Air circulation furnace with protective gas box

N 30/45 - N 500/85HA

Due to its high temperature uniformity, these chamber furnaces with air circulation are suitable for processes such as tempering, quenching and tempering, precipitation hardening/curing, solution annealing, artificial aging, preheating or soft annealing and brazing. The furnaces can be equipped with suitable protective gas boxes for soft annealing of copper or tempering titanium as well as tempering of steel in a protective gas atmosphere. The modular design of the furnaces allows accessory equipment to be added based on process requirements.
