The models in the CU-B series are portable chiller unit (air condensing units) equipped with compressors specifically silenced for external residential environments and for commercial and industrial use.
The series is divided into 2 models: GCU for operating temperatures from 5° to -20° with nominal absorption from 1.1 kW to 40.63 kW and HCU for operating temperatures from -15° to -40° with nominal absorption from 1.13 kW to 25.26 kW.
The range of power covered and the type of construction make the CU-B units extremely versatile elements in terms of composition of an efficient refrigeration system and suitable to meet a wide range of needs.
All models are built around a solid body structure made of sheet steel, equipped with openable doors for quick and effective access to the internal components during maintenance operations.
The particular internal configuration of the CU-B allows the noise level of the system to be reduced: soundproofed compartments house the hermetic compressor which, together with the large-area air-cooled condenser and the 6-pole axial fans with low rotation speed, allow optimal and silent performance to be achieved in operation.
The mini-channel technology condenser includes a dehydrating filter to guarantee punctual and controlled refrigerant operation.
Supplied with pressurized nitrogen, the condenser includes connection pipes with a compressor and a liquid receiver is also supplied.
The receiver includes taps, an alarm light and a safety valve for adjusting and controlling the level of the inflowing and outflowing liquid.
The CU-B models have been equipped with a pressostatic speed variator (in the largest units) and oil pressure switches and minimum and maximum liquid pressure switches that are adjustable and have an automatic reset.
The semi-hermetic compressor(s) mounted on the CU is Bitzer branded and is available in various models for a power range from 0.4 kW to 36.8 kW.
The standard installation involves placing the CU-B units on the ground outside avoiding reductions to the room volume.
Smaller units can be housed on the ceiling or shelf according to the structural needs of the user.
The CU-B units are supplied complete with pre-heating resistance for optimized machine functionality even in difficult climatic conditions.
A practical box with a terminal board installed on the body allows the electrical connection of the CU-B outside, thus avoiding problems of adaptation during installation.
Numerous variants are available in terms of voltage, condensation, refrigeration circuit configuration, electrical panel and type of soundproofing.
