BGT Nitrogen Production Unit receives compressed air at a minimum inlet pressure of 175psi (12bar), then separates the oxygen from the compressed air.

The air separation process is performed using B.G.Technical Limited membrane modules that are contained within the NPU. Each module is constructed of millions of hollow fibers like the diameter of human hair. Compressed air is forced through the hollow fibers.

The holes in the modules are small enough that CO, CO2 and O2 will exit through them under pressure. These small holes, however, are too small to accept N2 or Argon. B.G.Technical Limited NPU is ideal for remote locations and offshore platform.
