✅ Key Features
-
Exceptional Miscibility: Offers excellent miscibility and solubility with HFC refrigerants (and newer HFOs), ensuring efficient oil return to the compressor and preventing oil logging in the evaporator.
-
Wear Protection: Provides superior wear protection for internal components (steel and aluminum surfaces), directly contributing to extended compressor life and reliability.
-
Broad Application: Suitable for initial charging in new HVAC/R systems and for service/retrofit applications in existing equipment (after proper oil removal).
-
Energy Efficiency: The formulation is designed for greater lubricity and improved energy efficiency compared to traditional mineral oils in HFC/POE systems.
-
Low-Temperature Performance: Features a very low pour point (as low as -45^C), ensuring good oil flow and lubrication even in low-temperature evaporator conditions.
-
Purity: Has a very low Total Acid Number (TAN) and moisture content, indicative of high product purity and resistance to system contamination.
-
Wide Temperature Range: The superior thermal stability and low-temperature characteristics allow it to operate effectively over a wide operating temperature range.
