Petro-Canada PURITY™ FG Heat Transfer Fluid is formulated to help lower operating costs by reducing the frequency of fluid change-outs in operations that require a food grade product. PURITY FG Heat Transfer Fluid’s unique chemistry starts with a blend of 99.9% crystal-clear base fluids, produced from a HT Purity Process. These crystal-clear fluids are free of impurities that can hinder performance. Utilizing more than 30 years of formulating experience, Petro-Canada fortifies these thermally stable fluids with specially selected additives to provide outstanding protection from oxidative breakdown. The result is PURITY FG Heat Transfer Fluid, a food grade fluid that provides high thermal efficiency in systems operating up to 326°C (620°F). PURITY FG Heat Transfer Fluid's breakthrough chemistry can assist in extending fluid life longer than leading competitive fluids, and help lower operating costs by reducing the frequency of fluid change-outs.
