Pit vacuum furnaces are ideal for processing vertical axis parts. Its reduced footprint and its design makes it a highly economical solution for investment.

Rubis range offers economical solutions for low pressure heat treatment, with gas quenching for vertical axis parts. Its simple structure makes it a robust solution with low maintenance costs.


Main advantages include:
Removable top easing loading and unloading phases of large size parts
Full graphite insulation and heating element
Accelerated cooling system by gas injection ensures homogeneous diffusion on loads during cooling phases, while reducing cycles times.
