Overview
Heat Transfer oil is a heat-transfer fluid made from paraffinic base oil and additives, for closed and open heat-transfer systems at atmospheric pressure. Grades: HT 32.
The specification table lists each grade separately, with the test method for every value, so grades can be compared directly before ordering.
Application
Indirect heating circuits at atmospheric pressure; the maximum bulk temperature differs between open and closed systems and is confirmed against the approved documentation.
Feature
HT 32: KV40 32 cSt, KV100 5.5 cSt, VI 100, pour point -18 °C, flash point 210 °C.
Follow the equipment manufacturer's viscosity recommendation at operating temperature, then compare the grades' published values in the specification table.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
