ASHRAE 90.1 Brings New Requirements to Compressed Air System Design

By Troy Dreier, Compressed Air Best Practices® Magazine

Word is beginning to filter out about the 2022 changes to the ASHRAE 90.1 energy efficiency standard, and the changes it promises to bring to how compressed air systems are specified, commissioned and maintained. More specifically, the industry is learning about section 10.4.6 of 90.1, which is the first time the standard has included a section on compressed air.

Exploring the Total Cost of Ownership of Oil-Injected vs. Oil-Free Compressed Air Systems

By Brian Mann, ME, PE, Air Systems Manager, Sullair

The purity of the compressed air that contacts finished goods and their packaging is scrutinized more than ever before. As a result, oil-free air compressors comprise a larger segment of the compressed air market than ever before. In fact, Grand View Research, Inc. projects a CAGR of 4.8% for the oil-free market as compared to a CAGR of 3.8% for the market as a whole (2019-2025).

Preparing Reciprocating Air Compressors for Winter

By the Compressed Air & Gas Institute

Freezing temperatures can have negative effects on your reciprocating air compressor, dryer, and many accessories. One of the best practices to adopt is keeping a detailed maintenance log. At the end of each season, take note of the condition your equipment is in, and address it promptly using the manufacturer’s instructions to keep it operating smoothly and efficiently.

Promote Sustainability with an Optimal Air Compressor Lubricant

By Jasween Jagjit-Webb, Market Manager-Air Compressor Lubricants, Klüber Lubrication

When facilities look to improving sustainability, they tend to focus first on traditional energy utilities – natural gas, heating oil, electricity and water. As facilities achieve greater sustainability through efficiencies that reduce utility energy waste and minimize the plant’s carbon footprint, they begin to focus on other energy sources, including compressed air, to enhance sustainability efforts.

The Gentex Journey to Reliable Energy Conservation - 3 Levels of Compressed Air Systems

By John Bilsky, Facilities Maintenance, Gentex Corporation

The information contained in this article, will help the operator to assess his/her systems, and identify where these systems fall within a three-level category. There are many ways, and opportunities to make a compressed air system produce reliable and good quality air. The three levels discussed here could also be characterized as a “continuous improvement plan” which can be achieved over the course of time, and with the occasional investment of money.

HAUG Oxygen Compressors for Efficient Gold Extraction

By Paul Frank, Technical Proposal Manager, Sauer Compressors USA

Logistics and supply problems are widespread on the African continent. Lack of infrastructure as well as capacity and efficiency deficiencies can affect supply chains and make them more expensive. Gold mines, which are often located in secluded areas, therefore seek to provide their entire infrastructure themselves. Even the oxygen required for efficient gold extraction by cyanide leaching is therefore not delivered but generated on site.

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.

Milk Plant Deploys the Second Stage of Energy Savings

By John Molnar, P.E., Rogers Machinery Company

Yearly energy reduction quotas drive utilities, plant, and energy managers to continue to reduce energy consumption in all areas. A frequent question asked is, “Where can we find more energy savings once we have a VFD compressor and we have fixed all our leaks?”

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.
