There are indeed rewards for machine builders who sweat the small stuff. The latest iterations of many tiny but essential components like sensors, cameras and switches can pack a great deal of innovation for their diminutive size. 

A large food manufacturing operation in the U.S. Midwest spends $529,000 annually on energy to operate the compressed air system. The plant current has two supply-side systems that operate and feed two different distribution networks at two different pressures. One compressed air system is at 115 psig (medium pressure system) and the low-pressure system is at 30 psig. The compressed air equipment for both systems is located in four areas throughout the facility. 
 

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. 

CAGI sponsors and oversees a performance verification program for some types of equipment. In this program, which is expanding to include additional types of products, a third-party verifies performance data that is stated by manufacturers. Participants in these programs are able to use a standardized CAGI datasheet to state performance. The datasheets and verification process provide customers with assurance that they are getting what they pay for in terms of performance. The program also provides credibility to participating manufacturers, who stand by their data and are willing to put their reputations on the line through third party testing and verification.
