Description:

Petro-Canada CALFLO™ Synthetic is a synthetic heat transfer fluid specifically formulated for extremely cold climates where ambient temperatures can reach -48°C (-54°F). CALFLO Synthetic’s unique chemistry is based on synthetic poly-alpha-olefins and specially selected additives that deliver outstanding protection while remaining virtually free of impurities and aromatic compounds that can be hazardous to workplace health and safety.

The result is CALFLO Synthetic, a heat transfer fluid that provides high thermal stability and excellent cold temperature pumpability in extreme start-up operating conditions as low as -48°C (-54°F). CALFLO Synthetic’s breakthrough chemistry balances low temperature fluidity with outstanding oxidative stability and volatility control. Equally important, the fluid’s purity ensures no compromise to the environment or workplace health and safety.

Features & benefits:

• High thermal and oxidative stability can help to extend fluid life and lower operating costs

• 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

• A fluid’s resistance to oxidative breakdown is critical in heat transfer systems where exposure to air is likely or can not be avoided. Strong oxidative resistance can significantly extend fluid life, and may provide operational savings by reducing fluid change-out frequency and down time.

• High resistance to oxidative thickening. 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

• Natural lubricity extends operational savings.

• CALFLO Synthetic’s natural lubricating properties can also help to reduce maintenance costs by extending the service life of circulating pumps and other rotating parts.

• No compromise to environmental and workplace health and safety.

• Unlike synthetic aromatic fluids, CALFLO Synthetic is virtually odourless and is not considered a toxic* substance according to OSHA (United States), WHMIS (Canada) and DPD (Europe) criteria.

• Because CALFLO Synthetic produces no objectionable odours and is not a respiratory or skin irritant, workplace conditions remain pleasant and safe for continuous operations.

• Shipments and storage of CALFLO Synthetic do not normally require special safety permits. Empty drums used to transport CALFLO Synthetic are readily accepted by drum reconditioners. In addition, used CALFLO Synthetic may be responsibly disposed in the following ways**:

- through re-sale to used oil recycling companies - in some jurisdictions, combined with BTU recovery systems

Applications:

Petro-Canada CALFLO Synthetic is recommended for use in non-pressurized, liquid phase, closed heat transfer systems operating continuously at moderate bulk temperatures. CALFLO Synthetic’s low viscosity ensures outstanding heat transfer efficiency even at moderate operating temperatures while its low temperature fluidity ensures excellent pumpability under extreme conditions, eliminating the need for expensive heat tracing and insulation in outdoor applications with ambient temperatures down to -48°C (-54°F).
