The indoor condensing units of the JCR 051÷172 S/K series, with R410A refrigerant, are designed to satisfy the needs of medium-sized domestic or industrial systems with particular difficulty in positioning units outside the building.
These 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 in both air conditioning and industrial process cooling applications
They are equipped with Scroll compressors and radial fans even in a high ESP version, 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.
