CALFLO™ AF
Heat Transfer Fluid
Introduction
Features and Benefits
Petro-Canada CALFLO™ AF is a highly
efficient heat transfer fluid formulated to
lower operating costs in systems where fluid
resistance to oxidative breakdown is critical.
• Better oxidative resistance than leading
competitors can extend fluid life and
lower operating costs.
• Higher resistance to oxidative
breakdown versus leading competitive
fluids.
CALFLO AF’s unique chemistry starts with a
blend of 99.9% pure base fluids, produced
using the HT purity process. These crystal
clear fluids are free of impurities that can
hinder performance. Utilizing more than 25
years of formulating experience, Petro-Canada
fortifies these thermally stable fluids with
specially selected additives to provide stronger
resistance to oxidative breakdown than leading
competitive fluids.
Applications
Petro-Canada CALFLO AF is recommended
for use in non pressurized, liquid phase,
closed heat transfer systems operating at
bulk temperatures up to 316°C (600°F).
CALFLO AF’s outstanding resistance to
oxidative breakdown can result in longer fluid
life and lower operating costs in systems
where exposure to air cannot be avoided,
and oxidation is the most likely form of fluid
degradation. Typical applications include
temperature control units used in plastic
extrusion, plastic moulding, and metal diecasting operations.
–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
CALFLO AF demonstrates significantly better
resistance to viscosity increase versus a
leading specialty fluid in a severe oxidation
test conducted at an independent industry
laboratory:

Viscosity Increase (%)
The result is CALFLO AF, a heat transfer
fluid that provides high thermal efficiency
in systems operating up to 316°C (600°F).
CALFLO AF’s breakthrough chemistry
can extend fluid life longer than leading
competitive fluids, lowering operating costs by
reducing the frequency of fluid change-outs.
As a fluid oxidizes, it becomes more viscous. This increase in viscosity can:

• Less prone to carbon residue and
sludge formation versus leading
competitive fluids.
CALFLO AF’s resistance to oxidative
breakdown also minimizes the formation
of carbonaceous deposits and sludge
within heat transfer systems. These
deposits can dramatically reduce
heat transfer efficiency and increase
operating costs.
What is the HT
difference?
Petro-Canada starts
with the HT purity
process to produce
water-white, 99.9%
pure base oils. The
result is a range of
lubricants, specialty
fluids and greases
that deliver maximum
performance for our
customers.

resistance to carbon residue formation versus a
leading major oil company’s fluid and a leading

• CALFLO AF does not require special handling.
Shipments and storage of CALFO AF do not
normally require special safety permits. Empty
drums used to transport CALFLO AF are readily
accepted by drum re-conditioners. In addition,
used CALFLO AF 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
CALFLO AF’s high thermal stability provides long
service life under normal operating conditions up to
its maximum recommended temperature. However,
actual fluid life is dependent upon system design and
operating practice.

• Unlike some alternative fluid chemistries,
CALFLO AF is virtually odourless and is not
considered a toxic* substance according to
OSHA (United States), WHMIS (Canada) and
EUDPD (Europe) criteria.
• Because CALFLO AF produces no objectionable
odours and is not a respiratory or skin irritant,
workplace conditions remain pleasant and safe
for continuous operations.

• Low vapour pressure can save on top-up costs
while improving workplace safety.
• CALFLO AF’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 AF’s natural lubricating properties can
also reduce maintenance costs by extending
the service life of circulating pumps and other
rotating parts.
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 coils
• continuously running above the maximum
recommended operating temperature
Although CALFLO AF is highly resistant to oxidative
breakdown, excessive air and water contamination
can reduce thermal efficiency and shorten fluid life.
Where practical, Petro-Canada recommends inert gas
blanketing of a system’s expansion tank to guard
against exposure to air and water and the need to
change-out the fluid prematurely.
While CALFLO AF has been formulated to resist
breakdown when exposed to air and water,
contamination with process chemicals or deteriorated
residual fluids can shorten fluid life. To maximize
system efficiency and fluid life, Petro-Canada highly
recommends system cleaning and flushing to
remove all contaminants, sludge and varnish prior to
recharging a system with CALFLO AF.
