FIELD: fire-fighting equipment, particularly means to prevent freezing water store in tank of fire-extinguishing tanker by heat of fuel combustion.
SUBSTANCE: method involves passing-by water under pressure in accordance with "tank-pump-tank" scheme through dispersing cavitation head installed on high-pressure drain connection pipe and feeding water under water layer in tank. Head is formed as replaceable deflector plate spaced a distance of 1-3 outlet head orifice diameter perpendicular to water flow. Outlet head orifice diameter is 25 - 75 mm.
EFFECT: prevention of water freezing and elimination of still spaces in tank under low environment temperature, minimized modification of fire-extinguishing tanker units.
