What is the HT difference?

Petro-Canada starts with the HT purity process to produce water-white, 99.9% pure base oils. The result is a range of lubricants, specialty fluids and greases that deliver maximum performance for our customers.


Calflo is a line of specialty heat transfer fluids produced from Petro-Canada's, 99.9% pure based oils and patented additive technology. The Calflo family of advanced fluids is recommended for use in non-pressurized, liquid phase, closed heat transfer systems.

  • Product Description


    Petro-Canada CALFLO™ AF is a highly efficient heat transfer fluid formulated to lower operating costs in systems where fluid resistance to oxidative breakdown is critical. CALFLO AF’s unique chemistry starts with a blend of 99.9% pure base fluids, produced using the HT purity process. These crystal clear fluids are free of impurities that can hinder performance. Utilizing more than 25 years of formulating experience, Petro-Canada fortifies these thermally stable fluids with specially selected additives to provide stronger resistance to oxidative breakdown than leading competitive fluids. The result is CALFLO AF, a heat transfer fluid that provides high thermal efficiency in systems operating up to 316°C (600°F). CALFLO AF’s breakthrough chemistry can extend fluid life longer than leading competitive fluids, lowering operating costs by reducing the frequency of fluid change-outs.

  • Applications

    Heat Transfer Systems

    Aluminium Smelters

    Petro-Canada CALFLO AF is recommended for use in non pressurized, liquid phase, closed heat transfer systems operating at bulk temperatures up to 316°C (600°F). CALFLO AF’s outstanding resistance to oxidative breakdown can result in longer fluid life and lower operating costs in systems where exposure to air cannot be avoided, and oxidation is the most likely form of fluid degradation. Typical applications include temperature control units used in plastic extrusion, plastic moulding, and metal diecasting operations.
