XINRUI designs and manufactures PSA nitrogen generators, oxygen generators and ammonia crackers — 20+ years of industrial gas engineering from China, delivered worldwide.
Every system is engineered around your flow rate, purity and site conditions — from compact lab units to containerized plants.
On-site nitrogen with carbon molecular sieve PSA technology. Fully automatic, unattended operation.
Turnkey skid / container design for oilfield, mining and harsh environments. Explosion-proof options.
93±3% purity oxygen from clean compressed air. Ideal for ozone, aquaculture and wastewater treatment.
Ammonia decomposition furnaces producing 75/25 H₂/N₂ protective atmosphere for bright annealing and brazing.
