Neste Therm S 8
Product number 338211
Synthetic heat transfer oil
- Good thermal stability
- Excellent oxidation stability
- Low vapour pressure
Neste Therm S 8 is a fully synthetic heat-transfer oil with a lower vapour pressure and higher flash point than mineral oils. It stands continuous high temperatures without oxidation and forms no carbon deposits or sludge in a correctly designed system. The specific heat of Neste Therm S 8 is higher than that of mineral oils and it can be used even with start-up at low temperatures.
