2nd GENERATION NITROGEN GENERATOR SYSTEM MANUAL GENERAL DESCRIPTION The N2 Nitrogen Generator is designed for use on tap changers, breakers, main tanks or any other electrical device requiring a gas-blanketed enclosure. The unit produces nitrogen by separating oxygen from compressed air by means of hollow fiberglass separation membranes. The compressed air is supplied by an on-board compressor and the generated nitrogen (N2) is fed to internal storage vessels. The output concentration of the air separator (nitrogen purity) is factory pre-set. The final regulator system maintains the...

2nd GENERATION NITROGEN GENERATOR SYSTEM MANUAL NITROGEN MEMBRANE PRINCIPLE OF OPERATION Refer to Figure 2 below. Compressed air flows into the hollow fiber membrane. Various air components, such as oxygen, nitrogen, carbon dioxide and water vapor pass through the membrane wall, but the rate at which this occurs differs for the various gases. Oxygen and water vapor have a high diffusion rate and diffuse rapidly through the membrane wall. Nitrogen has a low diffusion rate and penetrates the membrane wall slowly, mainly at the end of the hollow fibers. The purity of the nitrogen at the end of...

2nd GENERATION NITROGEN GENERATOR SYSTEM MANUAL SAFETY INFORMATION Proper use of this equipment is important for your personal safety and for trouble-free functioning of the unit. Incorrect control or attempts to perform adjustments could cause damage or lead to incorrect gas supply. Be sure to read and understand all instructions before attempting to operate the unit. The unit is designed to produce nitrogen. The nitrogen is supplied by an internal generator that produces nitrogen from ambient air through a process of separating oxygen from normal air. You must not use the unit for any...

2nd GENERATION NITROGEN GENERATOR SYSTEM MANUAL INSTALLATION – SINGLE TRANSFORMER CAUTION: The unit must be mounted in an upright position. Do not mount unit on its side or back. The unit MUST be vertical for 12 hours before turning the unit on. WARNING: A crane, or similar lifting device, is required to lift and secure unit to wall mounting surface. CAUTION: Do not block the ventilation inlets and outlets as this could cause overheating and damage to the unit. WARNING: Support structure and mounting hardware must be capable of supporting the generator weight of 380 lbs. minimum. Cabinet is...
