Suoher has a full range of heat pumps, such as On/Off air source heat pumps, DC inverter heat pumps, EVI heat pumps, swimming pool heat pumps, ground source heat pumps, etc. Suoher is one of the earliest manufacturers who research and develop DC inverter heat pumps. Suoher has expanded the models of inverter heat pumps from 5kw, 9kw, 12kw, 15kw to 20kw, 25kw, 35kw and 50kw, so there are more options for the different market demand. Besides, our EVI heat pump which is specially designed for the very cold region and is able to work down to -25°C, wins very good feedback from customers. The EVI heat pump and DC inverter heat pump are our star products in recent years.
