Fire Suppression Systems

The first line of defense against fire in a commercial kitchen is the fire protection system installed in the exhaust hood. Greenheck has a variety of factory pre-piped fire protection systems available from the two leading manufacturers, Amerex® and Ansul®. Greenheck's fire suppression systems fall under these three categories: Appliance Specific; Full Flood/Overlapping and Dual Agent. All systems use a wet chemical to suppress fire and are a automatic, pre-engineered systems, designed to protect ventilating equipment including hoods, ducts, plenums, filters and cooking equipment.

  • Dual Agent System

    Greenheck uses the Ansul® PIRANHA fire suppression system when dual agent is specified and/or when there is a high chance of fire hazard, such as with doughnut fryers, solid fuel BBQ's or smokers. The Ansul PIRANHA provides a one-two punch against fire by attacking it using the rapid flame knockdown and securing capabilities of PRX™ Liquid Fire Suppressant. Then, the superior cooling effects of water follow, cooling the cooking media below the reflash temperature within two minutes. The water also replenishes the foam blanket so that it can continue act as a suppressant.
