End Uses

There are a tremendous variety of unique and creative ways people in the food industry have overcome their need for compressed air blowoffs used for cleaning, drying, cooling, conveying and overall processing. You may have seen some of them yourself. It is not uncommon to view open copper tubes, pipes with a crushed end, plugs or caps with holes drilled into them, modular flex coolant lines or nozzles designed for liquid application but blowing air.
This commercial printing facility is located in the Northeastern part of the U.S.  Like most facilities, the plant has seen many changes over the years.
This article will focus on a compressed air system assessment done at a printing facility in Canada. The energy costs at the time, in Manitoba, were $0.025 per kWh and the installation was of just 65 horsepower of 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.
Over the last several decades, Air Power USA has reviewed many various types of plastic injection molding operations throughout the U.S.
A recent comparative vacuum technology study performed by Dr. Kingman Yee, as part of a Chrysler Summer Intern Professors Program, found that air consumption could be reduced by 98% when equipping a robot’s end-of-arm tooling with COAXÆ technology and a Vacustat™ check valve.
This stamping plant is a 2.5 million-square-foot facility with over two thousand employees.  At the time of the assessment, the plant was processing approximately 1,600 tons of steel per day into automotive vehicle components and parts such as body parts.
Faced with rising energy costs, a large electroplating company sought to improve the efficiency and reliability of its compressed air system. After getting a quote from their vendor on a new 300-hp compressor to replace an existing unit, the company sought a comparison quote due to the significant investment the new compressor represented. Based on a recommendation from one of their customers, they turned to Scales Industrial Technologies.
Boeing Canada has replaced their onsite membrane style Nitrogen generator with a new more modern system with increased capacity and higher efficiency.  As a result, the company is now using minimal amounts of expensive liquid Nitrogen, and has reduced the energy cost per unit of gas produced by 83%.
Relatively few people realize that for a variety of industrial manufacturing applications, from air knife drying to simple blow-off nozzles, the use of high pressure compressed air that bleeds into the atmosphere represents a significant waste of energy.  
This steel processing facility has been operating for over one hundred years.  This facility is part of a large corporation with numerous plants around the world.  This audit focused on the compressed air system on one side of the Works which we will call the “North Plant”.
