Refrigeration racks equipped with several compressors.

The CC-B series models are refrigeration racks equipped with several Bitzer compressors connected in parallel, suitable to satisfy the demands of any type of application with positive and negative working temperatures.

The series is divided into 3 product lines. One line with working temperatures from 0°C to -10°, one line working with temperatures from -30°C to -40°C and one line working with temperature from +10°C to 0°C.

All the units are assembled starting from a solid pre painted steel sheets frame with soundproofed protection cover and anti vibration supports that prevent possible vibrations of the unit during operation.

The compressors (3 or 4) are connected in parallel with one suction and discharge header and are fixed to the frame by means of rubber anti vibration supports that prevent possible vibrations of the unit during operation.

Each compressor is also equipped with the relevant taps both in the delivery and the suction phase.

The oil management system is by means of oil separator and oil equalization through a header fitted on the compressor oil sight glass.

The refrigeration system is completed by liquid receivers, equipped with a safety valve, a dehydrating filter, a liquid level alarm, a passage light, and shut-off taps.

As standard equipment and to increase efficiency and safety of this CC-B series, the units are equipped with adjustable minimum and maximum pressure switches with automatic reset for general and emergency use. The units are equipped with three pressure switches for compressors emergency, one low pressure probe, placed on suction header for capacity control, one high pressure gauge and one low pressure gauge.

There are also two adjustable high pressure switches to control condenser fan, with automatic reset.

The units are suitable for both outdoor and indoor installation on the floor (with the necessary configurable protections).

These CC-B units are monitored in operation by means of an electrical panel placed on the side of the body, while the electronic control unit centrally manages all the machine parameters.

The electrical panel protected by closing panels includes the disconnecting switch, the standard power distribution system and compressors protection with overload cut-out motor protector.

The electrical panel is IP55 equipped with a grille and a ventilation fan.

The door of the electrical panel is equipped with the electronic unit and 4 alarm lamps for emergency situations and locking of high and low pressure switches. All these features complete the profile of a reliable, safe and extremely versatile machine appropriate to compose and create an efficient refrigerating system suitable to meet a wide range of users’ requirements.
