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.
