UNIT DESCRIPTION
This series consists of 9 sizes of water-water heat pumps with heating apacity from 9 to 170 kW.
These units have specifically been projected to work in heat pump, and to produce not only heating but also for sanitary warm water production. The modulating compressor is able to supplier an extremely precise regulation of the water produced according to the demanded requirements.
Both versions are high performance units, in energetic A class.
They satisfy the least values imposed in the enclosure “H” of the buildings decree and they are in accordance of the italian law to obtain the fiscal facilities. The stepless capacity control allows to obtain the maximum efficiency value at the partial load.
Refrigerant is R410A.
