NM300-FF Build

2023 saw OSGS further refine their hugely popular nitrogen trailer. The refined design saw small changes to shorten assembly time but most importantly build on the simplification of components used. 

The focus was to identify and then remove any unnecessary complexity – which is hard when the design has already been subjected to this over years, however we succeeded in producing our most reliable unit yet. 

With now only a handful of moving parts (3 x auto drains and 2 valves), there is almost nothing to cause a breakdown.

The trailer is still housed in a 9ft box trailer (towable by a Toyota Hilux, Ford Ranger or similar) which is composite alloy box frame and alloy trailer frame with offroad wheels, tyres and suspension. The package consists of;

• 8 x membrane air dryers
• 4 stage OSGS filtration package
• 4 x OSGS nitrogen membrane modules
• Instrumentation such as flow meters, pressure and temperature transmitters, oxygen sensor and dew point monitor

Our trailers come road registered, with trailer braking system and brake away braking system along with off-road suspension, 4wd tyres and rims all integrated into an alloy frame for added weight savings – the entire package is approx. 1,600 kgs.

The nitrogen trailer is designed to take a feed of aftercooled air from any portable compressor, then treats and filters the air to the appropriate specifications – meaning from arrival on site, you can be pumping nitrogen using any available rented in compressor within 15 minutes. 

The system has strong inlet condition monitoring of feed air complete with alarms and shutdowns for system and process protection, all user configurable. The trailer operates in full automatic mode (flow or purity settings) or manual mode.

The NM300-FF continues to be one of the most popular packages OSGS has designed.
