System Assessments

We asked a hand-selected list of original equipment manufacturers, independent compressed air system sales and service companies, manufacturing plants and independent system auditors to share their thoughts, highlighting the changes they’ve seen over the past 20 years, then predicting what the next 20 years will bring.

20 Years of Case Studies: Plants Sharing Best Practices

For 20 years, Compressed Air Best Practices® Magazine has published articles focused on helping manufacturers reduce power demand, lower water consumption, and improve the performance of compressed air, cooling, blower and industrial vacuum systems. In this article, we highlight a sampling of those stories across the following industries: Plastics and Packaging Food and Beverage Automotive and Transportation Cement, Building Materials, and Mining Metals, Pulp, and Paper Pharmaceuticals, Healthcare, and Research Wastewater Treatment 

Sizing Compressed Air Piping to Manage Pressure, Flow and Velocity

Efficient compressed air distribution depends on proper piping design to balance flow, pressure and velocity. This article explains how modular aluminum piping systems improve performance by reducing friction, minimizing pressure drop and maintaining laminar flow. With smooth interiors, full-bore fittings and leak-free connections, these systems help lower energy consumption and extend equipment life. A real-world case study shows how an optimized design reduced material and installation costs while maintaining performance. The result is a more adaptable, efficient and reliable compressed air network for modern industrial facilities.

Morey Cuts Nitrogen Costs by $270,000 with On-Premises Generation

What started as a cost concern quickly exposed deeper risks tied to supply reliability, contract constraints and production downtime. Facing a tight deadline, the electronics manufacturing company executed a rapid transition to an on-site nitrogen system that reshaped how its operation is powered. The results reveal why more manufacturers are rethinking their dependence on delivered industrial gases.

Leland Brewing Adopts Modular Nitrogen Generation

A modular nitrogen generation system integrated with compressed air infrastructure enabled on-site nitrogen production, reducing reliance on delivered CO₂ and improving process efficiency. Adjustable nitrogen purity levels (e.g., 99.99%) optimized flow rate and demand matching while maintaining product quality in brewing applications. The implementation demonstrates how scalable nitrogen generation technology can lower operating costs and support growth in small to mid-sized industrial operations.

Dishaka Strengthens Operational Efficiency with Onsite Nitrogen Generation

A snack manufacturer, strengthened operational efficiency and product freshness by implementing onsite nitrogen generation at its Houston facility. By replacing delivered nitrogen with PSA-based systems from Liberty Systems, the company gained 24/7 supply reliability, reduced operating costs and improved sustainability performance. The investment supports scalable Modified Atmosphere Packaging (MAP), enhances business continuity and positions Dishaka for long-term growth in the competitive food manufacturing industry.

Advanced Compressor Technologies Solves Oversupply Problem

A Southern Indiana office furniture plant was wasting hundreds of dollars per day because its oversized VSD air compressor could not turn down low enough to match reduced demand after a shift to metal fabrication. To avoid drive faults, the plant vented compressed air to create false load. The audit revealed 300 cfm of wasted air—about $400 per day—and led to a redesigned system using a fixed-speed compressor for base load and a VSD unit for trim. The new configuration eliminated artificial demand and cut compressed air energy use in half, setting the stage for further savings through advanced sequencing, storage, and demand control.

Egger Modernizes Its Compressed Air System for the ESG Era

Wood-based materials manufacturing plant transformed its compressed air system from an invisible utility into a data-driven energy asset by deploying a modern, multi-zone monitoring and control platform. The upgrade delivered real-time transparency, ISO 50001- and ESG-ready reporting, and verified annual savings of 1.43 GWh, \$166,500 and 889 tons of CO2.

The Business Case for Air Compressor Rentals and Air-Over-the-Fence

There is no single right approach to putting the necessary volume and pressure of air in the pipe to meet production needs. There is a place for purchasing assets, there is a place for renting assets and there is a place for an AOF contract. Just as the business models around these assets change, so do the needs of an industrial plant. This article aims to explore these options and explore some of the pros and cons associated with different methods. 

ADG Concepts Solves Years of Piping Problems for Frozen Foods Plant

They got to a point where every time they added a new piece of equipment, it did not eliminate their rental, nor did it eliminate the water problems, the leaks and everything else they were experiencing. The system had issues that adding more equipment simply could not fix.

Industrial Blowers Reduce Energy Use in Aluminum Casting Plant

This article explores how a focused engineering intervention driven by data and a clear understanding of process requirements led to a transformative change on a aluminum production plant.  By switching from traditional compressed air systems to low-pressure industrial blowers the plant not only maintained product quality, but also achieved a dramatic reduction in energy use saving nearly \$455,000 annually.
