MHA-M/K 181÷522
Aircooled condensing units and reversible condensing units with axial fans and Scroll compressors
The condensing units and reversible condensing units of the MHA-M/K 181÷522 series, with R410A refrigerant, are designed for medium and large-sized domestic or industrial systems.
These outdoor units are combined with evaporators in split system air conditioning installations, allowing the rooms to be cooled and dehumidified or to be heated. They can also be used in combination with hydronic evaporating units in both air conditioning and industrial process cooling applications
They are equipped with Scroll compressors and axial fans, and they enable immediate and efficient use thanks to particular technical and design adjustments.
A wide range of accessories, factory fitted or supplied separately, complete the outstanding versatility and functionality of the series.
