Quality control for all refrigerants
At Darment, we ensure that every batch of refrigerant that enters our warehouse undergoes a comprehensive quality analysis. This guarantees that the refrigerants our customers receive are pure, safe, and compliant with technical and legal standards.
Our quality control process produces refrigerant analysis based on the AHRI-700 standard. Get to know the details of the standard here:
We require our suppliers to comply with the standard.
Why we analyze all refrigerants
Refrigerants directly affect the performance, safety, and lifetime of your cooling equipment. Even small impurities or imbalances can:
- Decrease system efficiency
- Corrode internal components
- Cause compressor failures
- Lead to unexpected system downtime
To protect our customers from these risks, we verify the chemical integrity and cleanliness of each refrigerant batch before it is released for sale.

What we check
Our analysis covers the most critical quality factors:
- Air content
- Moisture (ppm)
- Acidity / Acid number
- Oil content
- Volatile components & impurities
- Solid particles (metals, scale, fibers)
- Component balance (especially for refrigerant blends)
Only refrigerants that pass all quality criteria are approved for sale.
For pure refrigerants, we do not perform the full analysis panel. We only check air content, moisture, and the refrigerant components and their purity.
We assume that unused refrigerants do not contain acids or oil.
Ensuring safe use and long-term performance
Contaminated or unbalanced refrigerants are a major cause of equipment failure. By analyzing and certifying every incoming refrigerant, we:
- Reduce the risk of field failures
- Help you maintain equipment warranties
- Ensure compatibility with system components
- Support energy efficiency and environmental responsibility
