From cryogenic temperatures up to 1000°C

Thermocoax heating cables consist of one or two straight current-carrying cores in a flexible metal sheath, electrically insulated from one another and from the sheath by means of a highly compacted refractory powder.

Thermocoax developed a special cold-end construction to cope with the problems of high heat density dissipation. These ends can be fitted with connectors.

Thermocoax heating cables offer a continuous sheath without joints or with a flush contour around the hot/cold transitions.

By combining small diameter and hard-packed insulation, our heating cables can take on virtually any shape without deterioration of either the insulation or the sheath.

Our thermal solutions can be used in air, under vacuum or high pressure and in most corrosive environments, depending on the sheath material.

To improve heat contact and thus heat transfer, the cable can be deformed, brazed or welded into its optimum position.

Easy fitting

  • Minimum bending radius: 3 x OD
  • Thermocoax heating cables can be attached directly to metal parts
  • The heat can be generated exactly where it is required, thus power losses are reduced, as is power consumption.
  • Excellent heat exchange: the heater can be brazed onto any metal piece

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:

  • Multipoint sensors
  • Hot point detectors
  • Specific sensors for subsea applications
  • Customised sensors

Thermocoax thermocouples are available with high-resistive sheath materials that can resist corrosive environments.

All temperature sensors can be operated inside pressure vessels.

THERMOCOAX thermocouples can be used in ATEX zones.

THERMOCOAX and ISOPAD solutions cover the primary needs of the petrochemical industries with electrical heating cables and solutions designed by our engineers.  All our solutions are customised to respond specifically to the customer’s needs.

  • Immersion heaters
  • Drum heaters
  • Reactor heater solutions
