Heat Transfer Oil Specifications
ISO Grade 68 Heat transfer Oil Specification
There are many different types of Heat Transfer Oils on the international marketplace. It is criti-
cal that you use the proper oil to prevent poor performance, oil flashing, or auto-ignition. To
conform to most government bids and to supply a readily available product, CIMLINE typically
uses brands manufactured by Conoco or Phillips 66 that meet the ISO Grade 68 Heat Transfer
Oil specifications listed. To insure maximum safety and performance, we recommend you pur-
chase your oil through CIMLINE.
ISO VG# 68
Pour Point - F
10º F (12º C)
Flash Point - F
485º F (252º C)
Lbs/Gallon 7.27
Viscosity CsT @ 40C 62
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 con-
form to different applications.
YOU MUST CLARIFY with the supplier that the oil is to be used
in a heat transfer system to avoid any potential problems. 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 ex-
posed 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 ex-
posure 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 is 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 exposed to air.
