Industrial Utility Efficiency

Technology

The 2019 WEFTEC Technical Exhibition and Conference was held September 23-25 at McCormick Place in Chicago. The event featured 148 technical sessions, 27 workshops, 16 mobile sessions, seven local facility tours and 1,000+ exhibitors.  Both Blower & Vacuum Best Practices and Compressed Air Best Practices® Magazines were pleased to be in the literature bins at the 2019 WEFTEC!

SHOW REPORT: The Inaugural BEST PRACTICES EXPO & Conference

Held September 16-19, 2018 in Chicago, the first-ever event drew 750 attendees who came together to learn and share ideas about the countless ways to achieve efficiencies with compressed air, blower, vacuum and cooling systems – and in the process – save energy and improve profitability.

Proper Blower System Design for Variable Wastewater Depth Processes

Most blower applications for wastewater treatment are for conventional activated sludge aeration. The water level is typically constant, and pressure variations are usually less than one psi. There are other applications, however, that undergo significant variations in water level. These processes present challenges, but they can be accommodated with proper blower system design.

When Planning Efficiency Upgrades, Don’t Ignore Vacuum - Reduced Power Consumption and Utility Incentives Drive Cost Savings

Electric utility incentive programs encourage industrial and manufacturing companies to reduce power consumption by paying part of the cost to upgrade to more efficient equipment. It’s a great concept, but many customers only go after low-hanging fruit, such as upgrades for lighting or air compressors, and go no further.

Republic Manufacturing Delivers Food Grade Blower & Air Knife Systems

Blower & Vacuum Best Practices interviewed Republic Manufacturing VP of Sales & Marketing, Rich Leong.

Our line of regenerative blowers, also known as side channel blowers, are for vacuum or compressed air applications in both horizontal and vertical mounted positions. Airflow capabilities range from 50 to 776 CFM, vacuum capabilities from 47" to 236" of water (1.7 psi to 8.53 psi) and pressure capabilities up from 47" to 307" of water (1.7 psi to 11.09). TEFC electric motors are cUL and CE certified and come in single and three-phase, dual frequency and multi-voltage versions for worldwide applications. Horsepower ranges from 1/2 to 40 HP (from 0.4 to 30kW).

Rotary Lobe Blowers, Nozzles and Air Knife Save $248,000 in Energy

A metal producer, in the Midwest, spends an estimated $2.4 million annually on electricity to operate their compressed air system.  The current average electric rate, at this plant, is 5.5 cents per kWh, and the compressed air system operates 8,760 hours per year. This system assessment recommended a group of “near-term” compressed air demand reduction projects and then a group of separate “longer-term” projects focused on optimizing the air compressors, the controls and the heated desiccant compressed air dryers. The near term demand-reduction projects...

Suttero Bazenheid Advances Meat Processing to Energy-Efficient Centralized Vacuum System

Energy for the entire Ernst Sutter AG company – and consequently the Suttero Bazenheid premises as well – is generated via hydropower. In addition, around 75% of the energy from refrigeration is also used to generate hot water. When creating vacuum for packaging, Suttero Bazenheid relies on a centralized vacuum system from Busch. This is significantly more energy-efficient in operation than decentralized vacuum supplies on individual packaging machines. As a result, Ernst Sutter AG has created a production plant that corresponds to the latest standards, both from a technical and ecological perspective. 

Darigold Utilizes Vacuum in Cheese Processing

Blower & Vacuum Best Practices interviewed Darigold’s Sunnyside Plant’s Technical Manager, Tom Rouleau.

Today, we manage one of the largest dairy co-ops in the United States. Our dairy farms and plants are truly awe-inspiring and efficient facilities. Our butter is made by one of America's only European-style vacuum churns, which makes butter with fewer air bubbles. Having the latest technology also helps Darigold produce less waste, fuel consumption and lower environmental impact.

High Vacuum Solutions for European X-Ray Free-Electron Laser

The European XFEL is a new international research facility, where 12 European countries participate. The non-profit society European XFEL GmbH is responsible for the construction and operation of the X-ray laser. DESY (Deutsches Elektronen-Synchrotron), one of the leading centers for the investigation of the structure of matter worldwide and a long-term partner of Pfeiffer Vacuum, is the main share- holder.

Calculating Most-Open-Valve Aeration Control

Most-Open-Valve (MOV) can be a cost-effective way to optimize aeration energy. It can also be a confusing and troublesome addition to a process automation project. In my experience MOV is the least understood aspect of aeration control. This article will shed light on MOV, the process and energy impacts and why it’s worth the trouble.

Rotary Screw Vacuum Pumps Benefit Meat Packaging Plants

Meat packaging plants have long used vacuum pumps as a way to remove air and reduce the amount of oxygen in their products’ plastic packaging. Vacuum packaging extends the meat’s shelf life while protecting its flavor and exposure to outside elements, such as freezer burn and bacteria.
