Water/Glycol Unit Coolers

Features and Applications

Water-Glycol coolers are designed for commercial/industrial cold storage rooms and blast cooling rooms with small, medium, and large cooling capacities.

The Friterm GCS series are coolers that operate with single-direction air discharge, draw-through configuration, and can be ceiling-mounted as standard.

The GCDD series are coolers that operate with double-direction air discharge, blow-through configuration, and are mounted to the ceiling as standard.

Products equipped with three-phase fans, when operated in dual-speed mode, can provide rapid cooling at the initial stage, and then perform a cooling process aimed at reducing product loss with lower air circulation.

The Friterm GCS series consists of 606 models with a capacity range of 0.97 kW – 235 kW with a wide variety of accessory options.

It is suitable to operate with refrigerants such as water, ethylene glycol / propylene glycol, freezium, etc.

Coil Features

Straight tube arrangement that reduces defrost time and defrost energy consumption
Standard fin spacings of 4-7-10-12 mm
Copper / stainless steel (AISI 304) tubes, aluminum fins
Copper / stainless steel (AISI 304) inlet-outlet connections

Casing

Casing made of AlMg3 or magnelis coated steel depending on model and size
Electrostatic powder coated (RAL 9016) casing; smooth, durable, corrosion-resistant decorative structure
Support legs that facilitate transportation and installation of the product (except models with Ø300–350 mm fans)

Drain Pan

Removable drain pan for models with Ø630 mm and larger fan diameters
Hinged drain pan for models with Ø500 mm and smaller fan diameters
Special air-insulated drain pan structure preventing condensation on the outer surface

Fans

High-efficiency axial fans from Ziehl Abegg, EBM or equivalent brands are used in water-glycol coolers
Motor protection class is IP54 for Ø800–630–500–450 mm fans; IP44 for Ø400–350–300 mm fans; insulation class is B and F
Minimum operating temperatures are -25°C for single-phase fans and -40°C for three-phase fans
Special fans should be used for operating conditions below (-40°C)
As standard, 300/350/400/450 mm fans are 230V 1~50 Hz; 500/630/800 mm fans are 400V 3~50Hz
Three-phase fans are dual-speed as standard
Speed control in three-phase fans can be achieved by adding frequency inverter and sine filter
Thermistor connections used for protecting the fan motor must be made
Friterm reserves the right to use different fan brands; depending on this, partial differences may occur in fan information
