Low Temperature Air Source Heat Pump with Scroll Compressor

Our low temperature scroll compressor air source heat pump unit is capable of stable operation in temperatures between -25 °C and 35 °C. Drawing energy from the air, the unit functions while emitting no pollution, providing hot water at a temperature of 55 °C to meet any needs between 35 °C and 50 °C. Moreover, the unit comes with a heating feature and is suitable to be used with either direct air supply or floor radiation heating mode.

The module design concept offers versatility, enabling either a single machine or multiple modules to be employed depending on the requirements. This customizable approach is suitable for diverse premises that may have varying cooling and heating loads.
