Attention

It is important to underscore that the safety measures for use of A2L refrigerants must comply with the provisions of the EN378 standard and the safety data sheets of the fluid used.

AGD

Overview

AGD dual discharge unit coolers for installations that use the latest generation of A2L low GWP refrigerants. This range is specifically designed for limited height rooms used for preservation, preparation and handling of fresh or frozen foodstuffs.
Range consist of 50 customizable models
According to the room temperature the range is divided as follows:

  • AGD 3 for high temperatures (≥ 5 °C) with 3 mm fin spacing, designed for work rooms with no possibility of ice/frost formation on fins;
  • AGD 4 for medium temperatures (≥ +1 °C) with 4 mm fin spacing;
  • AGD 49 for medium temperatures (≥ –15 °C) with 4,5/9 mm staggered fin spacing;
  • AGD 7 for lower temperatures (≥ –25 °C) with 7 mm fin spacing, electric defrost version (ED) is recommended.
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
Casing
Casing Features Made of a magnesium aluminum alloy, with a smooth finish covered by a plastic protection film
Fan Motors
The standard AC fan motors employed have the following features:
  • Ø 230 mm
  • fan motor module: from 1 to 5

  • fibreglass charged polyamide fan guards
    Ø 350 mm: fan motor module: the same as AC fan motors external rotor single phase 230V/1/50-60 Hz fibreglass charged polyamide fan guards speed regulation with 0-10V signal
Defrost
The versions with electric defrost (ED) are equipped with specific stainless steel heaters with vulcanized terminals preset for 230V/1/50-60Hz connection for models with Ø 230 mm, 400V/3/50-60Hz for the models with Ø 315 and Ø 350 mm fan motors
Wiring
The electric parts and casework are connected to a grounding terminal. The wiring of motors and heaters is carried out in separate IP 54 protection grade junction boxes.
