HFC 42 Bar

HFCs are pure gases that leave no oily residues; they have minimal environmental impact and no depleting effect on the ozone layer. HFC227ea and l’HFC125 are over-pressurized with nitrogen to 42 bar. HFC23 saturates the area rapidly, thanks to its natural high vapor tension, with no need of additional propellant gases and no pressure drops during discharge. It is therefore possible to install the cylinders at a considerable distance from the protected area and so reap all the advantages of advanced systems technology.
 
The HFC gases are dielectric, clean, and safe for humans and delicate equipment and precious objects. HFCs extinguish fires partly by physical means, by subtracting thermal energy from the fire, and partly by chemical action, releasing into the space small quantities of substances that scavenge free radicals and inhibit the combustion chain reaction.
 
At design concentrations, HFCs are safe for protecting closed areas and flooding produces only a negligible decrease in the oxygen level. After discharge, the extinguishing agent can be dispersed by simple aeration.
 
HFC extinguishing systems guarantee not only a technically-advanced solution but also savings on space, thanks to the small overall dimensions of the compact system, and on the weight bearing on the structures. These savings continue through the life of the system, making periodic maintenance of the valves and the cylinders easier and less costly.
 
The integrity of any volume protected by a total flooding system must be checked to locate and seal any significant air leaks. Leaks can result in failure to maintain the concentration level of the extinguishing agent for the specified period of time. Verification of leaks must be conducted via the “Door Fan Test.”
