ENERGYPOWER is the range of high efficiency multifunctional units for 4-Pipe systems.
The units CHA/K/EP 182-P÷602-P feature R410A refrigerant and Scroll compressors activated in series based on the requested thermal load, to reach high EER/COP/TER and SEER/SCOP energy values. Thanks to the advanced control system, the units can simultaneously fulfill the heating, cooling and domestic hot water request of the building. The unit can manage the opposed thermal loads at the same time and reach the highest possible efficiency.
Are available as option the axial EC Inverter fans and the new EC Inverter fans with high available static pressure and efficiency for indoor ducted installation.
The units are designed for hot water production up to 55°C.
The units are compliant to the ErP Regulation.
On request, units can be supplied with R452B or R454B refrigerant.
