i-ARF 20 - 130
Close control unit free-cooling INVERTER, water cooled direct expansion
19,4 - 133 kW

Description
Ductable close control units air-conditioners for vertical installation and cooling only, with optional heating by means of heating elements and hot water, optional humidifer and dehumidifier for precise temperature and humidity control. Particularly suitable for air conditioning technological, servers and IT rooms and all technological applications in general. Direct expansion FREE-COOLING unit with INVERTER compressor is water cooled and it has to be connected to a remote dry cooler. The INVERTER compressor allows the cooling capacity modulation according to the real internal load, particularly efficient at the partial loads and optimizing the power absorbed and eliminating the start current. Units fitted with electronic expansion valve and EC INVERTER fans, upflow or downflow.
