The PistonFire suppressor consists of a pressurized suppressant storage cylinder and a valve body that contains a dust-ignition proof, weatherproof National Electrical Manufacture’s Association (“NEMA”) enclosure. The NEMA enclosure houses the actuating mechanism, pressure switch, pressure gauge, fill valve, OSHA supervisory switch, and field wiring connections.
The E-HRD suppressor is designed for installation on all types of vessels, ducts and pipes for dusts, gases and hybrid mixtures. The suppressor valve is closed with a domed disc and sealing ring and then pressurized with nitrogen.
The HRD dry chemical extinguisher is designed to discharge suppressant in milliseconds to quench an incipient explosion within a process vessel or to block the propagation of flame through interconnected ductwork.
