The evaporating capacity of the system will reach a range of temperatures with different charges; including 0,53 MW at -7 °C, 1,87 MW at -5°C, 0,78 MW at 0°C and 0,03MW at -28°C. in addition the systems will also provide 0,15 MW of cooling for for air conditioning purpose cooling.

In total the system will use 45 Bock compressors, made up of 28 medium temperature compressors, 14 parallel compressors and 3 frost compressors …
