Super Change™ allows professional HVAC/R contractors a fast and easy way to convert a system from non-POE based oils and refrigerants such as R22 to newer HFC refrigerants including POE-based R407C and R410A without the need to flush the system (excluding compressor burnouts). By adding Super Change with the new refrigerant and oil, a chemical link is created between the old and new oil, thus avoiding a full flush and saving contractors significant time on a system changeout. 1.2 oz single use hose.
