Further Details:

EnerMech, a leading oil and gas services company have taken delivery of another 3 of our 4000 scfm 24 bar nitrogen containers in 2021 – model NM4000-HP.  Designed and built in our Sydney plant.

The containers, each delivering 4,000 CFM nitrogen at 95% at 350 PSI and are integrated into a custom built DNV offshore certified container.

The packages were designed and built by On Site Gas Systems in Sydney in 2021 and incorporated some last minute additional functionality that the customer wanted and OSGS was able to quickly adapt and provide for those requests.

NM4000-HP at a glance;

  • Built into a 20ft DNV certified off shore container for offshore operation
  • Capacity of 4,000 CFM nitrogen at 95%
  • 350 PSI (24 bar) working pressure
  • 5 stage high pressure filtration package
  • Glycol based air heating system
  • OSGS high pressure membranes


The containers are dual power with the option of 240 V AC or 24 V DC power supply, utilise glycol for the pre-membrane air heating, have fully automated control based of flow or purity, house inlet and discharge flow meters and have job flow counters for nitrogen pumping measurement, process oxygen sensors, 2 internal cabin O2 sensors along with a range of instrumentation for measuring pressure, temperature and dew point for various inlet condition and outlet condition monitoring.
