AIRCOOLED 4-PIPE MULTIFUNCTIONAL UNITS WITH AXIAL FANS, SCROLL COMPRESSORS AND PLATE EXCHANGERS
ENERGYPOWER is the range of high efficiency multifunctional units for 4-Pipe systems.
The units CHA/K/EP 604-P÷2004-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. The units are characterized by double cooling circuit. 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. ENERGYPOWER units make the traditional layout of the technical plants easier because the production of thermal energy for the several users are joint in one unit only; the result is an advantage in terms of installation, maintenance and management and in the meantime of the comfort needs.
Are available as option the axial EC Inverter fans and the new EC Inverter fans with high available static pressure.
The units are designed for hot water production up to 55°C.
The models 604-P÷1404-P are compliant to ErP Regulations. The models 1604-P÷2004-P are compliant to ErP 2021 Regulations for comfort cooling application if provided with EC or ECH accessory (EC Inverter fans).
On request, units can be supplied with R452B or R454B refrigerant.
