The models in the CU-W Twin scroll digital series are fast chiller mini-units/air-cooled condensing units equipped with compressors that have been specifically silenced for external residential environments and for commercial and industrial use.
The series includes the GCU model for operating temperatures from 5° to -20° with nominal absorption from 4.74 kW to 10.35 kW.
The construction type and the wide power range covered make the Twin mini-units versatile and safe machines in terms of our solution for an efficient refrigerating system which is suitable to meet a wide range of needs.
All models have been built around a compact body in steel sheet whose particular internal configuration allows the noise level during operation to be reduced: soundproofed compartments house the 2 scroll hermetic compressors that together with the large-area air condenser and the 6-pole axial fans with low rotation speed ensure optimal and silenced performance.
The mini-channel technology condenser includes a dehydrating filter to guarantee punctual and controlled refrigerant operation.
Supplied with pressurized nitrogen, the condensing unit includes connections with a compressor and receiver for liquid as 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-W Twin scroll models are equipped with minimum and maximum pressure switches that are adjustable and have an automatic reset.
The 2 hermetic scroll compressors in parallel, one of which is digital for continuous capacity modulation in average and low temperature refrigeration applications, are offered in various models for a power range covered from 4.4 kW to 12 kW.
The standard installation involves placing the CU-W units on the ground outside avoiding reductions to the room volume.
Ceiling installation is also possible depending on the structural needs of the user.
The CU-W Twin scroll digital units are supplied complete with pre-heating resistance for optimized machine functionality even in difficult climatic conditions to which the mini-unit could be exposed.
The machine includes an electronic control unit for controlling the power of the compressors to guarantee a constantly adequate operation by the unit.
The electrical panel with thermal-magnetic protection devices for possible energy overload situations and the emergency system for compressor control complete the standard equipment of an efficient, safe and widely customizable condensing unit.
Numerous variants are available in terms of voltage, condensation, refrigeration circuit configuration, electrical panel and type of soundproofing.
