Furnace & Autoclave
Description
Engineered Solutions for the Furnace and Autoclave Industry
For more than 50 years, Conax Technologies has served as a leading source of temperature sensor and pressure/vacuum sealed fittings feedthroughs for the Furnace and Autoclave Industry. Our temperature sensors and fitting/feedthrough assemblies are installed in various equipment types such as furnaces, ovens, kilns, autoclaves, freeze-dryers, vacuum furnaces, etc. Conax has various standard products for each of these equipment types but also has the capability to custom design a solution for any application or equipment. Feel free to contact our Autoclave Application Engineers today to discuss your application.

Providing Power
Conax Technologies sensors and seals are used in various processes in the Furnace and Autoclave Industry. From monitoring product temperature in sterilization chambers to providing power to a fan or heater, Conax has a solution for you. Our products are commonly found in processes such as sterilizing, curing, heat treating, glass laminating, vacuum processing, vulcanizing and many more. Describe your process to our application engineers and they will design a standard or custom solution.
If you need to provide power 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.
