Description
The Potter Nitrogen Generator, NGP-2200D-M5, 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-M5 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.
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.
Technical Specifications
The NGP-2200D-M5 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.
