Leland Brewing Adopts Modular Nitrogen Generation

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine 

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.

On-Premises Nitrogen Generation Addresses Carbon Dioxide Supply Concerns for Breweries

By Garrett Rinker, Senior Project Engineer, South-Tek Systems

The initial cost of a nitrogen generation system may be greater than high-pressure cylinders and liquid nitrogen containers, but most companies will reach a return on investment within 12-18 months with proper sizing of the system based on process demands. Breweries typically experience savings associated with gases of 50-75% by switching to on-premises nitrogen generation. If a regular maintenance schedule is followed, PSA nitrogen generation systems can have a life expectancy of 15-20 years.

Moisture: the Assassin in Compressed Air Installations

By Pascal van Putten, CEO, VPInstruments and Frank Moskowitz, Instructor, Compressed Air Challenge

Moisture can freeze in compressed air systems and cause rust and pitting in pipes and components. It can also flush out the lubricant resulting in accelerated tool wear and damage to valves and cylinders. Moist air is also a rewarding breeding ground for bacteria, which especially in the food and pharmaceutical industries can lead to product rejection and costly production downtime. It is therefore strange that many companies limit themselves to measuring only basic quantities such as pressure, flow and (absorbed) power.

Metal Fabricator Measures Nitrogen Use, Receives a Surprise

By Ron Marshall, Marshall Compressed Air Consulting

Nitrogen is used in many facilities for a variety of purposes. The most common source of N2 is through the use of bulk liquid storage. A plant owner was recently surprised to learn that a large portion of his N2 was disappearing, without ever being used by his production process. This article discusses where it went and what we could do about it.

Compressed Air Dryer Key Performance Indicators

By Chris Beals, President, Air System Management

The purpose of this article is to point out the key performance indicators (KPI’s) that can assist in maintaining the performance and troubleshooting of compressed air dryers. The most important KPI to monitor is the pressure dew point (PDP) of the compressed air exiting the dryer(s). The PDP of the compressed air should be monitored at the discharge of each dryer and downstream of where the compressed air from multiple dryers converges.

Sterile Compressed Air Filters Remove Bacteria

By Peter Gray, Air Solutions Canada

When compressed air comes into direct contact with a product, many applications believe their “standard” particulate and coalescing oil-removing filters, installed either side of a compressed air dryer, are sufficient to protect the downstream processes. Strangely enough, the removal of bacteria is often overlooked, despite this level of filtration being readily available, easy to procure, install and maintain.

Nitrogen Characteristics and Benefits of On-Site Generation

By the Compressed Air & Gas Institute

Modified Atmosphere Packaging (MAP) accounts for a significant amount of nitrogen usage in the food and beverage industry. MAP involves injecting nitrogen into beverage or food packaging to purge and displace any oxygen-containing air with nitrogen. Oxidation of lipids in food products causes rancidity. Since oxygen is replaced with dry, inert nitrogen in MAP packaging, no product oxidation will occur. The result is maximized product shelf life.

Designing Efficient PSA Nitrogen Generation Systems for Food & Beverage Production

By Alan Hopkins, Purity Gas Inc.

This article is for you if your company is purchasing nitrogen gas at 99.999% purity and you’re not sure why.  While there are many applications which do require nitrogen gas concentrated to 99.999%, they are significantly outweighed by the applications that don’t. Rather than relying on a delivery of bulk liquid or pressurized cylinders, many nitrogen users are choosing to produce a custom supply of nitrogen within their facility, and they are doing it at a fraction of the cost. Over the past decade we’ve seen a mass industry shift from delivered nitrogen supply, to nitrogen generation.
