Mobile dry powder fireextinguishers are effective on all types of fire - Class A, B, C. Our drypowder agents - monoammonium phosphate and ammonium sulphate base - arenon-conductors of electricity. When discharged, the heat from the fire isgreatly reduced. Firstly, because a cloud of powder provides an effectiveheat-shield. Secondly, because there is an immediate knockdown of the flames.Hence, the flames are suffocated and any embers are extinguished by a layer ofmelted powder
