Which standard must reclaimed refrigerants meet to be reused?

The standard that reclaimed refrigerants must meet for reuse is ARI 700, which stands for the Air-Conditioning and Refrigeration Institute Standard 700. This standard outlines the purity requirements for refrigerants to ensure that they are safe and reliable for use in HVAC systems. It specifies acceptable levels of contaminants, such as moisture, acidity, and impurities in the refrigerant, thus establishing a clear guideline for what constitutes "reclaimed" refrigerant.

Reclaimed refrigerants must be processed and certified to meet the ARI 700 standard before they can be reused. This ensures that when technicians recover refrigerants from systems, the reclaimed substance will perform adequately and maintain the integrity of the HVAC system it is reintroduced into.

Understanding the significance of ARI 700 also helps technicians discern how to properly handle refrigerants and ensures compliance with industry standards, promoting both environmental safety and system efficiency.
