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

Huber SilOil M20.195/235.20, Heat transfer fluid -20 to 235 °C   SilOil M20.195/235.20 is a low-viscosity silicone fluid which, as a result of its special property profile, is particularly suitable for use as a cold and heat transfer medium in cryostats, thermostats and heat transfer installations.   SilOil M20.195/235.20 can be used in the range from -20 °C to 195 °C (for open systems) and to 235 °C in externally sealed systems (Unistats). It should be borne in mind that, at high temperatures, SilOil M20.195/235.20 can be chemically altered by oxidising media, such as air, or substances with a catalytic effect, such as acids, lyes and various metal compounds. An increase in viscosity, and possibly even gelling of the fluid owing to crosslinking reactions, must be expected in the presence of oxidising agents, while contact with products having a catalytic effect usually induces a process of depolymerisation, resulting in a drop in viscosity. Advantages:  Virtually insolubile in water Non-corrosive Low setting points and vapour pressures high flash points low toxicity odourless no coking tendency under thermal stress high thermal stability resistance to ageing   Safety Data Sheet    Heat transfer fluid M20.195/235.20 Working temperature °C -20 to 195/235 open/closed systems: -20°C…195°C Unistats (only closed): -20°C…235°C Material: silicon oil Viscosity at 25°C: 20 mm²/s Colour colourless, clear Material incompatibility Silicone rubber
