CGS

CGS Specifications

Overview

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

  • CGS H3 – for higher temperatures (≥ +2 °C), with 3,5/7 mm dual fin spacing and electric defrost
  • CGS H4 – for higher temperatures (≥ +2 °C), with 4 mm fin spacing
  • CGS L4 – for lower temperatures (≥ –25 °C), with 4,5/9 mm dual fin spacing and electric defrost
  • CGS L7 – for lower temperatures (≥ –25 °C), with 7 mm fin spacing and electric defrost

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

Coil Features
  • The CGS range is equipped with highly efficient coils made from aluminium 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
