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.


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.

Features and Benefits

• Better oxidative resistance than leading competitors can extend fluid life and lower operating costs. • Higher resistance to oxidative breakdown versus leading competitive fluids. As a fluid oxidizes, it becomes more viscous. This increase in viscosity can: – significantly reduce a fluid’s thermal efficiency – make the fluid more difficult to circulate through the heat transfer system – result in overheating of the fluid – necessitate a costly, premature fluid change-out

CALFLO AF demonstrates significantly better resistance to viscosity increase versus a leading specialty fluid in a severe oxidation test conducted at an independent industry laboratory.
