Solutions for the Furnace industry

An industry leader

For more than 60 years, Conax Technologies has been a leader in the design and manufacture of temperature sensors and compression seal feedthroughs for furnaces used in the steel, aerospace, heavy industrial, and automotive industries.

Conax customers rely on our standard and custom-designed solutions for a variety of processes, including melting, casting, re-heating, annealing and coating.

Sensors and seals for a wide range of furnaces

Our temperature sensors and fitting/feedthrough assemblies are used in various types of furnaces, ovens and kilns across a variety of industries and applications, including:

  • Steel and metal production
  • Glass manufacturing
  • Heat treating parts and components
  • Ceramic manufacturing, cement and brick plants
  • MIMs for load thermocouples
  • Platinum control thermocouples

AMS2750E compliant sensors

Conax supplies sensors in compliance with AMS2750E calibration requirements. And we manufacture base metal thermocouples, such as types K, N, E, J and T, that can withstand operating temperatures up to 2300ºF (1260ºC). For high temperature applications, Conax manufactures noble metal and refractory metal TCs, including types S, R, B and C, that can withstand temperatures up to 4200°F (2315°C).

If you need to provide electrical input to a fan, motor, heater or other AC or DC powered device, Conax has two great solutions covering virtually any power feedthrough requirement. Our power series compression seal fittings are simple and reliable mechanical pressure and vacuum seal fittings to supply high voltage or current to your equipment and protect your environment.

Single Electrode Style Compression Seal Fittings—Our single electrode style compression seal fittings allow for up to 525 amps per single electrode at up to 8000 VDC. Products include:

Power Lead Style Compression Seal Feedthroughs—Our Power Lead (PL) compression seal feedthroughs provide multiple sealed, insulated wires for inserting power into a furnace.

Conax Technologies is the industry leader in the design and fabrication of temperature measurement devices. Conax temperature and control sensors are used throughout the furnace industry in a variety of processes. Our products include:

Conax Technologies’ sealed feedthroughs and compression seal fittings have proven to be the industry leaders in quality and performance. We’re the originators of soft sealant technology that, when combined with mechanical compression, results in a remarkably secure seal on wires, probes, and electrodes passing through a pressure or environmental boundary. The solutions listed below are commonly used in furnaces.

Feedthroughs with factory-installed lead wire are available in copper or thermocouple wire and include:

Feedthroughs without factory-installed lead wires include:
