CZA-4N-2 Ultra-High Purity Purifier (dual pre-adsorption towers + downstream high-temperature alloy N₂-removal tower)
Ultra-High Purity Purifier (N₂ Removal) CZA-4N-2
Overcomes the industry bottleneck where conventional purifiers cannot remove nitrogen impurities from inert gases, achieving residual N₂ as low as 0.2 ppm.
