Application and models

Cubic unit coolers, best suited for installation in the ceiling of cold rooms and the cooling of all kind of products. Intersam cubic unit coolers range includes three main different Series for high (ICA), medium (ICM) and low temperatures (ICB).

General features

Coils

High performance finned coils, built in 1/2” grooved copper tube and corrugated aluminium with 3,5; 6 and 8 mm fin spacing. The frame is manufactured in aluminium sheet, protected by collars. They have a Venture type distribution system for the application of thermostatic expansion valves.

External structure

Manufactured in RAL-9018 colour polyester high resistance aluminium. The whole structure is compact and highly rigid to avoid vibrations. All pieces are easily dismantled for maintenance.

Fans

Helicoidal fans with high performance protection grids and 230V / 50Hz singlephase motors (315 and 350mm. diameter) with IP-54 protection grade, external rotor and low power consumption. All the motors can be wired to the centralized waterproof junction box, according to IP-55 standards.

Defrosting heaters

Defrosting is carried out by 230V electric heaters, built in shielded stainless steel tube, with vulcanized ends avoiding shunts, inserted in the coil and tray and wired to the waterproof junction box. All the models may be supplied with defrosting heaters.

Refrigerant capacity

The capacities of the unit coolers are tested in dry atmosphere (sensible heat) according to ENV-328.

The nominal capacities of the catalogue (sensible heat + latent heat) are referred to the tested capacities (SC2) multiplied by a coefficient (latent heat factor) to consider the increasing of capacity (latent heat) due to the condensation of steam water on the unit cooler surface.

This factor depends of the cold room conditions, for high room temperatures is increasing and for low room temperatures is decreasing, as indicated in the attached table  according ENV-328.
