Helium Gas Quench Recycling


Helium provides the most quenching capability when high pressure gas quenching in a vacuum furnace.  Its physical characteristices give it superior properties that are beneficial to the heat treater and encroach well into the oil quenching realm. 

However, considering the high price of helium and its’ rarity, it is financially unrealistic and environmentally irresponsible to simply vent it to atmosphere at the completion of a vacuum furnace quench cycle.  Fortunately, Helium is one of the easier gases to reclaim after use.

A key to ALD-Holcroft high pressure gas quenching technology is our patented helium recycling system.  It makes the use of Helium as a quench media not only possible but cost effective, by reclaiming 99.5% per quench sequence.

The recycling takes place in conjunction with the balance of the heat treating system making certain the gas is ready for quench when necessary.  This becomes invisible to the operator since it is tied to the furnace control system.  It couldn't be simpler.

The reclaimation system is compatible with our single chamber vacuum furnaces called MonoTherm, our two-chamber vacuum furnaces called DualTherm and of course are integral to the success of our multi-chamber furnace systems called ModulTherm.




YES!  We can also recycle Argon; 99.5% per quench!
