General Features
RSI range unit coolers have been designed to be installed inside cold rooms suited for fresh and frozen goods storage.
This range has the advantage of having extremely compact dimensions and at the same time gives capacities compact dimensions and at the same time gives capacities comparable to the RC range. This feature allows applications inside cold rooms with a minimum encumbrance in eight.
RSI rang is available in two different fan diameters and two types of fin spacing according to the needed application. Furthermore, the models having 250 mm fan diameter are made with a geometry of 25 x 21.65 and 3/8 tube, where as those having 350 mm fan diameter are made with a geometry of 37.5 x 32.5 and 12 mm tube, The ED version is supplied with mounted defrosting heaters and is suitable for being used at low temperature applications.
Coil
The rang consist of two types of coils, both made of aluminium fins and copper tube: 3/8 tube with a geometry of 25 x 21.65, for models with 250 mm fan diameter; 12 mm tube with a geometry of 37.5 x 32.5, for models with 350 mm fan diameter.
The model types having 250 mm fan diameter are fitted with a coil of 5.3 mm fin spacing, suited for applications with a cold room temperature (Tc) from -30 C to +10 C. The model types having 350 mm fan diameter are made of two different groups: models with 3.5 mm fin spacing suited for cold room temperature (Tc) from -5 C to + 12 C; models with 7 mm fin spacing suited for cold room temperature (Tc) from -35 C to + 4 C. The coil are tested with nitrogen at a pressure of 25 bar.
Fan motor
The fan motor model in use has the following features :
* Manufactured following EN 60 335-1 laws, with internal thermal protection
* Fan diameter 250 mm and 350 mm
* Power supply 230-240V / 1 / 50-60 Hz
* IP 54 protection rate for models with 350 mm fan diameter
* IP 44 protection rate for models with 250 mm fan diameter
* Operating temperature from -40 C to + 40 C
* Electrics made in conformity with 73/23 CEE for low-tension motors
Housing
The housing is made of aluminium. The manufacturing solution used give the housing strength and guarantees
the absence of vibrations during the functioning. Screws, washers and nuts are made of stainless steel.
