Group 3:
Mobile extraction and charging systems for filling compressed-gas vessels permanently connected to the system.
The refrigerant or refrigerant/oil mixture is transferred to compressed gas vessels which are permanently connected to the mobile systems. In accordance with 3 Para. 5 No. 3 of pressure vessel regulations, compressed-gas vessels are classified as pressure vessels in this case.
The charging systems require:
no permit
no expert testing as the gas is transferred to compressed-gas vessels which are classed as being pressure vessels. (Systems used for transfer from these pressure vessels to compressed-gas vessels for supplying to third parties do require a permit and are subject to mandatory testing).
  Note
The A/C service and recycling units used in motor vehicle workshops are extraction and charging systems not requiring a permit (Group “3”) but which are only to be operated by qualified personnel.
