM™: Aqueous Film Forming Foam (AFFF) for fighting hydrocarbon fires.
  • AUXQUIMIA® AUXIFOAM: Synthetic resin for fire extinguishing.
  • AUXQUIMIA® FLUOPOL™: Synthetic fluorine-free foams, free of fluorosurfactants, containing polysaccharides that give the foam a pseudoplastic behavior, providing slow drainage and fluoropolymers for good oleophobicity.
  • AUXQUIMIA® POLYFOAM 3/3: Versatile synthetic AFFF for fighting hydrocarbon and polar solvent fires (alcohols, ketones, ethers, esters, amines, etc.).
  • AUXQUIMIA® UNIPOL-FF™: Synthetic foam based on hydrocarbon surfactants. It does not contain fluorinated surfactants or polymers. It can be used in the extinguishing of both Class B (liquids) and Class A (solids) fires.

As Auxquimia celebrates its 50th anniversary, it stands at the forefront of innovation in firefighting technology.

The company’s commitment to developing high-performance, more environmentally responsible solutions has solidified its role as a global leader in fire safety.

Looking ahead, Auxquimia is poised to continue shaping the future of the industry by pushing the boundaries of foam concentrate technology, ensuring that its products not only meet the rigorous demands of modern firefighting but continue to be one of the leaders in innovation.

With its experienced team, cutting-edge research and continued investment in sustainability, Auxquimia is well-positioned to lead the charge in the next generation of firefighting solutions—ensuring that it remains a trusted partner in saving lives and protecting property for many decades to come.
