The models in the CC-B Multicompressor series are chilled water pump refrigeration units.
These units are equipped with several semi-hermetic compressors in parallel, silenced for industrial use, suitable to meet the requirements of any type of application with working temperatures in the positive, negative and freezing range.
The series is divided into 2 models: GCC for operating temperatures from 0° to -15° with nominal absorption from 11.50 to 146.50 kW and HCC for operating temperatures from -15° to -40° with nominal absorption from 6.90 to 96.20 kW.
All models have been built around a base frame made of pre-painted sheet metal profiles with a soundproofed protective cover with simple ashlar and anti-vibration feet in the sub-frame to avoid movement and noise pollution during machine operation.
The 3 or 4 Bitzer branded compressors are mounted in parallel sharing the delivery and suction manifold and are fixed to the base frame through rubber anti-vibration blocks.
The construction type and the semi-hermetic compressors, available in various models for a power range covered from 6.6 to 120 kW, make the CC-B versatile and safe machines.
Each compressor is also equipped with the relevant taps both in the delivery and the suction phase.
The oil is controlled by a separator and oil equalization connected by a manifold mounted on the compressor lights.
One or two oil level indicators are mounted on the equalization manifold, depending on the number of compressors.
The refrigeration system is completed by liquid receivers that are equipped with a safety valve, a dehydrating filter, a liquid level alarm, a passage light, and shut-off taps.
As a standard feature, with a view to increasing efficiency and safety, the CC-B units are equipped with double minimum and maximum pressure switches for general and emergency use that are adjustable and also have an automatic reset, 3 pressure switches for compressor control in emergency operation, one minimum pressure detection probe, for suction capacity control, and a double maximum and minimum pressure gauge.
There are also two maximum pressure switches that are adjustable and have an automatic reset, for controlling the remote condenser’s fans.
The standard installation involves placing the CC-B units on the ground inside or outside with appropriate protections, avoiding significant reductions to the room volume.
The CC-B units are monitored in operation by means of an electrical panel placed on the side of the body, while the control unit manages all of the settings centrally.
The panel protected by the closing panels includes the disconnector, the power distribution system and the protections for the compressor via motor protection switches.
The supplied panel is IP 55 equipped with a grille and a cooling fan.
The door houses the control unit and the signaling lamps for emergency situations and the locking system of the minimum and maximum pressure switches, completing the profile of a reliable, safe and versatile refrigerating unit thanks to the design and creation of a complete and efficient industrial refrigeration system.
