Industrial Utility Efficiency

System Assessments

Given that compressed air leak management programs are meant to save energy, reduce CO2 emissions, and generate ROI, DENSO’s Maryville, Tennessee, manufacturing facility can definitively say it has scored a trifecta when it comes to results – and reaped benefits beyond hard numbers alone.

Plastic Injection Molder Saves Energy

The facility is a plastics injection blowmolder and is a division of a large corporation. The following information was produced from a compressed air system assessment done over seven days.

Energy-Saving Compressed Air Resin Dryers

Resin drying is a critical step in the manufacturing process of injection molding, extrusion molding and stretch blow molding.  Compressed air resin dryers are one of the most commonly used dryers in the plastics molding industry. Recent advancements in compressed air membrane-type resin dryers, have reduced the associated energy costs significantly.

An Automotive System Assessment

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.

Chrysler Finds Vacuum Savings of $400,000 per Plant

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.

A Food Processing System Assessment

This facility processes bulk food ingredients into finished packaged food products. The factory belongs to a division of a large corporation and was spending \$732,342 annually on energy to operate their compressed air system. This system assessment detailed twelve (12) project areas where yearly energy savings totaling \$214,907 could be found with a minimal investment of \$68,350. Due to space constraints, this article will detail only the higher impact project areas. The over-all strategy for improving this air system centers on improving specific power performance of the #3 centrifugal air compressor and reducing over-all demand with compressed air savings projects.

Seven Sustainability Projects: Air Compressors

Reducing energy costs and pollution emissions involves many areas within an industrial facility.  My studies have found seven (7) key (or common) areas where low cost practical projects can be implemented.  Combined, these projects provide savings exceeding 10% of the annual energy spend with an average payback of less than one year.

Assessment Improves Electroplater Production

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.

Boiler Soot-Blowing in Power Plants

Utilities have been cleaning their boilers for many years using either steam or high-pressure air.  In the past, when air was used, due to the size of the boilers and the reasonable quality of fuel used, a relatively small amount of cleaning was required.
