The UM-V models are air cooled screw chiller and compression units equipped with screw compressors, designed to be part of freezing systems for industrial use.

The series includes the UMX models, which guarantee an operating temperature range from -30° to -45°, with power consumption range from 100 to 390 kW.

The power range covered varies from 60 to 400 kW in the largest models, with the option to compartmentalize capacity during operation.

The UM-V units are built around a sturdy base in welded sections which is provided with the semi-hermetic compressor equipped with anti-vibration tubes, the liquid receiver complete with inlet and outlet taps and safety valve, and the oil separator equipped with resistance, thermostat and oil level control.

All units in the series are equipped with a module for motor control and with module for oil control.

A unique element of the UM-V series is the presence of the 2 or 3 screw compressors: equipped with 2 capacity reduction steps, this type of compressor allows the suction point to be set by varying the compression level and the power supplied for an increase of flexibility and efficiency during machine operation.

The standard equipment also includes:
– filter, liquid indicator and tap on the liquid line;
– liquid separator, filter and tap on the suction line;

– check valve on the delivery line;
– for each compressor, filter, flow switch, solenoid valve and indicator on the oil line.

The equipment of the UM-V is completed by the air-supplied oil cooler with motor fan controlled by electronic thermostat, the economizer system equipped with plate heat exchanger complete with solenoid valve and thermostatic valve for each compressor and minimum and maximum pressure switches with automatic reset.

The non-faired structure requires a ground installation in a closed environment.

The unit fairing option is available to allow external positioning.

All UM-V units are supplied with pressurized helium, pre-loaded with polyester oil and already tested with respect to pressure tightness and electrical safety devices.

The management of the machine is easy and instant thanks to the equipment of the electrical panel mounted on board: completely wired, it is equipped with fuses, isolation transformer, thermal relays to protect the compressors and remote control switches for the motor fans and the compressors.

The electrical management module has been designed to control all of the functions of the UM-V unit, completing the profile of a versatile, reliable and efficient product.
