  1. Environmental friendly and safe

Electric parts and water system is completely cut off, ensuring security water use, no pollution to the atmosphere and free of greenhouse effect and it is the safest water heater

  1. Wide climatic zone adaptability

Our heat pumps with special designing possess better climatic adaptability, can work from -25℃ to 43℃.

  1. Energy-saving

Heat pump water heater is a high efficient transferring heating equipment which is driven by electricity. The operating cost is only 1/4 of electric water heater, 1/3 of gas water heater.

  1. Automatic intelligent control system

Adopting intelligent computerized automatic control system, no manual cost, easy to operate, convenient, make heat pump work safely and reliably.

Control panel with modularized unit design can control more flexible heat pumps packs, with user-friendly operating system interface, easy to operate..

  1. Advanced testing methods

Adopting world-class Enthalpy potential laboratory to test heat pumps, except basic testing items, we also test heat pump in the ambient of temperature of -30℃ to test our heat pump performance.

  1. Widely used

Heat pump is applied to hot water for household and commercial use like families, schools, hospitals, shower center, swimming pools, etc. and industrial use like electroplating, drying, etc.

Competitive Advantage:

  1. EVI technology:

Adopting the most advanced low temp Enhanced Vapors Injection compressor technology which can help heat pump work steadily even at temperature of -25℃.

  1. Wide range of temperature:

EVI heat pump can work from -25℃.to 43℃. Widely used in different environment.

3. Higher heating capacity:

Using enlarging evaporator extracting more heat energy from air will increase COP.

  1. Automatic start-up anti-freezing protection

When the ambient is below zero degree, the unit is in standby mode more than 30 minutes, Automatic anti-freezing device will be started up so that the unit will be protecting in lower temperature.

The features of split EVI air source heat pump

  1. Copeland EVI compressor

Adopting world famous brand compressor with perfect application of EVI technology makes

the unit COP arrive at 2.05 even under under -25℃

2.Economizer (Plate heat exchanger)

The Split heat pump with Economizer works more stably under -25℃ and improve efficiency.

3. Split Designing

The split EVI heat pump is with the compressor and the water pipe

both are built in the indoor unit. It ensures less heat loss and perfect anti-freezing protection when the unit is running smoothly under -25℃.


Application of green refrigerant R407C is friendly to the ozone layer,

meanwhile it will improve the efficiency of the units when running.

5.Advanced welding technology

Nitrogen-welding technology purifies the refrigerant pipe system to

avoid the inner residue damages to the compressor; with extra superior

welding flux, it makes welding junction steadier, reduce oxidation of copper pipe,

prevent gas leakage.

6.Aerial material noise isolated sponge

By using high quality aerial noise isolated material, noise

and vibration is avoided perfectly.

7. Outfitting both liquid-storage and gas-liquid separator

Outfitting both liquid-storage and gas liquid separator ensures units run smoothly in different kinds of extreme hostile environment.

8.T6 Fan

Well selected axial T6 fan motor combined with large fan blade, which provide

heavy air blow at low rotate speed, reducing vibration and noise.

9. Eaton (USA) AC contactor and Thermal relay

High quality contactor and thermal relay can freely turn on/off more than 100,000 times.

10. Humanized Control panel design

Military level PCB components, intelligent controlling program reinforced a reliable operation

of the heat pump unit. Special colored wiring design on the PCB provides great convenience in

installation and further maintenance.
