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 quench cycle. Fortunately, Helium is one of the easier gases to reclaim after use.
A key to ALD Vacuum Systems 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.
The recycling takes place in conjunction with the balance of the heat treating system making certain the gas is ready for each quench when necessary. This is controlled automatically through the furnace control system and requires no operator intervention. It couldn’t be simpler.
The reclaimation system is compatible with our DualTherm® and ModulTherm® furnace systems.
YES! We can also recycle Argon quench gas at 99.5% per quench. Additionally, if you’re located in Mexico, we can help you with recycling nitrogen because of the exceptionally high prices in there it can make sense.
