Helivac upgrade system


The economical alternative to net investments

Qualitative and economical upgrade of one-chamber vacuum furnaces (N2, 6-10bar) with quenching and repressurizingsystem HELIVAC due to enlargement of process spectrum and reduced distortion

System characteristics:

  • Increase of quenching speed of existing vacuum furnace
  • Reduction of distortion up to 50%
  • Repressurizingrates of used helium > 97%
  • Short repressurizingrates
  • Duplication of quenching speed by use of helium and increase of pressure from 6 to 10 bar
  • No constructive modifications on vacuum furnace necessary
  • Optimized hardening results due to increased quenching speeds atstable hardening distortion
  • Easy to maintenance due to optimized design of unit
  • Less space required
