System Overview
Key Terms
Potter IntelliGen
™
Nitrogen Generators are specifically designed to provide clean, dry, high purity nitrogen for use in fire
protection sprinkler systems. The generator is a fully assembled package ready to be connected to a new or existing fire sprinkler
system using a factory pre-engineered air compressor. These easy-to-use systems include all air filtration equipment and controls
required to keep the generator operating at peak efficiency.
The Potter IntelliGen
™
Nitrogen Series operates using membrane technology. The smaller oxygen and water vapor molecules
can pass through (permeate) the membrane quickly. The larger nitrogen molecules are less likely to diffuse through the separator
tubes; therefore, they continue downstream to the separator outlet. The permeated molecules are discharged to the atmosphere
through a vent in the separator housing.
Bypass Mode
– Most nitrogen generators cannot produce enough nitrogen to completely fill the sprinkler system in 30 minutes
required by NFPA 13. Therefore, they contain valves that allow the nitrogen membrane to be bypassed so the system can be filled
with compressed air. The valve setting that bypasses the nitrogen membrane is called Bypass Mode.
Nitrogen Generating Mode
– The valve setting that allows the air to flow through the nitrogen membrane and create nitrogen is
called Nitrogen Generating Mode.
Purging
– Purging is defined as the removal of oxygen from the sprinkler system via a purge valve. The purge valve allows some
gas to escape from the system which requires the nitrogen generator to supply nitrogen to maintain system pressure. This process
therefore increases the nitrogen concentration within the system piping over time.
IntelliGen
™
Controller
The IntelliGen
™
Nitrogen Generator Series is the only line of intelligent nitrogen generators for fire sprinkler systems. At the heart
of the IntelliGen
™
units, is the IntelliGen
™
Controller. The IntelliGen
™
Controller monitors every aspect of the nitrogen generator
to ensure the unit is performing optimally. The IntelliGen
™
Controller monitors pressure, runtime, power, connectivity and
operational mode. Using this information and proprietary algorithms, the IntelliGen
™
Controller can determine if the unit needs
to be in Bypass Mode or Nitrogen Generating Mode. No need to manually change ball valve configurations or worry if the unit
is producing nitrogen. Also, by monitoring the generator activity the controller can indicate the development of sprinkler system
leaks, user interaction, and even if maintenance to the generator is required. Combined with the IntelliPurge
®
Nitrogen Purge
Valve, the IntelliGen
™
Nitrogen Generator is the only system that can truly monitor and protect a sprinkler system.
