PR CCH Series Muffle Furnace

Retort furnaces for inert or reactive atmospheres up to 1150ºC.CRN Series (Large Capacity)


The HCV CCH models are retort furnaces with hermetic seal that allow working with modified atmosphere (Inert or reactive). Furnace chamber and door made of Inconel refractory steel with hermetic seal thanks to a water-cooled silicone gasket (NBR) on the front panel and door.

Hot wall retort
Allows primary vacuum (1Mbar).
Suitable for metal and ceramic sintering for 3D printing, implants, welding… any heat treatment that requires the absence of oxygen to avoid oxidation.
Special applications such as inert debinding or pyrolysis processes.
