Industrial Utility Efficiency

# Vac Generation

You have your equipment, everything is set up and ready to run, but what about your lubricants? Too often, lubricants receive little attention with respect to their use in rotating equipment. Even the most reliable cars in the world will encounter problems on a short commute if the wrong transmission fluid is used during a flush. The same is true with your Positive Displacement (PD) blower or vacuum booster that operates around the clock. In our experience, approximately 80% of all bearing and gear failures are the result of improper lubrication.

## Utilizing Venturi Vacuum Generators Efficiently

Air-driven Venturi vacuum generators have long been a viable option for fast-response, localized, vacuum-powered systems. Through the last decade, they were considered convenient and flexible solutions with quick response time. However, they were not regarded as energy efficient, probably due to their use of compressed air. Extensive product development with this equipment — particularly the crucial system accessories — often makes the selection of the most energy-efficient items difficult for many localized operations.

## Optimizing Vacuum Generators in Case Packers and Palletizers

This was a complete supply and demand-side system assessment. The supply-side audit involved shutting off old air compressors and purchasing newer more efficient air compressors and dryers. The demand-side audit involved finding ways to improve the piping and reduce compressed air consumption.

This food industry factory, located in California, was spending \$386,533 annually on energy to operate their compressed air system. This system assessment detailed eleven (11) project areas where yearly energy savings totaling \$154,372 could be found with a investment of \$289,540. A local utility energy incentive, paying 9 cents/kWh, provided the factory with an incentive award of \$159,778. This reduced the investment to \$129,762 and provided a simple ROI of ten months on the project. ## The Ins and Outs of Vacuum Generators There is an enormous population of vacuum generators being used successfully by industry. Applications range from pick & place to vapor extraction to bulk material handling and the number of installations is growing. Before proceeding with an installation utilizing these devices, there are two general issues to consider: efficiency and appropriateness. ## Reducing Packaging Cycle Times Swiss brush company Ebnat-Kappel uses non contact transfer technology from Bosch Rexroth to automate a problematic section of its packaging production process. ## 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.
