Nitrogen Generator Maintenance Services
Advanced Gas Technologies (AGT) provides professional maintenance services for Pressure Swing Absorption (PSA) and membrane nitrogen generators across North America, backed by 24/7 emergency support and more than 30 years of hands-on experience with industrial nitrogen generation systems.
Regular, scheduled maintenance is what keeps an onsite nitrogen generator operating at the purity level and flow rate your process depends on. Left unaddressed, small maintenance gaps lead to purity drift, unplanned downtime, and accelerated component wear. A structured preventive maintenance program eliminates that exposure. If your nitrogen generator is underperforming or overdue for service, contact us to schedule an assessment.
Nitrogen Generators We Maintain
AGT maintains and services both PSA and membrane nitrogen generation systems. Our technicians are trained and experienced on each technology, including the distinct maintenance requirements that apply to each.
Because PSA systems contain multiple automated switching valves, solenoids, and a PLC control system, they require more structured maintenance than membrane units. With proper maintenance, a PSA generator can operate reliably for 20 or more years.
Membrane systems have fewer moving parts and a lower overall maintenance burden.
For both PSA and membrane systems, their long-term performance depends directly on compressed air quality. Oil or moisture in the feed air will degrade performance over time, making compressed air pre-filter maintenance the single most critical service task.
Our Nitrogen Generator Maintenance Services
AGT provides a full range of maintenance services to keep your nitrogen generation system operating at the purity and flow rate your process requires, with minimum disruption to your operations.
Preventive Maintenance Contracts
A preventive maintenance contract is a scheduled service agreement under which our technicians visit your site at defined intervals to perform all required maintenance tasks, log system condition, and identify any components approaching the end of their service life. Our preventive maintenance contracts include system inspection, compressed air pre-filter replacement, purity verification, pressure checks, and more.
24/7 Emergency Service Support
AGT provides 24-hour service support for nitrogen generator systems across North America. Our service network extends through a global network of industry partners, giving us the reach to support systems in most regions. Our service includes fault diagnosis, system inspection, parts supply from our maintenance and service spares inventory, and on-site repair.
Switching Valve Inspection & Replacement
A malfunctioning switching valve reduces nitrogen production efficiency and, if left unaddressed, can allow contamination to reach the CMS beds. Our technicians inspect valve operation, check for signs of seat wear or seal failure, and replace components as required.
Compressed Air Pre-Filter Replacement
Our technicians replace coalescing, carbon, and particulate filter elements according to manufacturer-specified intervals, inspect automatic drain valves and filter housings, and verify the compressed air entering the generator meets the inlet quality requirements of the system.
Nitrogen Purity Monitoring
AGT technicians verify nitrogen purity at each maintenance visit, calibrate oxygen analyzers, and replace analyzer sensor cells on the manufacturer-recommended schedule. For systems operating at lower purity levels, analyzer calibration can be performed using compressed air as the reference gas. High-purity systems require calibration gas. Accurate purity data is the foundation of any effective maintenance program.
System Pressure Checks & Leak Inspection
Addressing a small leak or a pressure anomaly at a scheduled maintenance visit costs a fraction of what an unplanned emergency shutdown costs. Our team will check operating pressures across the system, inspect for leaks at connections, fittings, and valve bodies, and verify that the nitrogen generator starts, loads, and goes into standby as designed.
Maintenance Training
AGT provides operational training for facility personnel covering correct startup and shutdown procedures, daily purity and pressure checks, compressed air receiver inspection, and the early warning signs that indicate a service call is needed. Operators who understand what normal system behaviour looks like are the first line of detection for developing issues.
Why Choose Advanced Gas Technologies
AGT has been installing, maintaining, and servicing onsite nitrogen generation systems in North America since 1994. Our technicians have serviced systems across a wide range of industries, applications, and operating conditions. We maintain the systems we design and install, and we also service nitrogen generators installed by other manufacturers. Whatever system you are running, our technicians can assess its condition, bring it to spec, and put a maintenance plan in place that matches your production requirements.
Frequently Asked Questions About Maintaining Nitrogen Generators
How often does a nitrogen generator need professional maintenance?
The recommended service interval for most nitrogen generators is every three to six months, depending on the system type, operating hours, and the compressed air quality at your site. PSA nitrogen generators require attention to filter elements, oxygen analyzer calibration, and periodic switching valve inspection. Membrane nitrogen generators require pre-filter maintenance and membrane integrity checks. Always follow the manufacturer's recommended maintenance schedule. Your system manual will specify the intervals that apply to your equipment.
What does a nitrogen generator maintenance visit from AGT include?
A typical AGT maintenance visit covers compressed air pre-filter inspection and replacement as required, nitrogen purity verification, oxygen analyzer calibration, system pressure checks, leak inspection, valve operation review, and a logged inspection report. For PSA systems, switching valve condition is assessed at the intervals appropriate to operating hours. For membrane systems, membrane condition and inlet air quality are reviewed. You receive a documented record of what was inspected, what was replaced, and what the system's next service requirements are.
What are the warning signs that a nitrogen generator needs service?
The most common indicators that a nitrogen generator requires attention are:
- A purity reading that has dropped from the level recorded at commissioning
- Pressure readings outside normal operating parameters
- Unusual sounds during valve cycling
- Visible moisture or oil in the compressed air filter housings
- Maintenance advisory messages on the system display
- A failure to start up and go into standby as normal.
Any of these conditions warrants a service call rather than continued operation.
Do you service nitrogen generators that AGT did not install?
Yes. AGT provides maintenance and service for nitrogen generators regardless of manufacturer or installer. If you have a PSA or membrane nitrogen generator that is underperforming, overdue for service, or of unknown maintenance history, we can assess the system, bring it back to operating specification, and set up a preventive maintenance program going forward.
