UniFirst is one of North America’s largest workwear and textile service companies. They outfit nearly two million workers in clean uniforms and protective clothing each workday. Founded in an eight-stall garage in 1936, the Company has grown to 240 customer servicing locations throughout the U.S. and Canada servicing 300,000 business customer locations. The subject of this article is an energy-saving Air Demand Analysis (ADA), conducted by Kaeser Compressors, at UniFirst’s centralized 320,000 square foot hub Distribution Center located in Owensboro, Kentucky.
Compressed Air Best Practices interviewed Mr. John Malinowski, Senior Product Manager-AC Motors, Baldor Electric Company.
This factory currently spends $735,757 annually on the electricity required to operate the compressed air system at its plant. The group of projects recommended in the system assessment will reduce these energy costs by an estimated $364,211 (49% of current use). Estimated costs for completing the recommended projects total $435,800. This figure represents a simple payback period of 14.4 months.
Compressed Air Best Practices interviewed Richard Feustel, the Corporate Energy Manager of Briggs & Stratton.
Compressed air leaks - every system has them.  Is a leak identification and control program economically rewarding and/or necessary? Upper management sometimes doesn’t recognize the true cost of not repairing air leaks.  Knowing the high cost of compressed air, why wouldn’t every facility with a compressed air piping system implement a continuous leak identification and repair program?
This article presents a case study of Grimmway Farms; a carrot growing and packing firm located in California’s Central Valley that was able to improve its compressed air system efficiency after implementing system automation and making relatively small equipment and piping changes.
Easy-to-implement master control and monitoring systems provide crucial system information including the key performance indicators required to manage air compressors and their associated energy costs.
We are finding significant changes in industry with regards to which managers are involved with our discussions.
Productivity and profits are very directly linked to the compressed air system, as is waste elimination. High performance central compressed air management systems can respond quickly to even extreme system fluctuations, improving productivity and minimizing energy waste.  This is accomplished with modern software systems analyzing and processing appropriate data and triggering proactive actions - before the dynamics effect the compressed air production system.
In today’s world, where “green” is “gold”, the efficient operation of multiple air compressors has taken on a new sense of urgency. In an era where giant manufacturing campuses with huge compressed air systems are fast disappearing, the emphasis shifts now to improving the efficiency of the higher numbers of installed small and medium size air compressors.
Sustainability at RRD starts with a philosophy. It is then executed through a global policy and objectives. RRD’s philosophy does not see sustainability as making a choice between being cost-effective and improving environmental impacts. On the contrary, sustainability represents integrating these two factors. This philosophy guides our sustainability objectives and strategies.
