Air-Water Heat pump with AXIAL fans and water-circulation units for Heating and Cooling service industry provided with: inertial storage, circulation pump, hermetic scroll compressor.

 

EH commercial heat pumps range is designed for outdoor installations in commercial applications. This range uses R32 refrigerant which ensures high performances and limited energy consumption. Scroll compressors guarantee high level of efficiency, reliability and minimum noise emission. Air-side exchangers are made up of copper pipes and aluminium fins battery and are supplied with protection grids. Condensation control con-tinuously regulates the fans speed, further reducing the noise emission of the unit at partial loads. Condensation control, combined with the electronic expansion valve, also enables a wide operation range.
