Lubricant Chemistry and Oil/Water Separators

By David Rosenthal, SA Performance

Air compressors can produce a lot of water. Humidity in ambient air, once compressed, results in much of this water falling out, which we know as condensate. On a warm and humid summer day with inlet air temperatures of 80 oF, a 75-horsepower (hp) air compressor running fully loaded can produce over 25 gallons of condensate in just one eight-hour shift, with another five gallons being produced once the compressed air is sent through a dryer. The compression process allows for the air, water vapor, and lubricating fluids to mix. Once the condensate leaves the system, trace amounts of lubricant travel with it.

How to Avoid Control Gap with VFD Rotary Screw Air Compressors

By Tim Dugan, P.E., Compression Engineering Corporation

Air compressors need to be matched to load effectively and efficiently. If the air compressors’ range of variation can’t be matched to the system variation, instability and/or inefficiency can result. This article discusses the problem when it isn’t matched, which is called “control gap” and what to do to avoid it.

TE Connectivity’s Focus on ROI Drives Sustainability Success and Compressed Air Savings

By Mike Grennier, Compressed Air Best Practices® Magazine

The company is succeeding with sustainability at many operations, including its manufacturing plant in Lickdale, Pennsylvania. In fall 2019, officials from the Department of Energy’s Better Plants program joined company officials there to celebrate the plant’s energy achievements – including an 11% reduction in compressed air energy costs. Its ability to reduce the cost of compressed air to the tune of $223,000 per year is a prime example how many TE Connectivity operations have fully embraced sustainability.

Heat of Compression: A Major Energy Recovery Opportunity Often Ignored

By Hank van Ormer, Air Power USA

Often when you mention heat of compression the first thought generally relates to HOC desiccant dryers, which are also an under-applied opportunity for heat recovery. However, there are many other heat of compression recoverable energy savings opportunities in all compressed air and gas systems. This article reviews many opportunities in energy heat recovery and provides answer to commonly asked question.

Winpak Reduces Demand by 33% and Switches to Oil-Free Air Compressors

By Ron Marshall, Marshall Compressed Air Consulting

By making changes primarily focused on compressed air uses, Winpak, an international plastics products manufacturer based in Winnipeg, Manitoba, Canada, increased compressed air production capacity and reduced annual energy consumption by 33%. These benefits have been accomplished while the company was making the switch to lubricant-free compressed air to support product quality goals. This article discusses some of these changes and addresses measures that could be implemented in any compressed air system.
