Compressed Air Audits: A Holistic Approach -Addressing the Air System as a Whole
First, consider the Independent Auditor. Plant management should consider using an independent auditor without ties to equipment sales who has experience with a variety of manufacturing facilities and can provide strong references documenting proven energy savings. The quality and comprehensiveness of manufacturing facilities, and therefore audits, vary widely and it is important to consider experience. Compressed Air Technologies has audited nearly 200 manufacturing facilities since our inception in 1996. Compressed Air Technologies is the preferred air energy services provider for Georgia Pacific Corporation, INVISTA Chemicals and a primary energy partner with KRAFT Foods, among others. Compressed Air Technologies has no OEM affiliation of any kind and will provide recommendations that are system-neutral and commercially impartial. Compressed Air Technologies (CAT) is an international energy reduction and system optimization services corporation. CAT is a totally independent business structure with no ties or affiliations with any air compressor manufacturers -we are free of OEM restrictions. Our strict adherence to an independent approach related to compressed air and gas system assessments allows for unbiased commentary and recommendations, regardless of the brand or equipment type currently utilized in your plant. The majority of our competitors have either 1) equipment to sell and/or,2) existing equipment on the site to protect. In both situations, the interests of the client is not the paramount issue. Independent auditors should have no obvious or hidden agenda. CAT compressed air audit services are in essence, holistic. The analysis of your facility compressed air and gases systems is all-inclusive and consists of an engineered assessment beginning at the air compressor equipment area inside your facility and finishing at point-of-use consumption points. CAT engineers utilize a variety of instruments to collect data from all critical, relevant areas of the compressed air and gas systems. From air compressor blow off loss to the cost of the always present distribution/ piping system leaks, each individual loss or inefficiency is measured, analyzed, quantified and catalogued. CAT engineers then compile all of the collected data to create a total current profile report of your facility operations including an assigned cost to each discovered inefficiency. A typical audit results in identification of 25 to 60 percent or more in total system operational waste, which includes energy costs, maintenance costs, and all matters related to operating your compressed gas systems. It is not unusual to discover half of what you pay for compressed air operations is wasted due to inefficient utilization and operation of this important utility.
