Description
The Potter Nitrogen Generator, NGP-500D, 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.
Potter Nitrogen Generators are fully assembled packages ready to be connected
to a new or existing fire sprinkler system. These turn-key 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-500D 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-500D 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 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 #5401548.
