Recycling means to process refrigerant recovered from a system through a cleaning and decontamination process so that it is suitable for reuse. This does not imply that its purity meets the cleanliness specifications for new refrigerants. Recycling is usually performed at the job site or service shop using a recycling unit or a combined recovery/recycle unit (Figure SP-2-2). Recycled refrigerant is only reusable by the owner of the equipment being serviced.
