Quality of Refrigerant Gases and Certified Guarantees

Mixed refrigerants

Mixed refrigerants are another problem that professionals frequently encounter in the field, and they are also a major concern. Mixed, low-quality refrigerants can not only damage HVAC-R systems, but can also pose a threat to the safety of technicians who are servicing the equipment, especially if it is a flammable or toxic component.


In the field, the only way to determine whether the refrigerant meets the AHRI 700 standard, which specifies the purity requirements of refrigerants, is to test it with an analyzer (recovery companies have more comprehensive analysis capabilities). While these can be expensive tools, some say they're worth the investment.


The increasing number of refrigerants and substitutes now available has significantly increased the chances of a system being loaded with various refrigerants. Not only can this have an adverse effect on an HVAC-R system, but it can make it difficult for professionals in the area to receive the best price for their recovered refrigerant.


In fact, refrigerant analyzers can be expensive, with premium units costing about $4,000 or more, which is why they're not routinely found at most companies in the industry.


An analyzer is mainly used by recuperators or anyone who consolidates large amounts of refrigerants, detects any problematic mixtures, avoiding costly cross-contamination or residual mixtures in an indicated refrigerant.
