Compressed Air Best Practices — Industrial Utility Efficiency

Intercoolers play a critical role in removing heat between compression stages, directly affecting centrifugal air compressor efficiency and reliability. This article explains the fundamentals of intercooler operation, compares common heat exchanger designs and cooling methods, and explores the design tradeoffs engineers should consider when selecting intercoolers for compressed air applications.

Don Eaton, CEO of Sauer Compressors USA, discusses the company’s growth in high-pressure air compressors and industrial air and gas compression. He explores compressor technology, reliability, uptime, strategic investments and distributor training designed to improve customer support and long-term system performance.

This article reviews key Mine Safety and Health Administration (MSHA) requirements affecting compressors, air receivers, pressure systems, piping, hoses and compressed air use. It also examines common field hazards, inspection and maintenance considerations, equipment safety requirements and worker training provisions. Practical examples illustrate how mine operators and compressed air professionals can identify potential hazards and improve safety while working within the applicable MSHA framework.

This article examines the ISA-7.0.01-1996 instrument air standard and its requirements for pressure dew point, particle size, oil content and contaminants. It explains how to select and size refrigerated and desiccant compressed air dryers, filtration systems and air compressors based on operating conditions and application requirements. The article also addresses dew point optimization, compressed air demand, system redundancy, maintenance and leak management, with practical examples from food packaging, oil refining and remote industrial applications.

This article focuses on a project to replace vacuum cups with spring-return magnetic pickups for handling ferrous metal parts at an automobile assembly plant in Missouri. The application is most familiar in automotive stamping and body shop operations, but the lesson applies to any plant using vacuum cups to grab steel blanks, panels, brackets or formed parts. The original equipment in this case study used vacuum cups served by venturi devices.
