CHA/K/AF 182-P÷604-P

High efficiency air cooled liquid Chillers and Heat Pumps with axial fans, Scroll compressors and plate exchanger

_icona_clint_solo_raffreddamento-riscaldamento_2024.png

The high efficiency liquid Chillers and Heat Pumps of the CHA/K/AF 182-P÷604-P series, with R410A refrigerant, are designed for medium-sized service sector or industrial ambients.
They are used, combined with Fan Coil units, for the air conditioning or heating of the rooms or to remove the heat developed during industrial processes. They can be supplied with Modbus RTU protocol through RS485 serial interface.
Equipped with axial fans, Scroll compressors and plate exchanger, even in the super silent version, these units can be completed by a hydraulic circuit with tank, with pump, with tank and pump.
Are available as option the new EC Inverter fans with high available static pressure and efficiency for indoor ducted installation.

The units are compliant to the ErP Regulation.
On request, units can be supplied with R452B or R454B refrigerant.
