THERMIC-FLUIDS
Application areas:
Hytherm S gives excellent performance in high temperature Heat Transfer. When provided with proper nitrogen blanketing this fluid can perform well and resist thermal cracking over a period of time leading to lower drop in flash point as compared to mineral oils. This is an excellent heat transfer fluid and finds a wide range of applications in Textile, Pharmaceutical, Chemical and Processing units.

HYTHERM S
Hytherm S is a premium quality Heat Transfer Oil specifically developed for heat transfer system where skin temperature goes up to 345°C and bulk temperatures up to 330°C. This product is derived from synthetic base stocks and is fortified with high performance additives to enhance the performance at higher temperature.
THE SALIENT FEATURES ARE GIVEN BELOW:
- Ability to withstand higher bulk operating temperatures up to 330°C
- Reduced oxidation and improved thermal degradation, hence longer life
- Reduced tendency of thermal cracking and hence lower drop in flash point as compared to mineral oil
