The refrigerant sample is testing in according to the parameters required to complies with AHRI 700 standard.

We realize the assay required for our costumer of any parameter in the standard.

Services

Analysis of identification of refrigerants.

We test to know what is the identity of the refrigerant, after that the quality analysis of it.
