Chilller Refrigerant Tests

The most common contaminants found in refrigerants are air, moisture and oil. Air and oil reduce efficiency and moisture can seriously damage the system.

Testing refrigerants for water, acidity and the presence of high boiling impurities protects system metals, sealants and gaskets from potentially harmful contamination that can reduce the overall energy
efficiency of the unit and increase the risk of system damage.
