FIELD: machine building.
SUBSTANCE: invention relates to machine building, namely to cesspoolage trucks (for example, KO-505A) heating system, in particular, to tank safety valves heating. Proposed device comprises heat exchangers, which consist of housings, which maintain heat exchangers 3 form, and from combined heat-insulating materials (based on mineral wool, glass wool or foamed rubber), each heat exchanger 3 is connected to exhaust system, via flexible hose 6 and each heat exchanger 3 has solenoid valve 7, which directs exhaust gases flow to atmosphere or into intake hose or is closed. For implementation of condensate drain there is coaxial tank with valve heated by exhaust gases.
EFFECT: technical result is expansion of temperature conditions for cesspoolage truck operation.
