evi heat pump (evi air to water, low temp -25 degree, CE)

Goldsun air source heat pump 1. -25 DC low temp use, EVI 2. cooling and heating 3. COP to 4.8, R410a,380V 4. CE approved

Goldsun Air Source Heat Pump For House Heating & Cooling

Goldsun uses the most advanced low Temp Enhanced Vapour Injection compressor technology and  have  successfully 

produced  the EVI low  temperature  heat  pump

Compare to the common series heat pump, you will see below advantages:

1. 43°C ~-25°C wide range use.   EVI air to water heat pump is specially designed for house heating in cold area. The ambient temperature range is -25°C to 43°C. It can use safely in -20°C ambient.

2. Strong low-temperature heating capacity              

Normal heat pump is difficult to heat below -5 degree,  

EVI technology importantly increase refrigerant flow of the main loop and outside evaporation enthalpy difference, brings 7% to 34% 

additional heating.

Reliable Components

1. Hitachi EVI Scroll Compressor

2. Throttle type : Amerson Alco Thermal Expansion Valve

3. Four-way valve: Japan Saglnomiya

4. Extra large evaporator

5. Heat exchanger: Plate type heat exchanger

6. LCD controller

Multi Protection

1. Auto-defrosting function

2. High/low pressure protection

3. Overload protection
