DB Series Nitrogen Generator DB5-20 Model
2.2 Unpacking
DB 5-20 nitrogen generators are delivered to site in two pieces: (a) nitrogen generator skid and (b)
nitrogen buffer tank. The nitrogen generator is shipped in a fully wooden crate. The crate door is
designed to be used as a ramp to remove the generator from the crate. The generator arrives with fil-
tration, CMS vessels, controls, instrumentation, silencer and interconnecting piping fully assembled
inside a cabinet. Casters are installed underneath the cabinet for ease of transportation. The nitrogen
buffer tank (included as standard) is shipped fastened to a pallet with hoses and a pressure relief
valve. The installer is responsible for connecting the generator to the buffer tank.
2.3 Recommended System Layout
Ensure to position the unit so that the clean air discharge is directed into an open area free of
obstructions and with consideration for personnel safety.
Parker recommends installing a 'dry' air receiver downstream of the compressed air
treatment equipment to protect them from surges in air demand.
If using an oil lubricated compressor, Parker recommends that an oil vapor reduction filter
be installed downstream of the dryer and upstream of the generator.
