MHA/K 31÷151

Air cooled condensing units with axial fans and Scroll compressor

The condensing units of the MHA/K 31÷151 series, set up for R410A refrigerant, are designed for small and medium-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. They can also be used in combination with hydronic evaporating units, generally in air conditioning 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.
