Refrigerant Recovery

The recovery of refrigerant removes refrigerant in any condition o f purity from a system or container for storage in an approved external container (recovery cylinder). No processing is necessarily done on the recovered refrigerant. Currently, recovered refrigerant is only reusable if it does not change ownership from the owner of the equipment being serviced.

Recovery of refrigerant from a system is done using a certified recovery unit (Figure SP-2-1) or a combined recovery/recycle unit (Figure SP-2-2). Recovery must be performed:
• Before a refrigeration system can be opened to make repairs.
• Before pressurizing a system for leak testing with a mixture of HCFC-22 refrigerant and nitrogen.
• Before disposing of any system or component containing CFC or HCFC refrigerants.
• When it is necessary to remove excess charge from an overcharged system.

  1. Refrigerant recovery is not only an easy task but also a delicate task. Hi, I hope you can help. One of our radiators has started making the strangest noise. It sounds like a paper bag being scrunched and always happens just after the hot water tap is turned on, and sometimes happens when the water tap isn’t on. Do you have any idea what this could be? Thanks, MATT
