Huber Heat Transfer Fluids

Huber DW-Therm M90.200.02, Heat transfer fluid -90 to 170 °   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 thermooxidative stability at high temperatures Low viscosity at low temperatures Low volatility and pleasant odour Easy handling (no creeping like silicone oils) Good compatibility with silicone oils Insolubile in water and good environmental compability   Safety Data Sheet     Properties Working temperature °C -90 to 200 Flash Point °C 101 Fire Point °C 112 Viscosity mm2/s (kinematic at 25 °C) 2 Density g/cm3 (at 20 °C) 0,879 Pour Point °C -137 Ignition temperature °C 265 Colour yellowish, clear Thermal expansion coefficient 10-5/K 96,98 Heat conductivity W/(m·K) at 25 °C 0,116 Material incompatibility copper, aluminum,non-ferrous metals
