D Type Fire Extinguisher Used For?
Suitable for metal industries, refineries, laboratories, machining operations and other locations with combustible-metal hazards.
PYRO Based Powder
TEC Type Fire Extinguisher uses a specially formulated powder agent based on a mixture of three metal chlorides: Sodium, Potassium, and Barium. Conforming to world class manufacturing quality standards, it is ideal for fighting light metal fires in the range of 500-2000 °C. It can also be used in an effective fight against small oil fires.
PYRO Based Powder
The PYRO powder melts and fuses at ~1200°C, making it extremely efficient against alkali metal fires, as well as metal fires such as plutonium, titanium, lead, copper, tungsten, cobalt, and manganese.
