Nitrogen Production Units (NPU) - Mobile and Portable N2 Generator
You need a mobile and reliable solution for your remotely located nitrogen application or you need a large quantity of nitrogen only for a limited period of time?
Then you should consider the proven Nitrogen Generation Units (NPU) from NOXERIOR. Their rugged design allows a fast mobilization and installation at any location without the need for substantial site preparations.
Advantages of NPUs from NOXERIOR
- Rugged design, proven quality & reliability
- Superior efficiency
- No need for external feed air receiver and feed air dryer
- Suitable for operation at both desert and artic ambient conditions
- External easily accessible tie-in points, but protected against eventual transport damage

Technical Specifications
A NPU from NOXERIOR is a membrane nitrogen generator, turn-key installed inside an ISO freight container, including all necessary system components and controls to start nitrogen production by a simple push-button:
- Air-cooled after-cooler for incoming feed air
- Cyclone separator or demister for bulk condensate removal from incoming feed air
- Feed air filtration, including an activated carbon tower;
- Moisture analyser;
- Electrical feed air heater with thyristor capacity control
- Automatic off-spec feed air blow-off
- Set of hollow-fibre membrane modules
- Nitrogen flow control
- Residual oxygen analyser,
- Thermal or coriolis nitrogen mass flow meter
- Automatic off-spec nitrogen blow-off
- Local pressure and temperature transmitters
- PLC based control system with IP/Ethernet connection for fully automatic and unattended operation of the NPU on a 24/7 operating basis
- Automatic purity adjustment between 7,0 and 0,5 vol.% of residual oxygen
- Room oxygen analyser and smoke detector with external visual and acoustic alarm
- Thermostatically controlled room heater / forced ventilation with intake filters and automatic louvers
- Externally accessible junction box for central power supply
- External flanged tie-in points for feed air supply and nitrogen discharge
- All pressure vessels designed and certified to EN 13445 and 97/23/CE (PED)
On request, NOXERIOR can also supply you an electric or diesel-driven air compressor for the required feed air supply. Depending on its size , the air compressor will be either integrated inside the ISO container or mounted on a separate ISO transport frame. A separated feed air receiver or separate air dryer are not required for NPUs from NOXERIOR.
