N2GEN-FLEX Series Site and Utility Requirements – South-Tek Systems

This article applies to South-Tek Systems industrial N2GEN-FLEX series PSA nitrogen generators.

Proper site preparation is required to ensure safe operation, maintain system performance, and allow access for service. Before startup, confirm that the installation area, electrical supply, compressed air supply, and utility connections meet the requirements below.

Installation environment

Install the system indoors in a clean, dry, well-ventilated area.
Ambient operating temperature must remain between 40°F and 90°F (4.44°C to 32.2°C).
Performance derating applies at temperatures above 90°F.
The skid must be installed no more than 5° off level.
The area should be reasonably clear of dust and debris.
Maintain at least 3 feet of clearance on all sides of the skid for service and maintenance access.

Ventilation and safety

Nitrogen is odorless and can displace oxygen in enclosed spaces. The generator must be installed in a room with adequate ventilation. This equipment is intended for installation and use by trained personnel only.

Electrical requirements

Power supply: 100-240 VAC, 50/60 Hz, single phase
Maximum current draw: 2.1A
Electrical connections should be reviewed and completed by an electrician authorized to work in the installation jurisdiction.

Compressed air requirements

Compressed air supplied to the generator must comply with ISO 8573-1, Class 1.4.1.
Published performance data for the N2GEN-FLEX series is based on 79°F ambient conditions and 100 PSIG air inlet pressure.
Air quality, pressure stability, and proper upstream treatment are critical to generator performance and long-term component life.

Mounting and placement

The generator is skid mounted and should be placed on a suitable flat surface capable of supporting the system.
Bolt holes are included on the bottom of the skid if anchoring is desired.
Floor mounting is optional unless required by site-specific conditions or local code.

Utility connections

Confirm connection locations and orientations before final placement. Refer to the model detail drawing included with the system documentation for exact layout and connection locations.

Compressed air inlet: 0.75" NPT
Nitrogen outlet: 0.75" NPT
Condensate drain: 0.25" OD connection

On larger configurations with an integrated buffer tank arrangement, additional buffer tank connections may be present based on the model configuration.

Before startup

Verify utility connections are complete and leak free.
Verify the electrical supply matches the system requirements.
Confirm the installation area meets clearance and ventilation requirements.
Confirm incoming compressed air meets the required quality specification.
Schedule virtual training or on-site commissioning with South-Tek Systems prior to operation.

Important note

N2GEN-FLEX systems are factory tuned to perform to the required operating conditions. Do not adjust valves, regulators, or PLC settings without consulting South-Tek Systems.
