Nitrogen Generators use a two tank system design to deliver high purity nitrogen to the fire protection
system. The pressure switch on the air tank controls the air compressor by turning it on and off at the desired pressure set points.
A pressure transducer on the nitrogen tank controls the pneumatic valves on the inside of the cabinet. Whenever the nitrogen tank
requires nitrogen, the pneumatic valves open allowing air to flow from the air tank. When the nitrogen tank reaches the desired set
point the pneumatic valves close.
•
Periodic running of the air compressor is expected (typically less than 24 times a day).
