3 phase DC inverter heat pump-23KW-HOT!
Enjoy big capacity heat pump with lower working current 15 Amp China Palm expand more on DC inverter heat pump technology and become the 1st factory in China to produce 3 phase DC inverter heat pump 23kw 3phase DC Inverter air source Heat Pump with Heating and Cooling and domestic hot water functions,  Working current is reduced to 15 Amp. 3 phase DC inverter control is almost trible complicated than 1 phase DC inverter control as it need to transfer the 3 phase to DC current and run the compressor. Now you can enjoy the lower working current together with the inverter advantage. With most advance European technology to work well in Minus -25ºC much more Higer efficiency than normal air source heat pump. Main Characters: 1. Much more higher COP than normal DC inverter heat pump 2.  Installation is easy and flexible.. 3.  Can be connected with solar water heater system. 4.  All water access parts are stainless steel to keep safe, healthy and non-pollution  Quality for reliability and save maintenance cost:   Our parts are always choosend with the top brand in the world Heat exchanger: SWEP brand plate heat exchanger from Sweden. Heat expansion valve: Emerson brand Four way valve: Saginomiya brand of Japan The above parts enable our heat pump to be trouble free products.
