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

Our Clients

This is the easiest way to estimate a manufacturer's market reputation and credibility. Check out the list of clients that the manufacturer has worked with or continues to work. The more and larger companies that they have as clients, the better you can trust them. After all, weren't they good enough, big brands would not have worked with them in the first place.
