Our PSA Nitrogen Generators are built using advanced CMS through a technical collaboration with CarboTech, Germany — pioneers in narrow-pored CMS production. Their precision-engineered pore structure enables efficient separation of oxygen and nitrogen molecules, ensuring consistent purity up to 99.9999% and long service life of the system.
Nitrogen requirements change by process. A food packaging line, SMT facility, petrochemical plant, and heat treatment furnace may all need nitrogen, but the right generator depends on purity, flow, pressure, duty cycle, and operating conditions.
What nitrogen solves
Reduce oxygen exposure for packed food, oils, beverages, and stored materials.
Create oxygen-controlled atmospheres for electronics, metals, and heat treatment.
Displace air and oxygen from tanks, pipelines, reactors, and LNG systems.
Maintain repeatable purity, pressure, and flow for continuous industrial operation.
Shelf life and oxidation control
On-site nitrogen for modified atmosphere packaging, edible oil processing, wine production, beverage dispensing, controlled atmosphere storage, and bulk storage blanketing.
Nitrogen role
Sizing basis
Residual oxygen, line or room demand, operating hours
Regulated and oxygen-sensitive production
On-site nitrogen for API reactors, pharmaceutical packaging, vial and bottle purging, tank blanketing, lyophilization support, and moisture-sensitive storage.
Nitrogen role
Sizing basis
Purity or O2 target, use-point pressure, documentation
Clean, oxygen-controlled production
High-purity nitrogen for SMT soldering, PCB protection, battery manufacturing support, wafer handling, and sensitive electronics production.
Nitrogen role
Sizing basis
O2 ppm, line count, flow stability
Inerting, purging, and process safety
Nitrogen generation for tank blanketing, reactor inerting, pipeline purging, catalyst protection, polymer processing, and hydrocarbon safety systems.
Nitrogen role
Sizing basis
Purge volume, hazard zone, batch or continuous duty
Protective atmospheres and heat treatment
Reliable nitrogen supply for annealing, heat treatment, laser cutting, galvanizing, cement plant inerting, LNG tank purging, and protective atmospheres.
Nitrogen role
Sizing basis
Furnace volume, pressure, atmosphere composition
