Nitrogen Generator (Membrane) · Inert Gas Systems
Parker Hannifin Marine N2 Membrane N2-500 99% is a nitrogen generator (membrane). It is installed in the tanker inert-gas or nitrogen plant and connected to the cargo-tank gas distribution system. Its purpose is to generate, clean or condition low-oxygen gas for cargo-tank inerting and atmosphere control according to the installed process. Gas-generation, scrubbing or membrane or PSA stages, blowers, valves, analyzers, drying and control interlocks form the process according to the exact design. The exact model designation distinguishes gas capacity, process method and purity from neighboring inert-gas or nitrogen units; refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect process vessels, scrubbers, membranes or adsorbers, fans or compressors, valves, analyzers and pressure-control equipment. Remove soot or deposits and maintain free drainage where wet gas treatment is used. Verify oxygen or process analyzers using the approved calibration method and keep sampling lines clean. Function-test alarms, automatic shutdowns and deck-isolation arrangements as required by vessel procedures. Inspect corrosion-prone wet sections and pressure vessels closely. Refer to the manufacturer documentation for the exact figure for oxygen, purity, pressure, temperature and maintenance limits.
Keep filter or demister elements, fan or compressor seals and bearings, valve service kits, analyzer cells or sensors, gaskets and manufacturer-recommended control spares. Membrane or adsorbent replacement should follow the exact process design. Confirm materials are compatible with the installed gas service.
