  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.
