Description:

Petro-Canada CALFLO™ HTF is a high temperature heat transfer fluid formulated to provide long service life, without compromise to environmental and workplace health & safety.

CALFLO HTF’s unique chemistry starts with a blend of 99.9% pure base fluids, produced from a HT purity process. These crystal-clear fluids are free of impurities and aromatic compounds that can be hazardous to workplace health and safety. Utilizing more than 25 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 CALFLO HTF, a heat transfer fluid that provides high thermal efficiency, in high temperature systems, over a long and reliable service life. Yet CALFLO HTF does not raise the same objectionable odours, workplace health and safety, and environmental concerns that are problematic with synthetic aromatic compounds.

Features & benefits:

More resistant to oxidative breakdown than chemical aromatic competitive fluids.

• A fluid’s resistance to oxidative breakdown is critical in heat transfer systems where incidental exposure to air may occur. Strong oxidative resistance can significantly extend fluid life, providing operational savings by reducing fluid change-out frequency and down time.

• CALFLO HTF’s strong resistance to oxidative breakdown can extend fluid service life in tough working conditions where fluid exposure to air is likely or can not be avoided.

• This resistance to fluid breakdown can greatly reduce the formation of highfouling, carbonaceous deposits that can significantly reduce heat transfer system efficiency and increase operating costs.

Low vapour pressure can save on top-up costs while improving workplace safety.

• CALFLO HTF’s low vapour pressure can reduce or eliminate fluid leakage from control valves and pipe flanges.

• Reduction or elimination of leaks provides a cleaner and safer operating environment, and results in operational savings by reducing the need for cleaning, maintenance and fluid top-up.

Natural lubricity extends operational savings.

CALFLO HTF’s natural lubricating properties can also 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 HTF is virtually odourless and is not considered a toxic* substance according to OSHA (United States), WHMIS (Canada) and DPD (Europe) criteria.

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

• CALFLO HTF does NOT require special handling. Shipments and storage of CALFLO HTF do not normally require special safety permits. Empty drums used to transport CALFLO HTF are readily accepted by drum re-conditioners. In addition, used CALFLO HTF 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 HTF is recommended for use in non pressurized, liquid phase, closed heat transfer systems operating at bulk temperatures up to 326°C (620°F), with tubeskin temperatures as high as 343°C (650°F)
