In 2010 WellFort launched R&D of heat pumps for ultra cold climate. The heat pumps for ultra cold climates are equipped with Copland EVI (Enhanced Vapor Injection) compressors specially and applying superior heat exchange technology. This type of products can be installed in cold weather regions, such as North Europe, North America, and North China. Even if low to -20℃, the heat pumps are able to work normally and reach a COP value of 2.0. Here are some photos of our cases.
We are pretty sure heat pump markets will extend to ultra cold regions, due to this heat pump technology for ultra cold climates.
