Local watermist extinguishing system SPRUT

Local watermist extinguishing system SPRUT

Local watermist extinguishing systems. The systems are based on the principle of lowering the temperature in the fire zone, removing and blocking the supply of oxygen.

What is SPRUT local extinguishing technology?

The principle of water extinguishing is based on the destruction of the "combustion triangle" by cooling the fire site and blocking the flow of oxygen into the chemical reaction zone.
