Expert Commercial Plumbing for Nitrogen Generation Systems: Denommee Delivers for New England Aerospace Contractor

Precision Commercial Plumbing for Specialized Systems

Industrial and aerospace facilities rely on highly specialized systems to maintain safety, performance, and compliance — and Denommee Plumbing, HVAC & Electric has the licensed tradespeople and project management depth to deliver complex solutions on time and to spec. One recent project, completed for a New England-based aerospace contractor, involved the installation and piping of a large-scale nitrogen generation system. This job showcases the expertise and value Denommee brings to commercial plumbing customers seeking MEP excellence.

Project Overview: Nitrogen Generation System Installation for Aerospace Use

For this project, Denommee was contracted to install and pipe a nitrogen generation system inside a dedicated mechanical enclosure at an aerospace manufacturing facility. These systems are critical in aerospace and defense manufacturing due to the need for high-purity nitrogen in applications like inerting, purging, and pressurization.

The installed equipment included an Atlas Copco NGP+ 300 nitrogen generator, a premium pressure swing adsorption (PSA) system that produces high-purity nitrogen directly on-site from compressed air. This type of generator is ideal for facilities aiming to eliminate the logistical and cost burdens of bottled or bulk nitrogen delivery.

How Nitrogen Generation Systems Work

Nitrogen generators function by separating nitrogen molecules from the oxygen and other gases in ambient air using a filtration or membrane system. PSA nitrogen generators like the Atlas Copco NGP+ use carbon molecular sieves to adsorb oxygen at high pressure. The system alternates between two towers to allow for a continuous stream of nitrogen while regenerating the media in the alternate tower.

Typical uses of nitrogen generators in aerospace and industrial environments include:

  • Inerting fuel tanks or components

  • Purging sensitive instrumentation

  • Providing a protective atmosphere for manufacturing

  • Preventing oxidation or combustion during welding

  • Laser cutting operations

  • Electronics manufacturing

These applications require reliable, pure nitrogen delivered at consistent pressures and flow rates, which is why robust piping and installation are critical.

Project Scope and System Components

This nitrogen generation installation included:

  • Atlas Copco NGP+ 300 PSA Generator: The core of the system, capable of delivering high-purity nitrogen efficiently.

  • Receiver tanks and dryers: These components help ensure pressure stabilization and moisture control.

  • High-pressure copper and black iron piping: Installed to transport compressed air and nitrogen across the system. Denommee’s plumbers fabricated and supported multiple tight-radius offsets, vertical drops, and wall-mounted runs with secure hangers and insulation-ready clearances.

  • High-performance unions and isolation valves: These allow for system serviceability and future expansion without shutting down the entire setup.

  • Instrumentation and gauges: Installed on storage tanks and near key service valves to monitor pressure and ensure safe operation.

In addition to precision pipefitting, the Denommee team worked alongside engineers to review shop drawings and deliver precise field verification and layout — key steps to avoiding costly rework and ensuring MEP integration with other building systems.

Craftsmanship and Coordination on Display

Denommee’s licensed plumbers and pipefitters delivered clean, code-compliant runs of both black iron and copper piping. Every joint was carefully aligned and brazed or mechanically joined to ensure leak-free performance under pressure. High-traffic areas featured secure wall brackets and pipe supports that maintained clearances while offering robust structural integrity.

The installation followed best practices for industrial gas systems, including:

  • Proper pressure rating selection for fittings and valves

  • Avoidance of sharp bends and flow restrictions

  • Compliance with NFPA, OSHA, and local building codes

  • System testing and commissioning
