OPTIIMAC Nitrogen Generator NM100 Series

This unit produces up to 3.6 nm3/hour of high-purity nitrogen from compressed air supply. It provides convenience and a significant cost savings, relative to using gas cylinders. Selective permeation through polymeric hollow fiber membranes separates nitrogen from other air components – there are no moving parts to make noise or wear out. Specifications – NM100-1-H40 Nitrogen Purity: > 99.99% Moisture:<0.5ppm Oxygen: < 100 ppm Halocarbons/Hydrocarbons: <2.0ppb Outlet Pressure: 60-100psig (4.2-7.0 Bar) Flow: 1-3.6 NM3/hour Inlet Air Requirement: Moisture: < 200ppm Hydrocarbons: <1.0ppm Particles: < 5 microns Inlet Pressure: 60-120psig (4.2-8.4 Bar) Dimensions (H x W x D): 852 x 1200 x 1500 mm Weight: 40 kg Outlet: 3 port x ¼" female NPT Control Power – 24 VDC , 0.5 KWH Microprocessor Base controller and LCD Interface Combined with Oil-free Air Compressor and Dryer One-year warranty from Polysource OPTIMAC.

Principal of Operation of Nitrogen Membrane Seperation. Polysource OPTIMAC NM100 Series – Nitrogen Generators utilize two different types of air preparation membranes to produce the required Gas outputs. The Nitrogen side of the generator employs “Hollow Fibre Membrane” Technology to efficiently separate Nitrogen from other gases present in ambient air. An overview of this process can be seen below.

The Zero Air side of the generator uses the latest technology in heatless desiccants dryers to produce a clean dry supply of Zero grade air. Both membranes and desiccants are mounted in a similar fashion in the generator and utilize standard ancillary components to maximize the interchangeability of the systems. The standard membrane diagram can be seen below.

Membrane - Standard Diagram Air is drawn into the system by the Compressor (1) and passed through the Cooling Coil (2) and Refrigerant Dryer the Micro Mist Filter (3) into the Desiccant Dryer (5). After the Membrane (5) the gas is passed through a Acting Carbon Filter (6) to remove any remaining impurities and via the Non-Return Valve (Check Valve) (7) into the Receiver (10). The stored gas is regulated (11) to give the required output pressure and flow. Receiver pressure is measured (9) to allow the generator to un-load (4) and shut-down should demand cease. A Safety Relief Valve (8) is fitted to protect the system against over pressure. Gas is analyzed for impurity and delivered out of the machine via the Outlet (12). Any moisture collected by the refrigerant dryer and Micro Mist Filter (3) is expelled via the Drain Port (13).
