GNA Nitrogen Generator

Overview

Advanced PSA technology

GNA nitrogen generators from SCHMIDLIN Labor + Service GmbH & Co. KG provide continuous on-site nitrogen production.

Technology: The generators are based on proven Pressure Swing Adsorption (PSA) technology.
Operating principle: The system uses two columns filled with an inert carbon molecular sieve (CMS) to effectively separate nitrogen from the other gases in air.
Low maintenance: As the entire system contains almost no moving parts, maintenance and repair requirements are minimal.

System layout: compressed air supply with GNA nitrogen generator — System layout of a GNA nitrogen supply.

Control & Safety

Smart control, certified, monitored.

Intelligent control

The control cabinet houses all electrical components, a touchscreen and a PLC that controls all process valves, the condensate drain and the purity sensor.

Certified safety

CE-marked products meet the safety requirements of the EU Pressure Equipment Directive 2014/68/EU and the Low Voltage Directive 2014/35/EU.

Integrated alarm

A low-pressure alarm provides additional operational safety.

Installation

Installation and operating conditions

To ensure lasting and stable performance, the following operating conditions must be met:

Ventilation

The room must be well ventilated to maintain the operating temperature and ensure a proper air supply. Exhaust air must be vented to the outside.

Air supply

The feed air must come from a compressor with a refrigeration dryer and filters (pre-filter and micro-filter) to ensure that it is free of moisture and oil.
