Chamber Furnaces for Annealing, Hardening and Brazing

Laboratory


Chamber furnace N 7/H as table-top model	Chamber furnace N 61/H

Working with protective gas boxes for a protective gas atmosphere using a charging cart

To withstand harsh use in the laboratory, e.g. when heat-treating metals, robust insulation with light refractory bricks is necessary. The chamber furnaces N 7/H - N 87/H are a perfect fit to solve this problem. The furnaces can be extended with a variety of accessories, like annealing boxes for operation under protective gas, roller guides, or a cooling station with a quench tank. Even high-performance applications like the annealing of titanium in medical applications can be implemented without the use of expensive and complicated annealing systems.
