Camco Furnace's coldwall hydrogen and high vacuum equipment

Camco Hydrogen Furnaces

By operating in hydrogen or any reducing/inert atmosphere up to 2100°C, Camco's positive pressure coldwall furnaces are an ideal solution to many high temperature processes that require an oxygen-free or reducing environment. Easily and reliably ramp up to the desired temperature in minutes or days, depending on your requirements. Additionally, optional heated bubblers and dewpoint monitors can be used to easily achieve and control the higher dewpoints necessary for metalizing ceramics. Most of our models will roll through a standard interior door frame with little to no deconstruction. All our furnaces are fully automatic. One button push performs:

→ Purge (Fully evacuate with vacuum pump, and displace atmosphere inside chamber with nitrogen)
→ Process gas fill with mass flow controller (H2, N2, or mixture)
→ Bubbler for humidification of process gas (Optional)
→ PID controlled ramp(s) to target temperature
→ Soak
→ Cooldown
→ Post purge (displace process gas inside chamber with nitrogen for safe opening)

Hydrogen furnaces offer a lower cost alternative to high-vacuum furnaces if the process can allow for it. They are self cleaning, inexpensive to run and maintain, and process cooling in hydrogen is quick and controllable.

Though built specifically to run safely in a wet or dry hydrogen atmosphere, these furnaces can run just as well in any high-purity inert or reducing gas types such as:

•Forming Gas (H5N)
•Dissociated Ammonia
•or any combination.
