SIGMA THERM® - V

Description :

sigma THERM®- V is a Ultra Low Temperature Heat Transfer Fluid used in Single Fluid Heating and Cooling applications.

Application :

Indirect closed heat transfer systems : (– 115) °C to 175 °C

This single fluid caters the dual demand heating and cooling in Pharmaceutical, Fine Chemicals and other industries.

It has got boiling point of 99°C. For higher operating temperature care should be taken for proper design of system. It is highly recommended to use Nitrogen Blanketing in expansion tank. Pressure release devices should be provided at appropriate places.

Benefits :

  • Simplifies by eliminating multiple fluids for heating and cooling.
  • Engineered for Longevity and lasting performance.
  • Cost optimised Solution for maximum value.
  • Effortless operations with minimum maintenance.

Compatibility :

Metal : sigma THERM®- V is compatible with all metals.
