Evacuating refrigeration systems
The professional and reliable execution of an evacuation is an indispensable work step before the initial commissioning or recommissioning of a refrigeration system. This ensures that there is no moisture, foreign gases, oil and refrigerant residues in the refrigeration system before charging.
