This one is our commercial KK series of air to water commercial heat pumps.

  Commercial KK series are designed for offering heat to bigger houses, or commercial buildings, such as office, workshop, super market, school, etc.

  Commercial KK is equipped with big evaporator, testing in lower operating temperature, and higher COP in practical working condition.

  Vertical air flow with strong blower, better efficiency and lower noise. Unique "V" style evaporator design is big strongpoint for this unit.

  It increased the condenser space in air flow direction, which results bigger effective air volume. It had been proved to be better efficiency by our testing. This design is also easier for the defrosting water to drain out.

  Scroll compressor with R410a refrigerant is standard for this series. It is helpful to get better performance in low temperature.

  Standard unit composition:

  1) Base frame and external panels made of galvanized powder coated steel.

  2) Extremely compact structure, easy demountable for access.

  3) Vertical air flow with "V" style evaporator refrigerant.

  4) Reverse cycle valve.

  5) Wilo water pump.

  6) Flow switch for water flow protection.

  7) Intelligent controller and adjustment by quickmind microprocessor.

  8) New lattice LCD display wire controller, with touch screen.

  9) Water side equipped with EST high efficiency exchanger.

  10) Air exchanger (Fins-coil) with hydrophilic coating.

  11) Automatic defrosting function included.

  12) Thermostatic heating element for evaporator anti-frosting protection.

  13) Thermostatic expansion valve.

  14) General testing and operational test carried out for every unit before package in the factory.

  Optional:

  1) Energy recovery exchanger equipped inside, for producing sanitary hot water.

  2) Stainless steel case for option.

  3) Additional water storage tank.
