The liquid Chillers and Heat Pumps of the CHA/K 726-P÷36012-P series, with R410A refrigerant, are designed for large-sized service sector or industrial ambients.
The units are characterized by multi-compressor design on double cooling circuit, to reach high energy performances, reduction of current at start-up, elimination of inertial tanks and excellent silent functioning. The use of components built in large series makes them highly reliable and the management of a high number of compressors allows increased life span with reduction of machine stopping risks and easier maintenance operations.
Are available as option the new EC Inverter fans with high available static pressure and efficiency.
Cooling only units are compliant to the ErP 2021 Regulation for process cooling application; for comfort cooling application they are compliant if provided with EC or ECH accessory (EC Inverter fans).
Heat pump models 726-P÷13010-P are compliant to the ErP Regulation; models
15010-P÷36012-P are compliant if provided with EC or ECH accessory (EC Inverter fans).
On request, units can be supplied with R452B or R454B refrigerant.
