FOT-Hfc227ea systems are accepted as providing reliable and effective fire protection solutions for high value assets, processes and locations, as well as the people who work in these protected areas

The FOT-Hfc227ea Clean Agent is a colorless, odorless, non-contaminating gaseous fire protection agent. Electrically non-conductive, FM-200 works by removing heat from a fire so that combustion cannot be sustained. The decision to use FOT-Hfc227ea can be based on a number of key factors: it is the most widely used of the chemical replacements for Halon 1301 and it is an agent that has been used to successfully protect tens of thousands of high-technology facilities in 70 countries around the world.

Extensively tested, FOT-Hfc227ea systems are proven safe for use in occupied areas. They are designed using bespoke software, which accurately calculates the amount of FOT-Hfc227ea required for the protected space. The target concentration of FOT-Hfc227ea in an identified protected volume is matched to international standards, which themselves are the result of extensive and repeated fire tests, to match design to fire protection performance..

The FOT-Hfc227ea Hydraulic Flow Clean Agent Fire Suppression System is designed to deliver FOT-Hfc227ea agent.

The FOT-Hfc227ea hydraulic Flow System was developed to be able to locate containers further away from the protected area where flexible designs and longer pipe lengths are required.

The system consists of a super-pressurized FOT-Hfc227ea agent in its container to enhance the discharge of the agent. The additional nitrogen supplied prevents a rapid decline of pressure within the FOT-Hfc227ea container and allows for the FOT-Hfc227ea agent to travel over a longer distance/pipe length..

Key features of the system include:

  • Discharges FOT-Hfc227ea agent in a nominal 10 seconds over distances of more than 100 meters
  • Protection of multiple hazards from a single container location
  • Designed to help protect critical assets and processes
  • Safe to use in occupied areas
  • UL and FM Approved
