Huber thermal fluids have the best possible thermodynamic and environmental characteristics. The correct selection is vitally important and and is dependent on the temperature range.
Consideration must be given to the safety standards to ensure reliable, safe operation and optimum results.
The material safety data sheets for a selection of heat transfer fluids are available to download below and details of the 'Unistat only' DW-Therm fluids are highlighted.
