Compressor racks and condensing units, manufactured by Soko Inžinjering, are intended for commercial refrigeration.

The following refrigerants are used: R404A, R448A and R449A.

Compressor racks consist of two, three or four semi-hermetic compressors operating in the parallel system.

Combination of several compressors varying in their capacities enables production of sufficient number of unit sizes.

Compressor racks are equipped with all the elements necessary for regulation, protection and safety, with high level quality guarantee. This type of compressor racks has the following advantages: energy conservation, shorter outdoor installation time and easier maintenance.

RAMT-Series compressor racks are intended for medium temperature cooling. Our standard production involves 10 sizes covering cooling capacity range of 7 kW to 63 kW at the following conditions te = -10ᴼC, tc = 45ᴼC (for R404A).

RALT-Series compressor racks are intended for low temperature cooling. Our standard production involves 6 sizes covering cooling capacity range of 5 kW to 23 kW at the following conditions te = -35ᴼC, tc = 45ᴼC (for R404A).

Every compressor rack has its own control electric cabinet with a controller that secures reliable operation of the compressor rack, meeting all the planned parameters and optional connection with the central surveillance and management system.

Control electric cabinet contains all the elements required for protection, management and signalisation.

The following types of controllers are used to manage compressor racks operation:

  • “CAREL” pRack Pr300 or
  • “Danfoss” AKPC 551.

Compressor racks casings are made of painted galvanised metal sheets of adequate strength, which rest on suitable rubber absorbers.

Compressor racks are located in mechanical rooms built in accordance with the standards and provisions dealing with manipulation, service and ventilation.
