Sprinkler is the most important part of auto sprinkler fire extinguishing system. The installed sprinklers can detect and extinguish fire automatically. Sprinklers with initiation temperature ranging from 57° C to 182°C can be provided according to the nature of fire risk. Latest design concealed sprinklers can be provided to keep up the aesthetics of places like hotels, banquet halls, supermarkets, offices etc. In case of fire, the sprinkler’s cover automatically drops off when the surrounding temperature is 10°C to 15°C lower than nominal action temperature of the sprinkler head. As the heat increases, the exposed sprinkler sprays water/ chemical to extinguish the fire.
