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 pure HT hydrocracked base oils and a patented 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.
Petro-Canada CALFLO™ AF is recommended for use in indirectly heated, liquid phase heat transfer systems operating continuously at temperatures up to 316°C (600°F). The oxidative stability of CALFLO™ AF is especially valuable in open systems where oxidation is the most likely form of fluid degradation. These applications include temperature control units found in plastic extrusion and moulding and in aluminium and magnesium die-casting.
