Variable frequency heat pump unit
The variable frequency heat pump unit is a modern unit which incorporates both a frequency converter and existing unit operations in order to achieve frequency conversion compressor. With this upgrade, its energy efficiency is drastically improved at partial loads, making it a truly transformative double efficient unit capable of reaching full load efficiency (COP) as well as a intergrated part-load value (IPLV).

Electric auxiliary heater
In cold climates where the outdoor heat rating is significantly low, the heating capacity and efficiency of the heat pump can be substantially diminished. To counter this, an auxiliary heat source is advised, making the electric heater the ideal choice.
