Description :
sigma THERM®- D is a superior performance heat transfer fluid. Latest technology is used to produce Modified Hydrocarbon/ Engineered Hydrocarbon. This highest performance fluid is used as base oil in formulation of the product. Its thermal stability matches with synthetic thermic fluid in similar operating range.
Application :
Indirect closed heat transfer systems : 0 °C to 260 °C
Benefits :
- Higher rate of heat transfer
- Lower time required to achieve operating Temperature
- Lower load on circulation pump
- Lower power rated circulation pump is also suitable
- Reduces Fuel Consumption.
Special Note :
Proper Heat Transfer Fluid selection is a very crucial job. Generally all products available in the market are for high temperature application. But till date none of the proper product is there for medium temperature range.
Co-efficient of heat transfer ( heat transfer rate ) is inversely proportionate to Kinematic Viscosity of the heat transfer fluid at operating temperature.
Mixability :
sigma THERM®- D has been thoroughly tested in the laboratory with different proportionate of other thermic fluid at various high temperatures for stability and other related parameters.
Based on results it is proved that sigma THERM®- D could be used for top-up purpose in the systems already containing mineral based thermic fluids or Synthetic based thermic fluid.
Compatibility :
Metal : sigma THERM®- D is compatible with all metals.
