ISO Grade 68 Heat transfer Oil Specification
There are many different types of Heat Transfer Oils on the international market-
place. It is critical that you use the proper oil to prevent poor performance, oil flash-
ing, or auto-ignition. To conform to most government bids and to supply a readily
available product, CIMLINE typically uses brands manufactured by Conoco or Phil-

IMPORTANT NOTICE!!
The ISO Grade is just a viscosity index (ability to flow/thickness). An ISO Grade 68
oil can be an engine oil, hydraulic oil, etc. The manufacturer uses different additives
to make the oil conform to different applications.
YOU MUST CLARIFY
with the sup-
plier that the oil is to be used in a heat transfer system to avoid any potential prob-
lems. Oil is also available from CIMLINE in 5 and 30 Gallon containers for ship-out.
NOTE:
CIMLINE Melter/Applicators include and expansion tank that cools the oil
that is exposed to the outside air. When the oil heats up and expands, it flows into
the expansion tank. The tank is cooler since it is not oil jacketed and is surrounded
by outside airflow. The only exposure the hot oil has to the atmosphere is through a
3/4" vent/overflow pipe. This is done so the oil in the tank can run higher than the
flash point. Only the lower temperature oil fumes are exposed to the atmosphere.
FLASH POINT -
Test in which an open container of oil can heated until an open
flame will flash when passed over the fumes.
FIRE POINT -
Same test as the flash point except the oil is heated until the gasses
will start a fire.
AUTO IGNITION POINT -
The point at which fumes will burst into flame when ex-
posed to air.
