CGD Specifications

Range consists of 48 customizable models.

According to the room temperature, the range is divided as follows:

- CGD 3 for high temperatures (≥ 5 °C) with 3 mm fin spacing, designed for work rooms with no possibility of ice/frost formation on fins
- CGD 4 for medium temperatures (≥ +1 °C) with 4 mm fin spacing
- CGD 7 for lower temperatures (≥ –25 °C) with 7 mm fin spacing, electric defrost version (ED) is recommended

On request, the models can be equipped with non-standard: coils, defrosting, and fan motors.

The CGD range is equipped with highly efficient coils made from aluminum fins and special copper tubes
Maximum allowable pressure: 80 bar

Casing Features Made of a magnesium aluminum alloy, with a smooth finish covered by a plastic protection film

The standard AC fan motors employed have the following features:

The optional high efficiency EC fan motors have the following features:

The electric defrost (ED) versions are equipped with stainless steel heaters with vulcanised terminals preset for 400V/3/50-60Hz connections

The versions with standard electric defrost (ED) are equipped with stainless steel heaters with vulcanised terminals preset for 400V/3/50-60 Hz connection
The electric parts and casing are connected to a earth terminal
The wiring of the motors and heaters is carried out in separate IP 54 protection grade junction boxes

Nominal capacity assessed in practical operating ambient, i.e. in wet conditions, in direct expansion application
