### Best Practices Conference Sessions

Here is a sampling of the presentations during the 2 ½ day technical conference.

Sarah Solberg, Director of International Sales at Solberg Manufacturing, presented “Water-Separator Application Engineering Enabling Use of Dry Vacuum Pumps.” The presentation emphasized the need to protect both the vacuum equipment from the process, and the environment from the equipment in industrial applications. Offering an in depth look at vacuum filtration, Sarah encouraged her audience to take the time to pick the right vacuum filter today so that problems can be prevented rather than fixed later.

Walter See, product marketing manager for the Industrial Vacuum Division of Atlas Copco, presented “Plant Reduces Water Use by Switching to Dry Vacuum Pumps.” This presentation examined the case of a brewery in Oregon that changed their vacuum pump system to a dry pump, saving 5,000 gallons of water per day and saving \$35,000 per year in water and sewage expenses. Additionally, this project had unexpected energy and product savings that propelled the project to a 14-month payback period. Walter also presented “Applying VSD Vacuum Technology for Energy Savings.” Jim Timmersman, Senior Auditor with Power Supply Industries, presented “Chilled Water Load Reduction Case Study: Evaluating Requirements for Air Compressors.” Jim took his audience on a journey to understand the incredible energy savings that can be realized through compressed air heat recovery projects. He also reviewed his experiences receiving utility incentives tied to heat recovery projects and the opportunity this presents to manufacturing plants around the country. Don Joyce, Vice President of Sales and Marketing at Thermotech Corporation, presented “Reducing Cooled Water Waste.” Presenting the concept of incorporating trim cooling into a cooling system, Joyce walked his audience through the process of evaluating the need and potential benefit of a trim cooler. Reviewing the various types of trim coolers available, Joyce offered sage advice on finding the right trim cooler for all types of operation and weather conditions. Keynote speaker Leslie Marshall, Corporate Energy Engineer Lead at General Mills, presented “Compressed Air Heroes,” to the large assembly. Marshall shared the ambitious climate change and sustainability goals General Mills is pursuing. She was proud to tell the crowd that General Mills met their goals through the Department of Energy’s Better Building Program four years early and have saved \$6.2 million in their North American plants. Marshall emphasized one of her main focuses today is on fixing leaks, rather than just identifying them.
