About Globaltherm® Omnitech

Globaltherm® Omnitech is a synthetic thermal fluid which combines low viscosity and exceptional thermal stability for consistent performance.

  • Globaltherm® Omnitech is a diphenyl ether-biphenyl HTF mixture
  • The eutectic mixture of diphenyl oxide and biphenylgives this heat transfer fluid flexibility to perform in both vapour and liquid phases. It is miscible and interchangeable (for top-up or dilution purposes) with other similar mix thermal fluids.
  • Globaltherm Omnitech HTF has low viscosity (2.5 cst at 40°C [104°F])
  • This thermal fluid is excellent for use in heat transfer fluid systems which require very precise temperature control due its ability to operate as a vapour phase fluid
  • This heat transfer fluid is highly dependable
