What is HFC 125 fire suppression system?
HFC-125 suppresses fire by absorbing heat energy at its molecular level faster than the heat can be generated, so the fire cannot sustain itself. It also forms free radicals to chemically interfere with the chain reaction of the combustion process.
What is the difference between FM-200 and Novec?
The two types of systems differ when it comes to their impact on the environment. Both agents cause no ozone depletion, either. FM200 has a global warming potential of around 3500, while Novec 1230 has a global warming potential of 1, making it the environmentally-friendly choice.
Is FM-200 an ozone depletion?
It is estimated that FM200® has achieved approximately 80% of the worldwide market for the replacement of halon in fire fighting systems15. It was developed as a non ozone depleting replacement for halon 1301. FM200® easily protects most hazards that were traditionally protected by halon 1301.
What is the atmospheric lifetime of FM-200?
While FM-200 has zero ozone depletion potential it has a short atmospheric lifetime of 33 years giving it a Global Warming Potential. FM-200 systems are designed to extinguish fires and most fires are extinguished within 60 seconds.
Is Novec 1230 the same as FM200?
Novec™ 1230 is an FM-200™ alternative and is one of the leading clean agent fire suppression agents. It works similarly to FM-200™ in that it removes heat from the fire to rapidly suppress it.
Is Novec 1230 an HFC?
3M™ Novec™ 1230 Fire Protection Fluid is a clean agent fire extinguishant which was developed as a halon replacement and hydrofluorocarbon (HFC) alternative. It belongs to a family of chemicals called halocarbons, a group which includes HFCs and fluoroketones.
Which gas is used in FM 200 system?
FM200 (HFC 227ea) is known chemically as Heptafluoropropane. FM200 is a colourless gas which is liquified under pressure for storage. Like Halon 1301 it has a low toxicity level and is superpressurised with Nitrogen to 24.8bar (360psi).
What does FM-200 stand for?
heptafluoropropane
FM200 is the commercial name given to it by its makers, DuPont. Its technical name is ‘heptafluoropropane’ and it is a colourless, odourless halocarbon.
What is the difference between FM 200 and S 125 systems?
For most common hazards NAF S 125 systems require 20% less agent than FM 200 systems. The fire suppressant plays an important role in the overall cost of halocarbon systems.
Can FM-200™ be used as a fire starter?
FM-200™ is designed to be held as a liquified compressed gas in the bottle/cylinder, once discharged through to the pipework and nozzles, it will change state to vapor due to its low boiling point, where it will absorb heat from the space. As a fire requires 3 things to start, Fuel, Oxygen & heat, removing the heat will restrict it from starting.
How does NAF S 125 work?
Like Halon 1301 (- 57 °C), when dispersed through the nozzle/s into an enclosure at normal temperatures NAF S 125 vaporizes very quickly and creates a homogenous mix of air and agent throughout the enclosure. Faster distribution means faster extinguishment.
What is the difference between HFC-227 EA and ECARO-25?
Fike’s ECARO-25 clean agent fire protection system requires 20% less clean agent per cubic foot/meter than HFC-227 ea or FM-200® fire suppression systems and an incredible 38% less clean agent than FK-5-1-12 – that’s a significant cost savings.
