Excellent medium-weight, mineral-base oil for halocarbon refrigerants. FRICK #2A oil is refined free of waxes that may congeal or precipitate at low evaporator temperatures. This oil has a naturally low pour point requiring no pour point depressants and a natural affinity to halocarbon refrigerants for good oil return and heat transfer. It is recommended for evaporator temperatures -50°F and above. FRICK #2A oil offers the lowest, first-cost alternative for halocarbon refrigerant applications.
