Vacuum Furnaces PR-V Series 

Vacuum and modified atmosphere furnaces for metal sintering (3D additive)


The PR-V models are vacuum furnaces from x10-2 mbar up to x10-5 mbar and modified atmosphere that allow working in atmosphere and vacuum in the same process. 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. (Retort furnace)

Hot wall retort

Allows vacuum up to 1150ºC.

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 sintering processes.
