Section 1 Safety & Warnings

This manual contains safety information that is important to know and understand. This information is provided for the

safety of installers, operators, and users of the Nitrogen Generator. To help recognize this information, observe the

following symbols.

Danger indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury.

Warning indicates a potentially hazardous situation which, if not avoided, COULD result in death or serious injury.

Caution indicates a potentially hazardous situation which, if not avoided, MAY result in minor or moderate injury.

Notice indicates important information, that if not followed may cause damage to equipment or property.

1.1 Important Notice to Users

The Installation and Owner’s Manual supplied with each unit must be read thoroughly and completely understood before

installation and operation of the Nitrogen Generator. All appropriate safety standards for handling of gases as determined by

local or national laws and regulations should be followed at all times.

1.2 Unpacking

After unpacking unit, carefully inspect all parts and equipment for any damage that may have occurred during transit.

Make sure to tighten fittings, bolts, etc. before putting unit into service.

1.3 General Safety Information

Important: Read all of the safety information in this manual before operating this equipment. Use of the equipment in a

manner not specified within this manual may impair the protection provided by the generator and could result in an

unplanned release of pressure, which may cause serious injury or damage. Only competent personnel, who have been

trained, qualified, and approved by General Air Products should perform commissioning, servicing, and repair procedures.

When handling, installing, or operating this equipment, personnel must employ safe engineering practices and observe all

related local regulations, health, and safety procedures, and legal requirements for safety.

Ensure that the equipment is depressurized and electrically isolated, before carrying out any of the scheduled maintenance

instructions specified in this manual.

WARNING

CAUTION

NOTICE

Do not operate if damage occurred during shipping, handling,

or use. Contact General Air Products immediately.

The warnings in this manual cover the most known potential hazards, but by definition cannot be all-inclusive. If the user

employs an operating procedure, item of equipment, or a method of working that is not specifically recommended by General

Air Products, the user must ensure that the equipment will not be damaged or become hazardous to persons or property.

Nitrogen is not a poisonous gas. However, in a concentrated form, there is a risk of asphyxiation. The generator produces

a flow of nitrogen and oxygen enriched air which quickly disperses in the atmosphere. However, do not directly inhale the

output gas from the generator outlet pipe.

The generator is classified as non-hazardous for transportation purposes and as non-flammable for fire regulations. This

equipment is for indoor use only. Do not operate outdoors.

Specific procedures must be developed for maintenance of the equipment in which the nitrogen separator is located.

Appropriate labels must be continuously displayed in all areas where personnel might be exposed to a nitrogen

atmosphere under any condition.

WARNING

NOTICE

Operation of the nitrogen separator above the rated design

pressure may be hazardous. Do not connect it to

compressed air sources that can exceed its maximum

rated pressure without installing appropriate pressure

controls and safety relief devices in the compressed air

supply line.

Do not attempt to disassemble the nitrogen generator.

Equipment damage may occur and cause the system to

function incorrectly.

Section 2 System Overview

The NGPSA Nitrogen Generator operates using Pressure Swing Adsorption (PSA) gas separation technology, which utilizes

2 towers of Carbon Molecular Sieve (CMS) to separate nitrogen from the other gases contained in the air. Smaller oxygen

and water vapor molecules latch onto the molecular sieve bed and the larger nitrogen molecules continue downstream to

the separator outlet. While tower 1 is generating an enriched high-pressure stream of nitrogen, tower 2 is purging away all the

waste oxygen and water vapor molecules to the atmosphere. This process occurs for a set duration and eventually the towers

will switch their role; tower 2 generates an enriched nitrogen stream and tower 1 purges away all the waste air to atmosphere.

The Nitrogen Generator is specifically designed to provide clean, dry, high purity nitrogen for use in various process systems.

The generator is a fully assembled package using factory pre-engineered air compressors and controls. These turn-key

systems include all air filtration equipment required to keep the generator operating at peak efficiency.
