Working environment

Applicable to -25~45- the outdoor harsh environment temperature, all-weather work.

 

EVI compressor

Low-temperature Enhanced Vapour Injection ( EVI ) compressor is equipped inside to get better high efficiency heat transfer. It  helps the heat pump reach a good performance in cold climate.

 

Ecological and economical heating

The most efficient and economical alternative to both fossil fuel boilers and air conditioning systems.

Efficiency up to 4 times more than conventional systems.

By 1 kilowatt of electricity Axen heat pump produces 3 to 4 kilowatts of heat.

 

By making use of the renewable source in the outside air, it consumes much less energy without direct CO2 emission. Since 60 to 80% of the heat produced by Axen heat pump system is from air(renewable source)it reduces carbon emission. It is the alternative choice for a new boiler installation.

 

Easy installation at low cost:

Axen heat pump generates heat by taking energy from the air. No digging or excavation works are required. The outdoor unit can be placed easily outside building or apartments.  The indoor unit could be installed in the room easily.

 

Safe use:

Axen heat pump works without oil, gas or other hazardous substance which avoid potential risk. Moreover no gas connection or a fuel tank is needed. No risk of intoxication, smell or pollution from leakage.
