90oC high temp Heat Pump
Two-stage cascade compression technology, multi-stage refrigerant heat exchange reduces the compression ratio of the unit operation, greatly improves the low-temperature operation ability and efficiency of the unit, and innovatively realizes the ambient temperature of -35℃ and the outlet water temperature of the unit reaches 90℃, replacing the heating boiler in extremely cold areas.Striking characters distinguishing from other products.
85~90C outlet water temp at -35C.
Both stages adopt industry-leading ultra-low temperature DC inverter and low temperature enhanced vapor injection technology.
Built-in internet WIFI control make the heat pump operation status information to be seen at a glance at thousands of miles away.
Kolant heat pump installation project reference
Kolant solar direct drive Multifunctional heat pump
The heat pump control system can be remotely controlled by mobile APP through cloud server
85C ~ 90C outlet high water temp heat pump with reliable working to replace boiler directly.
Much higher efficiency compared with traditional electric water heater, or gas boiler with same outlet water temp.
EVI technology to enable high performance at low air temp -35C.
Built inside Modbus protocol to enable distributor or customer to use any other controller to control the heat pump.
