The special formulation of DAVEX® designed for a wide variety of restaurant hazards. It gives enabling very rapid fire knockdown and securement of grease related fires. It provides an excellent cooling effect which further develops its ability to prevent reflash.
DAVEX® Wet Chemical is a specially formulated, aqueous solution of an inorganic salt. The agent is pre-mixed, eliminating the need for dilution before system charging.
DAVEX® Restaurant Fire Suppression Liquids designed for use only in all Restaurant Fire Suppression Systems and K-Class Fire
Extinguishers. This liquid agent will combat grease related fires as found in restaurant appliances and ventilating equipment. It should not be used for fires involving energized electrical hazards.
DAVEX® is principally recommended for protection against fire in :
- Restaurant Fire Suppression Systems
- F Class (EU) & K Class (US) Fire Extinguishers
DAVEX® used in the Restaurant Fire Suppression System or K-Class Fire Extinguishers, extremely effective on fires in restaurant ventilating equipment (hoods and ductwork), in a variety of cooking appliances (deep fat fryers, griddles, range tops, and several types of broilers). Suitable operating temperature is -40°C to 49°C.
As the agent is sprayed in fine droplets onto an appliance grease fire, it provides excellent fire knock down, surface cooling, and fire securing capabilities. When the DAVEX® reacts with the hot grease, it initially forms a
layer of foam on the surface of the grease. This blanket of foam acts as an insulator between the hot grease and the atmosphere, helping to prevent flammable vapors from escaping and reducing the chance for flame reignition.
Post-fire cleanup can be readily accomplished by flushing the area with water or steam. Because of the composition of DAVEX®, it is compatible with metals commonly found in restaurant kitchen area (stainless steel, aluminum, galvanized metal, mild steel, copper and brass).
