Gas pre-heater for indirect heating of gases

Gas pre-heaters made by Herbst Beheizungs-Technik consist of an electric heating element and a tube coil which are both cast in an aluminium block.


Industrial and process gases or even fluids are directed through the tube coil which is heated up by the aluminium block, thus, ensures an extremely constant and precise heat transmission.


The illustrated standard version can be individually adapted to customer’s requirements. Other connection types, capacities and dimensions are available on request.
