Introduction
The Donaldson Nitropac Generator is designed to cater for a wide variety of industrial and
scientific applications. Your generator will have been carefully selected to meet your specific
pressure, flow, and purity requirements, if you have any questions regarding the sizing of your
system please do not hesitate to contact Donaldson.
Technical Description
Basic concept
A modular range of Carbon Molecular Sieve (CMS) nitrogen gas generators. The generators
operate using Pressure Swing Adsorption (PSA). This is where the product contains two separate
containers or “beds” of granular carbon pellets.
The unit requires a compressed air supply to operate, ultimately it is akin to many standard air
filtration / drying products. The inlet compressed air is passed into the first “bed”, as the air
passes across the carbon bed the oxygen is adsorbed, allowing the nitrogen in the compressed
air to carry on through the bed for collection and further use. After a certain time the online bed of
carbon will become saturated with oxygen. At this point in time, the control system will operate
various valves to bring the second bed of carbon on line. As the second bed comes on line the
first bed is vented to atmosphere to release the adsorbed oxygen and regenerate the bed ready
to be re-used again. This cycle will continue to repeat until the user stops consuming nitrogen.
Should the demand for Nitrogen be less than the rated output flow, or indeed should the demand
stop the generator will automatically go into ECO Mode and the front panel LED will illuminate. In
ECO mode the changeover of the columns is suspended which will stop the consumption of inlet
compressed air. The control system will automatically detect when the demand for Nitrogen
resumes and the generator will start to produce Nitrogen again.
