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
