Industrial Utility Efficiency    

ISO and CAGI

This article will focus on ISO8573-7 normative test methods and analysis for viable microbiological contaminants and how it can be fundamentally utilized in compressed air microbial monitoring plans. The quality of the compressed air must be monitored periodically to fulfill national and international standards. ISO 8573 is an available standard addressing compressed air quality. It consists of nine parts that address purity classes, specifications, and procedures. ISO 8573-7:2003, can be utilized across all industries’ compressed air microbial monitoring plans. It contains both informative and normative procedures but lacks any tested compressed air microbial specifications regarding colony enumeration limits for microbial plate counts.
Organizations across the world are gaining control of their energy spending by measuring and managing their utilities. In doing so, they may be using standards such as ISO 50001:2011 (energy management systems — requirements with guidance for use) to help set up an energy management system (EnMS) that will improve their energy performance. This improved performance might lower energy bills, making products more affordable in the marketplace and improving an organization’s carbon footprint.
The rise in energy prices is an unwelcome reality in today’s manufacturing and business environment. And while the rate of price increases for natural gas, heating oil and electricity may vary from year to year, the upward trajectory is clear. Energy cost reduction strategies are vital to staying competitive. Compressed Air Best Practices® Magazine recently discussed heat recovery, from industrial compressed air systems, with the Compressed Air and Gas Institute’s (CAGI) Technical Director, Rick Stasyshan and with CAGI member – Werner Rauer of Kaeser Compressor. Their inputs should provide you with some insight in energy-saving technology.
In the absence of official third party specifications on energy efficiency, it is difficult to evaluate and compare blower technologies fairly and effectively. The lack of readily available evaluation tools leads to misinformation and unfair comparisons between technologies. Further, the performance verification process is difficult to prove.
Compressed Air Best Practices® Magazine recently discussed variable speed drive (VSD) air compressors with the Compressed Air and Gas Institute’s Technical Director, Rick Stasyshan and with CAGI member – Bob Baker of Atlas Copco. Their inputs should provide you with some insight to this energy-saving technology.
Plant engineers do not purchase air compressors or compressed air dryers on a regular basis. There may be decades between purchases, and with today’s more reliable and durable compressed air equipment, the interval between purchasing decisions grows ever longer. This lack of purchasing frequency, coupled with the significant investment in productivity that compressors and dryers represent, means it is important to make the right decision.
Compressed air is viewed as industry’s fourth utility. Compressed air is frequently the only means of effectively, consistently, efficiently and safely powering certain machinery and processes. It enables users to perform critical work to manufacture, build and process the products we use every day. The world cannot function without compressed air. CABP recently caught up with Rick Stasyshan, the Compressed Air and Gas Institute’s recently appointed Technical Consultant, to shed some light on CAGI’s activities and industry involvement.
The next time you sit down for dinner, take a good look at your food. There’s a very good chance compressed air played an essential role in preparing your meal for consumption.
If you have ever looked at the small print of a compressor brochure or a CAGI Data Sheet or a compressor technical information page, you have probably seen some reference to one of the above standards.  At one time or another, US compressor manufacturers have used these standards to test and report compressor performance.  These are referred to as “Acceptance Test” codes.
Most readers of this magazine are familiar with the ISO 9000 and 14000 families of standards.  The 9000 family pertains to quality management systems and the 14000 family deals with environmental management.
Industry standards serve a very important purpose for the end users of compressed air equipment.  If the standards are well written, they can help to promote the equipment that they govern, as long as the equipment manufacturers properly apply and promote the standards.
