Description
Description:
Petro-Canada Lubricants 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 a synthetic poly-alphaolefin base oil 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.
Applications:
Petro-Canada Lubricants CALFLO Synthetic is recommended for use in non-pressurized, liquid phase, closed heat transfer systems operating continuously at moderate bulk temperatures up to 216°C (420°F). 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).
Features and 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 auto-ignition temperature, the lowest temperature at which 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.
• 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 re-conditioners. 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
Operational Considerations:
While CALFLO Synthetic’s excellent low temperature pumpability allows cold system start-up in extreme temperatures as low as -48°C (-54°F), parameters for systems operating continuously below 5°C (41°F) should be reviewed with an HF Sinclair Technical Service Advisor to determine the suitability of the fluid in its specific operating environment. CALFLO Synthetic is specially formulated to provide long service life under normal operating conditions. However, actual fluid life is dependent upon system design and operating practice. Special precautions should be taken to avoid operating conditions that can shorten fluid life. These include:
• thermal shocking resulting from accelerated system temperature increases
• thermal shocking from hot spots on a system’s heating coil
• continuously running above the maximum recommended operating temperature
While CALFLO Synthetic is highly resistant to oxidative breakdown, excessive air and water contamination can reduce thermal efficiency and shorten fluid life. Inert gas blanketing of a system’s expansion tank is recommended to guard against exposure to air and water and the need to change-out the fluid prematurely.
Although CALFLO Synthetic has been formulated for high resistance to contamination from air and water, contamination with process chemicals or deteriorated residual fluids can shorten fluid life. To maximize system efficiency and fluid life, system cleaning and flushing is recommended to remove all contaminants, sludge and varnish prior to recharging a system with CALFLO Synthetic.
