    Heat pumps are constructed using the principle of heat transfer of ambient air energy to heat the water flowing through the heat exchanger, consumed in the farm or the engineering systems of buildings, through the reverse cycle of the operation of the refrigeration machine (heat pump).

    The assortment of this product consists of models of different heat output, and one device allows to provide water heating in volumes from 0.3 to 1 m³ of water per hour (with a maximum heating temperature of up to 60 ° C and an allowable range of outside air temperatures from -10 to +40 ° C At the same time, the coefficient of COP is the ratio of the amount of thermal energy produced to the consumed electric energy, in this series of products it reaches 4, which makes it possible to draw a conclusion about the high energy efficiency and tangible economic effect of such systems in The context of energy conservation policies and the use of "non-traditional" renewable sources of thermal energy.

    Commercial series of heat pumps designed for use in administrative and public buildings, as an alternative to gas or electric water heating systems for hot water.

    Strapping elements, vibration mounts, control panels (for 380 models) are not included in the delivery set. The units are designed to heat water in storage tanks.

    The units can be combined in a modular manner into a common circuit (for one storage tank) up to 16 units.
