VAC AERO’s IG Series Quench Gas Storage Systems are available as an option.
IG GAS SUPPLY SYSTEMS
In vacuum furnace applications where rapid gas quenching is required (for example, heat treating of air hardening tool steels or high speed steel) it is important that the furnace chamber be backfilled very rapidly with inert gas. It is also important that this gas be supplied to the furnace without contamination. When the product processed in a vacuum furnace is discoloured or contaminated it is often a result of contaminated quench gas.
The IG Gas Supply Systems built by VAC AERO are sized to supply quench gas to the furnace chamber so that it can be backfilled in 30 seconds or less. The system also includes back flow, purge and safety devices to ensure the purity of the quench gas. The system is designed to be supplied from high pressure bulk gas storage or liquid storage (cold converter) sources.
The IG tank is an ASME approved receiver, which at an internal gas pressure of 120 psig will supply a sufficient volume of quench gas to backfill the chamber to two bar in 30 seconds or less. The tank can be supplied in vertical or horizontal configurations.
