Explosion Suppressors

An explosion suppression system consists of three components: a (i) detector; (ii) control unit; and (iii) suppressor(s). In the event an ignition occurs, the fireball expands from the ignition kernel with the pressure wave (created by the increase in temperature) traveling ahead of the flame front. Explosion pressure detectors are configured to respond to the characteristic pressure increase within milliseconds.


PistonFire Suppressor


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.


E-HRD Suppressor


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.


HRD Dry Chemical Extinguisher


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.


PHRD Suppressor


These suppressors are used for explosion suppression of gases, solvent vapours and combustible dusts.
