PYROCHEMThe PYRO-CHEM KITCHEN KNIGHT II Pre-Engineered System utilizes a wet chemical agent specifically designed to suppress restaurant cooking area fires. The system provides automatic actuation and can be manually actuated through a remote mechanical pull station. Upon actuation, the system discharges a pre-determined amount of agent to the duct, plenum, and cooking appliances. The agent acts to suppress fires in three ways:
1-The chemical chain reaction causing combustion is interrupted by both the agent itself and the resulting steam formation.
2-The agent cools the fire bringing it below auto-ignition temperature.
3-The agent reacts with hot grease forming a soap-like layer (saponification) that helps prevent the escape of combustible vapors, thus preventing re-ignition.The shutdown of all sources of fuel and electric power that produce heat to all equipment protected by the system is required upon system actuation. Make up or supply air fans, Integral to the exhaust hood(s) being protected shall be shut down upon system actuation. Exhaust fan(s) in the ventilation system should remain on during system discharge as They assist the dispersion of chemical through the ventilating system. The system is UL Listed with or without exhaust fan shutdown.
