Product Announcement from Paratherm Corporation
Because thermal fluids operate in closed- loop systems (no continuous exposure to air), they require different tests and testing frequency than lubricating oils or hydraulic fluid which operate in open systems (continuous exposure to air). Thermal fluids usually only need to be tested once a year since there are no additive packages that need to be monitored and controlled or water contamination to worry about (water in a thermal—fluid system makes itself known pretty quickly). So the test values that matter are:
- Acid Number
- Distillation Range
And Paratherm has the specific equipment (its not the same as is used for lubes) and expertise to develop and discuss meaningful results.
