NITROSource PSA and NITROSource Compact provide a very safe, cost effective and convenient source of gaseous nitrogen.
When considering system design, and installation, there are a few points to consider to ensure a trouble free operation and long service life.
Please refer to the appropriate user manual for full installation instructions.
OFAS or OVR grade activated carbon filtration recommended and is required for operation above 35°C

Parker NITROSource and NITROSource Compact are IP20 rated and therefore designed to be installed indoors or within a protective housing such as a modified ISO container.
The compact size enables siting in quite confined areas although consideration needs to be given to allow for service access and pipework connections.
Because the nitrogen generators vent oxygen enriched nitrogen during certain periods of the operating cycle, adequate ventilation is essential. Further information on this is available from your local Parker resource.
Because the generators are constructed mainly from aluminium extrusion, a material extremely efficient at conducting heat, the ambient air temperature is of greater consideration than the compressed air approach temperature. The minimum and maximum ambient operating temperature range is from 5 to 50oC (41 to 122oF).
The nitrogen generators are able to operate from a standard factory, oil lubricated compressed air supply, ideally a variable speed drive, rotary screw type.
The pressure range is from 5 to 13 barg (72.5 to 188.5 psig) barg for NITROSource and 5 to 10 barg (72.5 to 145 psig) for NITROSource Compact.
The compressed air can be supplied from a centralised factory compressor or dedicated unit.
Suitable pipework materials for the compressed air supply to the nitrogen generator would typically be medium weight threaded galvanised or the preferred option is blue coloured Parker Transair.
The nitrogen pipework, to and from the buffer as well as to supply the application is recommended as green Parker Transair for purities up to 50 ppm and for purities below this at 10 ppm and 5 ppm, table “X” de-greased brazed copper or welded stainless steel is recommended.
Isolation valves are also necessary to enable servicing and disconnection when required. Please refer to the appropriate user guide for full details before installation.
NITROSource PSA and NITROSource Compact require clean, dry, oil-free compressed air to operate correctly.
The exact specification for the inlet compressed air depends on certain factors relevant to the application and customer requirements.
Parker manufactures full pre-treatment packages covering refrigeration, hybrid, and desiccant drying technology as well as particulate and oil vapour reduction filtration.
For most applications refrigeration drying technology with the appropriate particulate and OVR grade filtration is sufficient. With the correct product selection, installation, operation, and service plan in place the nitrogen generator qualifies for 1+4 years warranty.
Where desiccant drying technology is specified along with the appropriate particulate and OVR grade filtration, 1+9 years warranty is available covering the CMS and pressure envelope. As well as the 1+4 year warranty on the other specified components.
To activate the 4 years’ extended warranty customers must register their purchase online, within 180 days of the invoice, at polewr.com
