FIELD: agriculture, in particular, dairy equipment.
SUBSTANCE: apparatus has reservoir, air-to-water heat-exchanger equipped with fan and spraying device and arranged above reservoir, expansion tank and plate cooler, which are communicated with reservoir. Water circuit change-over device is arranged at plate cooler outlet end and provided with slide. Water circuit change-over device is adapted for communicating plate cooler through pneumatic cylinder with piston to heat-exchanger spraying device. Water circuit change-over device is controlled by means of pulsed pipe through expansion tank serving as sensor and preventing reservoir from water freezing and, accordingly, from breaking down. Expansion tank is equipped with hermetically sealing closure having return valve and vacuum-gauge and is further equipped with scale 17.
EFFECT: enhanced reliability in operation and reduced water loss.
