LHi P4 High efficiency air to water multipurpose unit and 4 pipe heat pumps equipped with inverter compressor and axial fans

The LHi P4U/P4S series high-efficiency air-to-water heat pumps are units designed for four-pipe air conditioning and heating systems, which allow the simultaneous or separate production of cold water for cooling and hot water for heating. The units are supplied with an additional exchanger, used as a condenser for hot water, whose production is independent of the unit’s operating mode. The exchanger is automatically activated by microprocessor control when the hot water temperature on the return flow is lower than the set applied. These units are able to produce hot water and cold water simultaneously and/or separately with very high energy efficiency. They are all supplied complete with a specific advanced microprocessor control equipped with software for the management of the various priorities. The XL versions also have an extremely low noise level thanks to the use of a special floating vibration dampening system that allows a noise reduction of about 6-8 dB(A) (optional).
