PAH VS High efficiency air to water heat pumps equipped with inverter screw compressors and axial fan

Packaged air cooled heat pumps of PAH VS Ke series are suitable for outdoor installation and can be used to cool and heat fluid solutions for air conditioning or in industrial applications. The SEMI-HERMETIC SCREW compressor technology with INVERTER motor control, constantly modulating, guarantees a high capacity of partialisation of the cooling and heating power supplied, with a consequent increase in seasonal efficiency, also in applications with highly variable loads. All the units are totally factory assembled and tested, following specific quality procedures. Besides they are totally hydraulic, cooling and electrical connected permitting a quick installation once on site. Before the test the cooling circuits of each unit are subjected to a pressure test and then charged with Refrigerant R513A and non-freezing oil.
