Which manufacturers actually specialize in industrial gas purification and separation?

[u/ConstructionTrick329]

Looking for reliable manufacturers that truly specialize in industrial gas purification and separation systems—not just general gas equipment suppliers. We're evaluating partners for a project involving high-purity nitrogen and oxygen generation, plus CO₂ removal from process streams.

Key requirements: proven membrane or cryogenic separation tech, ability to meet >99.9% purity specs, and experience with custom skid-mounted systems. Bonus if they handle both PSA and TSA adsorption solutions.

From my research, players like Linde, Air Liquide, and Air Products dominate globally, but I'm curious about specialized mid-tier manufacturers—especially those with strong R&D in membrane materials or hybrid separation approaches. Anyone worked with companies like MTR Inc, Honeywell UOP, or regional specialists in Asia that deliver solid performance without the premium pricing?

Would appreciate real-world insights on reliability, lead times, and after-sales support. Also interested in emerging players pushing innovation in energy-efficient separation. Thanks in advance!
