GDE Specifications

Overview

The dual discharge GDE range has been specifically designed for cold rooms with limited height for the preservation of fresh or frozen products and in food preparation and handling.

EMEA: Range consist of 48 customizable models
APAC: Range consist of 30 customizable models

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

GDE 3 for higher temperatures (≥ 5 °C) with 3 mm fin spacing, designed for work rooms with no possibility of ice/frost formation on fins
GDE 4 for medium temperatures (≥ 1 °C) with 4 mm fin spacing
GDE 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 entire range is equipped with highly efficient coils made from aluminum fins and inner grooved tube. Thanks to a new geometry there is a substantial reduction of the inner volume resulting in a decreased refrigerant use. The updated coil design responds to the recent guidelines governing the reduction of HFC gases with high greenhouse effect (smooth tube for brine coolers).

Casing

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