Home Use Cold Climate Heat Pump Systems / Powerful Air Exchange Heat Pump
Cold Climate Heat Pump Systems Features
● Efficient and Energy-saving
Air source heat pumps absorb hot energy from the air freely, and the electricity is only used to drive the compressor to pump up the heat from the air. So, it consumes just a quarter of traditional electric heaters, saving a lot of electric costs for users.
● Green and Environmental Protection
By using air hot energy and electric energy, there is no harmful gas being discharged during the operation of heat pumps. R407C refrigerant guarantees fluoride-free emission.
● Usable All-weather
All weather operation: stable operation without being influenced by any windy, rainy or snowy weather.
● Endurable
The Enhanced Vapor Injection (EVI) technology from Copeland compressor with crankcase heater for special cold area, Danfoss electronic expansion valve, Eaton AC contactor and thermal relay and other brand components of the heat pump guarantee high quality and a long lifespan. All of our screws and clips (both external and internal) are stainless steel. The cabinets we are using are made of GALVANIZED STEEL, making them more rust resistant, durable and affordable.
