N 120/65 HACDB - N 500/65 HACDB

The air circulation chamber furnaces N 120/65 HACDB - N 500/65 HACDB are perfectly suited for debinding processes that require a good temperature uniformity due to the parts geometry or characteristics of the binder. The powerful, horizontal air circulation with high air flow rate provides for full utilization of the furnace in different charging layers. Uniform process results are ensured even for small components, such as CIM manufactured parts. On request, the furnaces can be equipped with catalytic or thermal afterburning to clean the exhaust gases. Following the debinding the components are transferred to the sintering furnace.
