i-AD 29-130

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. DUAL FLUID unit has to be connected to an external chiller for PRIMARY circuit. The direct expansion circuit with INVERTER compressor, secondary or BACK-UP circuit, is air cooled and has to be connected with a remote condenser. 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.

Features

Unit for installing inside or outside the room to be air-conditioned.Maximum resistance to rust thanks to galvanised sheet metal structures and panels with powder-coated paint finish. The panels are lined with sound-insulating material to limit noise levels. The reliability and functionality of the compressor and all the other parts are guaranteed by partners who are world leaders in their sector.NEW EC INVERTER fans with electronic commutation in order to maximize the energy saving and reducing the noise emissions.Condensing control for maximum low noise (optional).Standard G2/G4 filtering section, F6-F8 optional, to CEN-EN 779 with average degree of separation 90.1% ASHRAE. The filter is self-extinguishing.

The microprocessor controls the compressor activation times with FIFO logic, thereby regulating the cooling capacity; it also controls the operating alarms with the possibility of interfacing to supervisor and remote-servicing systems.

Switchboard to IEC 204-1/EN60204-1

Refrigerant circuit consisting in the standard version of a electronic expansion valve, liquid solenoid valve, high/low pressure switch, sight glass liquid indicator, drier filter and oil separator in order to guarantee the right lubrification of the compressor at the low speed.
