A heating medium is any solid or fluid (such as water, steam, air, or flue gas) which is used to convey heat from a heat source (such as an electric immersion heater) to a process or space being heated. Electric heat is often used as a temporary or permanent solution to heat the medium which is then used in various types of heat exchangers throughout the plant.
When electric heat is used permanently to heat the medium which in turn is used in a process, we ask our customers: “Could you use electric heaters directly in the process?” The positive answer usually reduces the overall cost of the process design. But also as a central heater for the supply of entire plants, electric central heaters are increasingly being used instead of fired systems. The advantage for the operator is obvious, as there is no need for emissions trading when using electric heaters.
