Description
The Potter Nitrogen Generator, NGP-2200D-M2, is specifically designed to
provide on-site, high purity nitrogen for use in fire protection sprinkler
systems. When used as a supervisory gas in fire sprinkler systems, nitrogen
slows corrosion, improves the life of your system, and lowers maintenance
costs. The NGP-2200D-M2 includes a tank mounted air compressor, nitrogen
cabinet, and a nitrogen storage tank. These systems include all air filtration
equipment, an air compressor, nitrogen membrane, as well as tanks required to
keep the generator operating at peak efficiency. Potter Nitrogen Generator
Systems provide a low cost, reliable, and efficient method of producing a
minimum of 98% nitrogen at the point of usage.
The NGP-2200D-M2 utilizes nitrogen membrane technology for gas separation.
Nitrogen membranes are highly effective and a cost conscious way of producing
on-site nitrogen. Acting as a filter, the smaller oxygen and water vapor
molecules can pass through the membrane quickly. The larger nitrogen molecules
are less likely to diffuse through the separator tubes; therefore, they
continue downstream to the separator outlet, through the air maintenance
device and into the fire protection system. As the system fills with nitrogen,
the remaining oxygen molecules in the fire protection system are exhausted by
using the Potter IntelliPurge® Nitrogen Purge Valve. The Potter IntelliPurge®
Nitrogen Purge Valve will periodically monitor the fire protection system to
ensure high purity nitrogen is consistent throughout the sprinkler system.
Installation
The Potter NGP-2200D-M2 should be installed in a dry, clean, and well-
ventilated room with ambient temperatures above 50°F at all times. Allow
access to the front of the nitrogen cabinet for service and place the unit in
a location that is conveniently located near fire sprinkler system connections
and a drain.
The Potter Nitrogen Generator should always be installed in an adequately
ventilated room. Nitrogen is nontoxic and largely inert. Rapid release of
nitrogen gas into an enclosed space displaces the oxygen and can cause an
asphyxiation hazard. Inhalation of nitrogen in excessive concentrations can
result in unconsciousness without any warning symptoms.
For detailed installation and operation instructions please refer to the
Potter Nitrogen Generator Manual #5401550.
