At what percentage is refrigerant considered pure and safe for recovery?

Refrigerant is considered pure and safe for recovery when it reaches a content level of 98% or greater. At this concentration, the refrigerant is largely free from contaminants such as water, oils, or debris, which can adversely affect the recovery process and the integrity of the recycling system.

Refrigerants that are not sufficiently pure can complicate recovery processes, leading to inefficiencies, potential damage to recovery equipment, and issues with legal compliance regarding refrigerant handling. In many regulatory frameworks, maintaining a high purity level of refrigerant during recovery is essential for environmental safety and compliance with established guidelines.

In practice, a refrigerant purity threshold of 98% ensures that the substance can be processed effectively without introducing harmful substances into recovery systems or the environment, thus making it the correct choice in this context.
