Dry Chemical Systems
Dry chemical fire suppression systems use dry chemical compounds that suppress fire effectively and provide efficient coverage, are easy to install and maintain in any industrial setting. They require recharging after operation. Dry chemical agents come in ABC or BC. In applications where a dedicated water supply is not available, dry chemical is an easy, affordable alternative to water and some other agents.
Dry chemical systems must comply with NFPA 15, Standard for Dry Chemical Extinguishing Systems, and NFPA 33, Standards for Spray Application Using Flammable and Combustible Materials and also tested to the criteria of UL 1254, Standard for Pre-Engineered Dry Chemical Extinguishing System Units.
Wet Chemical Systems
A wet agent system is an effective way for suppressing commercial cooking fires before major damage occurs. When a wet chemical agent is applied in a concentrated liquid spray to a burning surface, it reacts quickly with the cooking media (fats or oils) to produce a foam blanket covering the surface. This reaction, combined with the cooling effect of the wet chemical agent, also reduces the possibility of fire re-flash.
Wet Chemical Systems must comply with the NFPA 17a, Standard for Wet Chemical Extinguishing Systems, and NFPA 96, Standard for Ventilation Control and Fire Protection for Commercial Cooking Operations, and also be tested and listed to ANSI/UL 300 Standard for Fire Testing of Fire Extinguishing Systems for Protection of Commercial Cooking Equipment.
