MHI extends Hydrolution EZY series heat pump
30th October 2025
JAPAN: Mitsubishi Heavy Industries has added two new models to its Hydrolution EZY series of R290 air-to-water heat pumps for the European market.
The new monobloc models have capacities of 6kW and 7.1kW and are scheduled for release this winter.
Modifications that allow the use of R290 also enable the units to maintain a flow temperature of 75℃ in a wide range of environments, from an outside temperature of -25℃ to 43℃.
When operating at maximum capacity, the 6kW model is said to have a sound pressure level of just 34dB(A) at 3m. The unit also has a quiet mode for reduced operating noise, providing flexibility to comply with noise regulations in densely populated residential areas.
As a safety measure, the units are equipped with a refrigerant leak detection sensor. In the event of a leak, the unit will stop running, and a fan engaged to dissipate any escaped refrigerant.
The front of the new units are now all-black and fitted with a fan guard accented with a silver vertical line and is designed to make it difficult to see the fan from an oblique direction.
