THERMOCOAX offers a specific range of Flange Immersion Heaters for petrochemical industries with an innovative design.

Our product range focuses on small tank petroleum-based heating applications requiring low density < 2W/cm² solutions with a total power up to 40kW.


THERMOCOAX Immersion Heaters are designed for direct immersion in liquids such as :

  • Heavy fuel
  • Preheating fuel
  • Light diesel fuel
  • Standard diesel fuel
  • Machine oil
  • Mineral oil
  • Lubricating oil…

Also, for asphalt, tar and other heavy or highly viscous components.

To complete this range, our large offer of thermocouples allows us to be part of the main projects in petrochemical factories combining efficiency and safety:
