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.
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.

Installation

The Potter NGP-2200D-M5 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.
