Heat transfer fluid, DW-Therm (-90 to 170°C), 10L
Information
DW-Therm is a mixture of isomeric triethoxysilanes and has been developed for hydraulically sealed systems.
We recommend the heat transfer fluid DW-Therm for Unistats. DWTherm has a high specific heat capacity and so contributes towards an optimum heat transfer. In addition, DW-Therm covers a large temperature range, and has an impressively long service life.
Advantages:
- Valid only for Unistats
- Size 10L
- Broad working range from -90 °C to 200 °C (hydraulically sealed systems)
- excellent thermo-oxidative stability at high temperatures
- Low viscosity at low temperatures
- Low volatility and pleasant odor
- Easy handling (no creeping like silicone oils)
- Good compatibility with silicone oils
- Insoluble in water and good environmental combability
