Air to water EVI heat pump- Extreme low temp -25 celsius degree
DAISHIBA is a professional company engaged in sales, R&D and production of refrigeration and heating products.
We have rich experience in refrigeration and heating for over ten years.
In line with our goal to provide environmental and climate friendly products, DAISHIBA keeps creating more innovative and efficient energy saving products.
By years' growth our product line covers full range Air to water heat pump, Water to water heat pump, Domestic hot water heat pump, Swimming pool heat pump, Air source water circle heat pump, Water to air DC inverter heat pump.
Now we bring our new designed heat pump---Air to water EVI heat pump, which is special for the colder area.
World famous components and muture technology make the high quality products.
Feature:
Delivers higher capacity at low evaporating temperature thereby better responding to heating requirement thanks to EVI compressor
It also results in less supplementary heating to cover the full heating demand on the coldest days.
Workable ambient temperature range - 25°C to 40°C.
Varied heat curve. Controlled water temperature varies according to ambient temperature
Most components are well sealed to retain heat and prevent dripping.

PRODUCTION PROCESS of EVI air to water heat pump
1. Base plates go online
2. Install compressors, condensers and evaporators
3. Assemble and weld copper pipes
4. Recharged with Nitrogen
5. Water-inspection (Check if exist in air leakage)
6. Discharge Nitrogen
7. Vacuum air-removed
8. Add refrigerant
9. Halogen inspection
10. Fix fan component
11. Install electrical control
12. Security checks (Insulation, Ground connection, Dielectric Strength test, Leakage)
13. Run commodity inspection (The noise of components and parts, Function, Timing, shutdown, current, Difference in temperature)
14. Stick nameplate and connection diagram
15. Document attached (Product Manuals, instructions)
16. Final inspection (Appearance parts)
17. Packing
18. Tape-out
