Solution for condensing units and compact compressor racks

A cutting-edge system for compact and efficient compressor racks

µRackoffers allthe featuresneededforthe controlof smallcondensingunitsand compressor racks, guaranteeing reliability, efficiency and ease-of-use.

• Control of 2 suction line, up to 4 compressors and a first modulating compressor (with HFC/HFO refrigerants up to 6 compressors: 4MT- 2LT);
• dedicated functions for oil return: to protect the compressors;
• control of a condensation line: EC modulating fans and up to 4 ON-OFF fans.

µRack was created to renew the proposal of controls for condensing units and small compressor racks. Usability has been revolutionised through advanced connectivity, which complements the precision control and energy-saving features developed and established in CAREL’s range of compressor rack controllers.

Interaction with mobile devices

• Advanced connectivity and next generation user experience. The simplicity and effectiveness of the configuration from smartphones and tablets can reduce the unit’s initial start-up time and simplify maintenance activitie

Energy savings

• Features such as floating condensing stage control, fan modulation, heat recovery and compressor speed control help minimise energy consumption.

Compressor protection

• Prevention of liquid return to the compressors with low superheating control to maximise machine reliability. Support for different types of compressors: piston and scroll.

µRack CO2: simple control for transcritical CO2

• Management of the high pressure valve (HPV): calculation of the optimal pressure and continuous modulation to ensure most efficient operating conditions at all times
• Flash gas valve (FGV) management: pressure control in the liquid receiver.
• Single-stage heat recovery: function that exploits the heat normally expelled from the gas cooler to produce hot water (domestic or industrial uses) or for heating/ventilation systems
