EVI low temp High COP air to water heat Pump

With perfect performance at the ambient temperature as low as -25℃, the units can provide efficient heating for your house and sufficient domestic hot water for your family.

Description

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

2. Wide climatic zone adaptability

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

3. 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.

4. 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..

5. 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.

6. 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. Military level PCB components, intelligent controlling program reinforced a reliable operation of the heat pump unit.
2. Special colored wiring design on the PCB provides great convenience in installation and further maintenance.
3. Nitrogenwelding technology purifies the refrigerant pipe system to avoid the inner residue damages to the compressor;
4. with extra superior welding flux, it makes welding junction steadier, reduce oxidation of copper pipe, prevent gas leakage.
5. Our heat pump outfitting both liquid-storage and gas-liquid separator ensures units run smoothly in different kinds of extreme hostile environment.
6. Well selected axial T6 fan motor combined with large fan blade, which provide heavy air blow at low rotate speed,
7. reducing vibration and noise.
8. High quality contactor and thermal relay can freely turn on/off more than 100,000 times.
