Clean Agent Automatic & Manuel Automatic Fire Suppression Systems for Pleasure Craft,
Yachts and other Marine & Offshore Environments
The extinguishing agent use in all Marine Fire 740 models is Heptafluoropropane, more commonly known as FE-227. FE-227 rapidly extinguishes fire by cooling the fire to the extent that the combustion reaction cannot sustain itself. It can suppress a fire in 10 seconds or less after discharge. FE-227 does not significantly reduce oxygen levels and is safe for use in occupied spaces in accordance with US EPA guidelines. FE-227 can be removed from the protected space by simply ventilating the space after a system discharge.
It is, non corrosive, and leaves no residue or collateral damage. It has a minimal impact on the environment when compared with that of a major fire or other traditional agents such as Halon: the ozone depletion potential of FE-227 is zero, and it has a reduced estimated atmospheric lifetime.
All cylinders containing from 2 lbs to 40 lbs (1kg to 18kg) of agent are high quality, seamless, lightweight aluminium with epoxy coating designed to hold the FE-227 under pressure until it is discharged.. Cylinders containing more than 40lbs (18kg) of agent are made of high quality steel, designed and built to US DOT 4BW500 and European PED/TPED standards, finishes with an epoxy coating.
All cylinders containing more than 40lbs (18kg) of agent must be installed in the upright position. Each cylinder contains a thermally operated discharge valve, pressure gauge, siphon tube (rigid or semi-rigid according to desired position of cylinder) and pressures witch. All components and valve assembly are brass thus eliminating risk of leakage.
The discharge valve is a thermally operated device; a piston is held in place by an thermally sensitive glass bulb which ruptures upon sensing extreme heat, releasing the piston and releasing agent into the protected space. The system can be activated in either of three different ways:
2) automatically via thermal actuator
3) manual activation and automatic activation together.
