Industrial Furnace
Bell-Type Furnace – Flexible Heating & Cooling 260–1300 °C
High Flexibility Through Separate Heating and Cooling
The bell-type principle separates heating and cooling spatially: a mobile heating bell (upper main chamber) is placed onto the batch and heats it, while a second batch cools in the lower cooling base unit (with forced air cooling). Maximum utilisation efficiency.

Frequently Asked Questions
What is the advantage of the bell-type concept?
The heating bell can be quickly moved from one base to the next, enabling very efficient operation with short idle times and high throughput.
What working volumes are available?
Bell-type furnaces are built with 1,000 to 10,000 litres of working volume. Sizing follows charge weight, component dimensions and required throughput.
How does cooling work?
The concept separates heating from cooling: once the hold time ends, the heating bell is lifted off and the charge cools under the cooling chamber – leaving the heated part of the plant free for the next batch.
Which processes is the bell-type furnace used for?
Primarily coil annealing of coils and rings, recrystallisation annealing and normalising in the 260–1300 °C range.
