F-500 EA®
Bladder Tank
Fire Suppression System

Proportion F-500 EA®
Concentrate for Deployment

The F-500 EA® Bladder Tank System is engineered for high-hazard areas in defined spaces. Available in sizes from 136 L (36 G) to 45,425 L (12,000 G), each pressure-rated vessel features an internal bladder storing F-500 EA® concentrate. On activation, water pressure compresses the bladder to deliver a 1%–3% F-500 EA® solution to deluge or sprinkler heads.

F-500 EA®

NFPA 18A-Compliant
Encapsulator Technology

F-500 EA® is an advanced Encapsulator Agent used for fire suppression, vapor mitigation, spill control, and contamination response. Manufactured in the USA at our Georgia headquarters since 1997, this proven technology is now trusted worldwide by firefighters and industry leaders to address Class A, Class B, Class C, Class D, and lithium-ion battery hazards.

What is F-500 EA®?

F-500 EA® is an Encapsulator Agent recognized in NFPA 18A, Standard on Water Additives for Fire Control and Vapor Mitigation. This is the first standard outlining the criteria an agent must meet to be classified as an Encapsulator Agent. The Spherical Micelle Stability Test protocol in Section 7.7 evaluates a concentrate’s ability to form stable spherical micelles which are capable of encapsulating hydrocarbon based fuels, rendering them nonflammable.

Foams work on a mechanical level, relying on a bubble blanket to separate the fuel from the oxygen. Unlike foams, Encapsulator Agents like F-500 EA® work on a molecular level, relying on spherical micelles to encapsulate fuel. These spherical micelles work on all four legs of the fire tetrahedron simultaneously to deliver three unique features: encapsulation, rapid heat reduction, and free radical interruption.

Why should we buy fluorine-free F-500 EA® over fluorine-free foam?

Technology is advancing faster than the codes and standards issued by leading regulatory agencies, leaving firefighters and industry leaders unprepared for the complex challenges of modern fires. In response, many organizations have begun switching to fluorine-free foams in search of a “safer” solution. However, these foams often fall short when faced with high-hazard scenarios.

While fluorine-free foams can be effective in certain situations, NFPA 11 clearly states that foam is not suitable for combating three-dimensional or flowing fuel fires. To provide comprehensive protection across multi-class hazards—including three-dimensional and flowing fuel fires—an alternative solution is required. That solution is fluorine-free F-500 EA®.

F-500 EA® goes beyond traditional fire suppression. In addition to extinguishing modern fires effectively, it actively reduces the concentration of flammable, explosive, and toxic vapors present during an emergency—protecting firefighters, personnel, and civilians in ways that neither foam nor water alone can achieve.

What is a bladder tank unit?

A bladder tank unit is one way to proportion water additives, like NFPA 18A-compliant F-500 EA®, into your water stream to mitigate Class A, Class B, Class C, Class D, and lithium-ion battery fire hazards.

Why should we buy your bladder tank over a competitor’s?

Our complete F-500 EA® Bladder Tank Fire Suppression System offers several unique benefits.

Superior Protection
Make F-500 EA® your fire suppression agent of choice for multi-class and three-dimensional protection against high hazards like lithium-ion batteries.

Eco-friendly Operation
F-500 EA® is a fluorine-free, biodegradable, and noncorrosive agent that delivers effective fire suppression while reducing your environmental impact and costly disposal fees—combining performance with sustainability.

In-house Commissioning
Our engineers deliver a quality assurance process that ensures your fire suppression system is designed, installed, tested, and operating correctly. Rather than outsourcing commissioning to a third-party company, we provide a service led by Encapsulator Technology Specialists.

Do you have examples of previously installed F-500 EA® Bladder Tank Fire Suppression Systems?

Yes!

There are countless F-500 EA® Bladder Tank systems still in service across the globe. Feel free to contact us directly for case studies.

Do you install deluge and sprinkler systems?

We do not install deluge or sprinkler systems. However, our in-house engineering team collaborates closely with project designers and contractors to develop and implement comprehensive fire protection solutions using our bladder tank units and F-500 EA®.
