SIGMA THERM-K

sigma T H E R M® – K has lower Viscosity as compared to other thermic fluids – lower power consumption of circulating pump and high co- efficient of heat transfer.

sigma T H E R M® – K has been thoroughly tested in the laboratory with different proportionate of mineral oil at various high temperatures for stability and other related parameters.

Based on results it is proved that sigma M® – K could be used for top-up purpose in the systems already containing mineral oil based thermic fluids or similar chemistry synthetic fluid.

Application :

Indirect closed heat transfer systems up to 320°C.
For best life it should be used at or below 300°C.

Benefits :

As compared to other mineral based thermic fluid,
it has.

  • High thermal stability.
  • High oxidation stability
  • Very low carbon deposits.
  • Long Life.
  •  Reduced “ Low Boilers “ and “ High Boilers
