Petro-Canada’ s CALFLO AF is an efficient heat transfer fluid designed for use in systems operating continuously at temperatures up to 316° C ( 600° F) . CALFLO AF is a blend of our exceptionally pure HT hydrocracked base oils and a patented Petro-Canada additive system. This combination makes CALFLO AF particularly effective in open systems where oxidation resistance is essential. CALFLO AF delivers excellent heat transfer efficiency, superior oxidative and thermal stability, together with low toxicity.
