Petro-Canada PURITY FG Heat Transfer Fluid

Product Description

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.


Type / Applications

  • Biodegradable
  • Heat Transfer Fluid
  • Food Grade

Higher thermal and oxidative stability than leading competitors which can help extend fluid life and lower operating costs

• More thermally stable than leading competitive fluids, even full synthetics

Thermal stressing of a heat transfer fluid can cause the formation of light molecular compounds. These compounds can:

• Raise a fluid’s vapour pressure, which can cause fluid leakage from control valves and pipe flanges, circulating pump cavitation and vapour locking

• Dramatically reduce a fluid’s autoignition temperature, the lowest temperature that a fluid will combust, without flame or spark, in the presence of oxygen

• Lower the operating temperature at which the heat transfer system can safely operate

• Necessitate a costly, premature fluid change-out

Petro-Canada PURITY FG Heat Transfer Fluid is recommended for use in non pressurized, liquid phase, closed heat transfer systems used in food processing or pharmaceutical operations with continuous bulk operating temperatures up to 326°C (620°F). Typical applications include central cooking facilities, drying, edible oil deodourizing and the heating of deep frying oils. PURITY FG Heat Transfer Fluid may also be used in heating baths where a virtually odourless, non-toxic* fluid is required for worker health and safety.

PURITY FG Heat Transfer Fluid’s outstanding resistance to oxidative breakdown is also beneficial in food related manufacturing operations where exposure to air can not be avoided, and oxidation is the most likely form of fluid degradation. Common applications include the manufacture of plastic bottles, films and containers for the packaging of food products.
