It included two conference tracks, five workshops and five EXPO classroom pavilions. The event was so big, we’re splitting our show report into three reports to capture all the activity. 

The Importance of Compressed Air Quality in Nitrogen Generation Systems for Food Packaging

Modified Atmosphere Packaging alters the gas environment inside food and beverage packaging to maintain product freshness and slow degradation and fouling processes. The exact gas mixture used needs to be tailored to the product and can vary significantly. For many products, nitrogen gas is part of the packaging mixture due to its inert nature. 

Texas Recycling Plant Saves Water with Air-Cooled Air Compressors

There are multiple compressed air applications in a waste management facility. This new recycling center uses laser-guided optical sorters to divide waste, with no human involvement on the sorting line. Laser optics determine what type of material each scrap is, then compressed air jets maneuver each piece to its collection area. Compressed air also powers handheld blow guns used for cleaning, as well as the bundling and packaging system. 

Selecting the Appropriate Nitrogen Gas Purity Level for Your Application

Producing nitrogen locally is an excellent way to reduce nitrogen costs and ensure a continuous supply of nitrogen gas at the appropriate purity. The ideal nitrogen generation solution varies by application, based on the specific levels of nitrogen purity, flow, pressure and dryness that are required. Environmental factors such as air quality, humidity and temperature also affect the performance of the system.

The Industrial Sustainability 2025 Best Practices EXPO & Conference Show Report

Compressed Air Best Practices® Magazine launched its first event in Europe, the Industrial Sustainability Best Practices EXPO & Conference, in June 2025 in Barcelona, Spain. Designed to educate and connect factories and specifying engineers on the optimization of industrial compressed air, vacuum and cooling water systems, the event featured 12 hours of conference sessions, exhibits and the first Compressed Air Challenge training to take place in Europe. 

Cardinal Glass Increases Throughput with Dry Compressed Air

With over 49 locations and 10,000 employees, the company’s Casa Grande, AZ, plant specializes in tempering, taking annealed or raw glass, cutting it to size, running it through a 1,250°F (677°C) oven and then using a pressurized air system to quench the glass and turn it into safety glass. Compressed air powers the plant’s belt systems that transfer materials, the seaming system that rounds the corners and the washer system that cleans particulates off glass before it goes into the furnace.

Danmar Industries Custom Engineers for Oil and Gas

The items included three 550 horsepower (hp), oil-flooded, water-cooled, single-stage air compressors with inlet valve modulation capable of providing 1,540 scfm at 165 psi (11.4 bar), two heatless desiccant, 3,138 cfm, 165 psi (11.4 bar) compressed air dryers, and two nitrogen generators for the main station, as well as two smaller air compressors and heatless desiccant compressed air dryers for each of three smaller facilities. Air compressor packages typically meet API 619, but the customer did not request that in this case. The motors, however, need to meet API 547. Air compressor system piping needed to be carbon steel built to ASME B31.3. 

How Breweries Save By Switching to Nitrogen Gas

The brewing industry has long used carbon dioxide (CO2) in various brewing processes. Carbon dioxide has been the workhorse gas for the industry. It’s not only used to carbonate beer and give it fizz, but also to purge oxygen from tanks and lines to prevent spoilage and preserve freshness and flavor throughout the entire brewing process. 

IPS Advises Midwest Industry on Compressed Air Efficiency

IPS supplies compressed air to a lot of machinery running outdoors, such as dust collectors and feed mills on grain elevators, as well as to other equipment in environments lower than 32°F (0°C). Temperatures that low require desiccant dryers. Hoffman helps his customers sort out their options and determine which type of desiccant dryer – heatless, heated purge, heated blower purge – is ideal for their needs.

BEKO Technologies Creates a Culture of Invention and Innovation

“The difference between the floaters and the electronic was that the electronic is much smarter. So, it doesn't only know that it has to open, it also knows when it's not opening, or when it's failing,” explains Tilo Fruth, President of BEKO Technologies. “When mechanical float drains get stuck in the open position – due normally to solid particles in the condensate – they become a significant compressed air leak source.”

Selecting a Reliable and Efficient Nitrogen Generation System

PSA nitrogen generators are fed compressed air which goes to two vessels alternately. One vessel fed by pre-treated air produces nitrogen, and the other undergoes regeneration by depressurization, purging the adsorbed gases, and then repressurization. This cyclic process ensures a continuous supply of nitrogen. The adsorbent materials selectively capture gases like oxygen, carbon dioxide and other trace gases within the compressed air stream while allowing nitrogen to pass through. 

The 2024 AICD Show Report

The Association of Independent Compressor Distributors (AICD) held its annual event at the Grand Sierra Resort in Reno, Nevada, in April 2024. Participating distributor members and guests enjoyed a few days of networking events, the AICD trade show, speakers, the AICD Golf Tournament and more. 

Defining the Purity of Facility Generated Nitrogen Gas

While oxygen is unquestionably the most important gas in our atmosphere, as it is essential for most animals and human life, nitrogen is the most widely used atmospheric gas.  Nitrogen is the go-to gas for countless industrial, medical, and scientific applications. This is because nitrogen is in vast supply, inert, and possesses the desirable characteristics of being colorless, odorless, and tasteless. The purity of nitrogen significantly affects the outcome of the application for which it is used and how the industry measures the purity of nitrogen gas is the focus of this article.
