APSA™ onsite nitrogen generators are a good alternative to replace or dilute natural gas or ammonia-based atmospheres used for powdered metal sintering processes. The APSA™ technology utilizes fractional distillation of air to produce cryogenically pure nitrogen gas, the highest purity available (much higher than PSAs) without the use of hydrogen. For monthly volumes in excess of six million standard cubic feet, the modular systems offer one of the most reliable on-stream production in the industry and can provide one of the best and most economical solutions to nitrogen needs.
