The flash-injection circuit designed for the VRF CITY MULTI ZUBADAN Y system (a heat pump system for very cold climates) is installed in the latest packaged Hot Water Heat Pump CAHV system.  

By using this advanced injection system and highly efficient compressors, the CAHV packaged system can deliver high-temperature hot water up to 70°C, and ensures fewer losses in terms of performance and capacity at very low outdoor temperatures. 

Mitsubishi Electric has been designing and manufacturing packaged heat pumps for hot water for the commercial sector since 1970.  

The company was one of the first manufacturers in Japan to use heat pump technology to produce hot water, and was also the first to develop a range of solutions operating with R407C, which even then could produce high-temperature hot water up to 70ºC, sufficient to instantly eliminate legionella bacteria.  

Our products are still used today in industrial processes requiring high volumes of high-temperature water.  

Our Hot Water Heat Pump systems are used in hotels, hospitals and care homes, testifying to their superior reliability.  

As a leading manufacturer of domestic hot water production systems, we are proud to introduce the efficient Air to Water packaged heat pump system. 

The CAHV packaged system is capable of operating at outdoor temperatures between -20°C and 40°C, producing high-temperature hot water (65°C) even on the coldest days of the year. In the defrost cycle, the two system compressors operate in turn, limiting the drop in delivery temperature.
