About this document
HFC Refrigerant Compatibility Testing by Curtis Lawson is a document available to read on EtoBox.
The document summarizes testing done to evaluate the compatibility of desiccants used in filter-driers with new HFC refrigerants and polyol ester lubricants. Sealed tube tests showed molecular sieves and activated alumina to be compatible, with HFC refrigerants like R-134a showing very low decomposition compared to older refrigerants. Field tests of systems using R-134a and polyol ester oil also demonstrated the filter-driers kept contaminant levels low over time. The conclusion is that filter-driers contin
