Solutions for the Furnace industry

An industry leader

For more than 70 years, Conax Technologies has been a leader in the design and manufacture of compression seal feedthroughs, temperature sensors and cable and harness assemblies for a broad range of industries, including solutions 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

ISO/IEC 17025:2017 accreditation

Conax Technologies’ calibration laboratory is ISO/IEC 17025:2017 accredited. ISO/IEC 17025:2017 sets the national standard of excellence for the competence of testing and calibration laboratories. This accreditation officially recognizes Conax as fully capable and competent and assures customers that our lab will produce valid and reliable results.

AMS 2750 compliant sensors

Conax supplies sensors in compliance with the latest AMS 2750 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).

Precious Metals Reclamation

Conax Technologies manufacturers, and offers reclaim credit for, platinum/rhodium precious metals thermocouples. These are commonly called Type-S, Type-R or Type-B thermocouples. To send either thermocouples or precious metals wire to Conax for reclaim, you must first contact Conax to issue an RMA (Return Materials Authorization) number to you. When we receive your shipment, we will disassemble, remove and weigh the wire. We will then calculate the value based on the current market pricing of platinum and rhodium. This value is given to the returning company in the form of a credit to apply against current or future invoices. Please contact your Conax sales person for more details.

Solutions for Providing Electrical Input

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.

Temperature Sensor Solutions

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:

Instrumentation Feedthrough Solutions

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:

- Multiple probe or wire seal fitting
- Compression seal fittings for vibration sensors, humidity sensors, pressure sensors, control sensors, and more
- Single probes or sensors
- Split fittings for sealing on cables/wires with connectors or sensors larger than cable diameter (SPG & DSPG)
