Helivac

… the economical alternative to new investments

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

Characteristics:

• Increase of quenching speed of existing vacuum furnace
• Reduction of distortion up to 50%
• Repressurizing rates of used helium > 97%
• Short repressurizing rates
• Duplication of quenching speed by the 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 at stable hardening distortion
• Easy to maintain due to optimized design of unit
• Less space required
• One system can be used for various furnances
