PUHZ-SHW112 series heat pumps with patented Zubadan technology

The most advanced technologies for economical and efficient heating and cooling

Thanks to the new technology and high-performance compressor installed, the new PUHZ-SHW has extremely high technical characteristics and is the market leader in terms of seasonal performance and heat output at extremely low ambient temperatures.

These units are designed for heating, domestic hot water and cooling. Unlike all other traditional heat pumps on the market, the MITSUBISHI ELECTRIC units with patented ZUBADAN technology maintain a constant rated output of up to -15 ° C outside temperature, and the manufacturer guarantees cost-effective heat up to -28 ° C outside temperature.

 To ensure safe operation of the heat pump in extreme weather conditions, MITSUBISHI ELECTRIC recommends the use of wind / snow guards. These are special hoods that protect the heat pump’s external device from cold winds, snow and hail, and make it possible to shorten the defrosting time of the unit and extend the operating time between deflections. This reduces power consumption and ensures a longer life time for the heat pump.

The external equipment of PUHZ-SHW112 heat pumps can be equipped with both air-to-air system (industrial SLIM P series) and air-to-water system internal devices (ECODAN tank with integrated boiler EHST20C-YM9C, Hydro-box tank EHSC -YM9C, with heat exchanger CBH60-50 with control interface PAC-IF032B-E or PAC-IF061B-E).

Available Models:

  1. 2018 news! Three-phase, single-fan, extremely quiet outdoor equipment PUHZ-SHW112YAA and PUHZ-SHW8OYAA (air-to-water system only)
  2. Two-fan outdoor equipment PUHZ-SHW112YHA (not only air-to-water, but also air-to-air system can be used).
