CGD Specifications
Overview
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.
Coil Features
- The CGD range is equipped with highly efficient coils made from aluminum fins and special copper tubes
- Maximum allowable pressure: 80 bar
Casing
Casing Features
Made of a magnesium aluminum alloy, with a smooth finish covered by a plastic protection film
