Bell Jar Loading Furnaces

Oxy-Gon’s Bell Furnace is designed to provide years of continuous service for applications involving movement sensitive loads.

For delicate parts and loads that have a high sensitivity to movement, Oxy-Gon has designed the ideal solution with our BF Series Bell Furnace. With the most sensitive loads in mind, our bell-style furnace has been designed for optimal performance and ease of use. It features a stationary bottom hearth used for staging the load, which is then combined with a chamber that is lowered over the product and clamped in place to ensure completely uniform heating.

The BF Series Bell Furnace is designed to optimize space, performance, and flexibility for a wide variety of heat treating, laboratory, and production applications. Moreover, with its minimal particulate contamination, it’s the perfect choice for semiconductor production or applications involving medical devices.

The basic Bell Furnace system includes the furnace assembly, power supply, heat zone, and evacuation system.

Applications for the BF Series Bell Furnace include:



Diffusion Bonding

Ceramic Firing


Glass Processing Studies



Carbon Glass & Ceramic Composites
