THERMOCOAX manufactures rigid and flexible customised transfer line heaters for gas and liquids and heating nozzles to be integrated in analysis systems.

The small diameter of our heating cables allows us to design high density small heaters with fast temperature ramp-up and high homogeneity.

 When building a transfer line mounted between a gas chromatograph and a mass spectrometer, the heating element is mounted on the true cold end heater element and can be wrapped 2 wires in hand with a different pitch in order to ensure an homogeneous temperature all along the tube.

  • Stainless steel tube, vacuum brazed heaters with varying distribution to obtain temperature uniformity +/- 2°C along the full length
  • Hard-packed MI cable insulation allows the cable to be given virtually any shape without deterioration under working conditions
  • Thermocouple/RTD integrated for regulation
  • Manufacturing process fully controlled: traceability, subcontractor assessment, internal and external audits, regulation compliance
  • Standard working temperatures from 200°C to 850°C
  • Fully customised design for both THERMOCOAX ISOPAD heated hoses and THERMOCOAX transfer lines
  • Heater suitable to work with a low voltage 24VDC

With compact custom heating systems with integrated thermocouples and RTD, Thermocoax helps to solve key issues faced by the analytical industry today:

  • Lower thermal masses to avoid data loss
  •  Accurate temperature measurement
  • Faster temperature ramping
  • Smaller diameter heater for optimal thermal profiling
