-25 Ambinent Temp Evi Air Source Heat Pump

-25 Ambinent Temp EVI Air source heat pump

EVI Split Heat Pump Product Introduction:

This EVI heat pump is mainly designed for the cold weather area, it comprises indoor unit and outdoor units, which work together to provide hot water 

and heating or cooling function, even under - 25°C low ambient temperature. The water system in the indoor unit, to ensure better anti-freezing and

decrease the heat dissipate. The compressor is available to be built in the outdoor unit or indoor unit. On the other hand, outdoor unit includes nylon

fan and evaporator with thermostatic heating element to prevent frosting.

 

EVI Split Heat Pump Features:

Indoor unit mainly includes condensor, 4-way valve and expansion valve.

1. Avoid the condensor to be burst in the cold weather, better anti-freezing protection

2. High efficient, lower heat dissipate

Outdoor unit comprises evaporator, fan and compressor.

1. Thermostatic heating element for evaporator anti-frosting protection

2. The water connections and the drain pipelines must be protected against frost on site

3. Compressor is outside, to reduce noise mostly inside the house

Auxiliary electronic heater or solar coiler is on your option.

Fashionable design, compact structure, saving space.

Quiet, lower noise when the unit is running.

Advanced control panel. Timer function, automatic defrosting function, optional electrical heating, error messages showed for warning.

It can be working on -25°C low ambient temperature.

Hot water output temperature up to 60°C, for domestic hot water or heating.

Auto-defrosting function included, cooling is optional.

 

EVI Split Heat Pump Main Components:
