HEATING CABLES – HEATING SYSTEMS

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

THERMOCOUPLES & TEMPERATURE SENSORS

The essential part of THERMOCOAX construction is that both thermocouple conductors, insulation and metal protecting sheaths are combined as a cable.

This construction offers several advantages:

  • Small overall dimensions and high flexibility, which enable temperature measurements in locations with poor accessibility
  • High mechanical strength
  • Protecting the thermoelectric wires against oxidation, corrosion and chemical pollution
  • Very fast response time, which allows measurement of very short temperature variations.

Thanks to the highly compact insulating powder metallographic status of the conductors and sheath, the THERMOCOAX thermocouples are very flexible and may be bent to a radius equal to three times the outer diameter without causing any damage.

Our wide range of thermocouples offers many advantages in a wide range of applications.

  • Temperature response in accordance with IEC 584-1 and 2 / ASTM E 230 & 235
  • type J, K or N type, class 1
  • Type S, R or B for high temperature
  • TUS & SAT thermocouples for heat treatment applications
  • Very high temperature for 0°C to 2300°C applications
  • Sheath alloy: stainless steel, Inconel
  • Diameter: 0.25 to 6 mm
  • Length: no limitation
  • Easy shaping for better integration
  • ATEX certification upon request

In-house Calibration

In order to meet all calibration demands, THERMOCOAX has its own metrology department located at the production plant in Planquivon (France), accredited by the COFRAC Calibration Section under registration number: 2.1384 referring to calibration at fixed points of the thermo-electrical couples.

Because of their construction, dimensions and features, THERMOCOAX sheathed thermocouples can be mounted easily using adhesive, soldering, clamping, brazing, welding or seal glands.

We offer you the possibility of designing and manufacturing custom sensor solutions or complete thermal systems with mineral insulated cable heaters and sensors.
