Low noise units suitable for outdoor.

The CM series models are air-cooled condensing units equipped with several compressors, suitable for outdoor installations, silenced and ideal for industrial applications.

The series is divided into two product lines. One line with working temperatures from +5°C to -20° and one line with working temperatures from -15°C to -40°C.

The configuration of these units enables a wide choice among many compressors types:
› CM-E | Scroll hermetic compressors
› CM-B | Bitzer semi-hermetic compressors
› CM-D | Dorin semi-hermetic compressors

All the units are assembled starting from a solid pre painted steel sheets frame with a condenser equipped with a speed regulator with thermostatic or pressure control. The condenser is placed vertically on one or two sides of the unit with fans placed on the top cover panel.

The compressors compartment, acoustically insulated to reduce noise during operation, is separated from the condenser by a metal sheet partition which still allows internal ventilation.

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 equipped with liquid receivers with safety valve, filter dryer, liquid level alarm, liquid sight glass and shut-off valves.

As standard equipment and to increase efficiency and safety, 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.

The units are suitable for outdoor installation on the floor.

These multi-compressor condensing units are monitored and customizable 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, compressors protection with overload cut-out motor protector and fuses for fans protection with thermo contacts for each single fan.

Four alarm signals, fans block, high and low pressure switch block 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.
