compact *carbo-Rack

transcritical CO2 plants and optimized refrigeration with the CO2 Booster series *carbo-Rack.





The *carbo-Rack series is perfectly suited to the requirements in the retail food segment. By using the environmentally friendly refrigerant CO2 with a GWP of 1, all cooling requirements can be met safely, efficiently and in compliance with all the applicable standards and laws.

*carbo-Rack allows a free combination of compressor racks for LT and MT refrigeration. This allows a high degree of flexibility.

*carbo-Rack works with 3 compressors for LT and up to 4 compressors for MT stage. This increases the operational safety and provides better performance levels. For further efficiency improvement, parallel compressors and *c-Ejector may be utilised.

*carbo-Rack offers a fine gradation of the cooling capacity of deep and normal refrigeration.

*carbo-Rack comes with a frequency inverter on each main compressor for each pressure stage. Sub- and transcritical conditions are mastered safely and efficiently.
