The very good temperature uniformity of these chamber furnace with air circulation provides for ideal process conditions for annealing, curing, solution annealing, artificial ageing, sintering of PTFE, preheating, or soft annealing and brazing.
The forced convection chamber furnaces are equipped with a suitable annealing box for soft annealing of copper or tempering of titanium, and also for annealing of steel under non-flammable process gases. The modular forced convection chamber furnace design allows for adaptation to specific process requirements with appropriate accessories.
