Hood furnaces from ENA – Flexible industrial furnaces for demanding heat treatment processes
Bell furnaces are among the most versatile and adaptable industrial furnaces, especially when it comes to variable loading concepts and individual process requirements. A typical feature of a bell furnace is the flexible loading option – depending on the design, the furnace chamber can either be closed from above with a lowerable hood, or the furnace floor itself can be raised or lowered. This modular design allows for optimal adaptation to workpiece geometries, cycle times, and automation concepts.
Different opening mechanisms – tailored to your process
Our bell furnace systems are available with various opening mechanisms, depending on the desired automation, accessibility and design:
Pneumatic hood opening: For automated processes with minimal operator intervention
Mechanical hood lifting: Either the hood moves upwards or the furnace floor moves vertically – ideal for high
Loads or precise positioning
This flexibility makes our bell furnaces the ideal solution for applications requiring reproducible temperature control and fast loading and unloading – for example, during annealing, sintering, preheating, or heat relaxation.
High-temperature hood furnaces – powerful in all temperature ranges.
Our hood furnaces for industrial applications cover a wide temperature range:
Standard operation: 150 °C to 1,450 °C – suitable for most heat treatment processes in air or controlled atmosphere
Special furnaces: 1,550 °C to 1,850 °C – for high-temperature applications under protective gas, e.g., in sintering technology, ceramic processing, or powder metallurgy
Depending on requirements, our bell furnaces can be equipped with additional insulation, multi-zone heating, or integrated cooling. They can also be combined with continuous furnaces or vacuum furnaces—for example, in a multi-stage heat treatment line.
Your advantages with a hood furnace from ENA
Our industrial bell furnaces are available in a wide range of sizes, power levels, and levels of automation. Depending on the application, you can choose from:
Flexible loading options
