Nitrogenator® Nitrogen Generator ORIGINAL | 1998 Service Information

No votes yet


THE AC NITROGENATOR® IS THE FIRST ON-SITE NITROGEN GENERATING GAS SYSTEM DESIGNED AND MANUFACTURED BY A BEVERAGE SERVICE COMPANY! The AC Nitrogenator® was the first model developed by AC Beverage. The Nitrogenator® was placed in the market in 1998. Today there are many in the market still functioning. As technology has evolved so have our generators. We have streamlined the unit through the years to become more efficient. We no longer sell this model, however maintenance and service information is below.

The Elite Nitrogenator® is the most current model:

Maintenance and Service Information

The AC Nitrogenator is a Nitrogen generating system that converts compressed air into Nitrogen utilizing state-of-the-art membrane technology. The PRISM Alpha Membrane is the heart of the system, which consists of a bundle of hollow fiber membranes. The compressed air enters the center core of the fibers and travels the length of the module. As air travels along the fiber, Oxygen, CO2 and water vapor molecules pass through the membrane wall faster than the Nitrogen molecules. This results in a high purity dry Nitrogen stream exiting at a low pressure.

INSTALLATION: The AC Nitrogenator should be located in an area where the ambient temperature is between 38F and 100F (3C and 38C). Installation of the AC Nitrogenator in an area where the temperature falls outside this range may affect the performance and/or the life of the system. The environment surrounding the AC Nitrogenator must be well ventilated also.

MOUNTING - The AC Nitrogenator can sit on a flat surface or be wall-mounted. If wall mounted, a supporting member of a wall, such as a stud must be used to secure the unit. Drill mounting holes into the wall using the mounting template outlined on the packing box. The AC Nitrogenator must be in a vertical position to maintain proper operation of the pre-filter float drains.

DRAIN LINES – The drain port coming from the pre-filter and air compressor condensate drain must be connected to an appropriate disposal container or drain. The liquid in this drainage will consist of water and compressor contaminants.

COMPRESSED AIR– The AC Nitrogenator requires a source of clean dry compressed air for operation. The air should be between 60F and 110F (15C and 43C) and have a dew point lower than the ambient temperature of the installation location. The incoming compressed air pressure should be between 100 psig and 125 psig., unless the AC Nitrogenator has been ordered to operate at a lower pressure range. The AC Nitrogenator requires .5 SCFM of compressed air for operation. The compressed air system that supplies the unit should have adequate capacity or the performance of the system will be compromised.
NOTE: AC Beverage recommends the use of the model #T-617-6Z948, ½ HP Beverage Service air compressor outfitted with an electric auto condense drain, which has a proven performance record.

PRE-FILTRATION – The AC Nitrogenator comes equipped with a .01-micron coalescing filter to remove dust, hydrocarbon vapors and water vapor. Additional pre-filtration may be required in applications where air borne contaminants are evident or high humidity conditions exist.
NOTE: AC Beverage recommends the use of model #831A Carbon pre-filter in extreme conditions.

CONNECTIONS – Pipe the AC Nitrogenator per the illustrated diagram shown on Principal Specification Sheet.

START-UP – Plug the air compressor power cord into an appropriate 120 VAC/60 Hz power receptacle and operate until fully charged to 120 psig. Plug AC Nitrogenator into appropriate 120 VAC/60 Hz power receptacles and note that the red and green lights illuminate. These indicators allow for visual inspection that power is on “Red” and that Nitrogen production “Green” is taking place.

LEAK TEST – Turn storage tank valve located on the Distributor off and both blender gas outlets. Observe N2 pressure gauge as it should rise to 100psig. At this point, the “Green” N2 production light should shut off. Monitor system for a minimum of 15 minutes to ensure that pressure remains at 100 psig and that “Green” light remains off. Upon completion of leak test, turn on valves to storage tank and allow system to pressure up.

OPERATION – The AC Nitrogenator will operate continuously as long as it receives power and compressed air. The air compressor should not cycle continuously during normal operation. However, the compressor may cycle on and off frequently during periods of high dispense gas demand.

NITROGEN BACK-UP TANK– An emergency back-up tank set to 100 psig should be connected to the system to allow for a Nitrogen source in the event of compressor failure or major leak in beer dispense plumbing. If Nitrogen pressure drops blow 40 psig the back-up tank should be turned on to rebuild pressure to at least 90 psig. In the event of a compressor failure, the tank should remain on until compressor is repaired or replaced. The back-up tank is designed to assist the AC Nitrogenator in the event that the demands for Nitrogen exceed the output levels. Turning the back-up tank on to recharge system is an option during extreme volume situations.
