Industrial Utility Efficiency

Leaks

One of the best ways to reduce compressed air costs is to look for ways to reduce leakage flow, an unnecessary load that is a constant demand on the compressed air system. This flow is never-ending and occurs during production periods, and during quiet times at night or on weekends. Reducing the flow in a well-controlled compressed air system will result in the reduction of compressor energy consumption, usually by about \$1,750 per every 10 cfm, and often reduces pressure loss, allowing your machines to run better. This article discusses some recent experiences in using an acoustical imaging leak detector.

DOE Better Plants Partners Get Serious About Compressed Air Systems

Compressed air is used in all the company’s plants and is often the single largest energy end use within them. As a result, compressed air energy-saving measures are often replicable across the company and offer significant positive impacts. One area of focus is with compressed air leaks since they are “the best low hanging fruit to focus on and they always keep popping up and waste energy”.

Whiskey Distillery Compressed Air Study Saves Energy

A premium whiskey distillery was seeking to renew their compressed air system and meet their corporate mandate in making their production facility more efficient. The first step on the road to improvement was having their compressed air system assessed. This article discusses some of the findings of the system study, which saved significant energy, improved system reliability, and captured a significant utility incentive to help with the study costs and the cost of a new compressor.

Leak Detection Technology Transitions Toward Maintenance 4.0

Awareness and interest in leak detection only continues to grow thanks to a number of factors. What we have seen over the last 20 years is a more sustainable way of thinking, established international energy efficiency standards, reliable leak detection technology, and best practices to implement leak detection.

Saint-Gobain Makes Solving Sustainability Competitive and Fun

Challenging teams of employees to generate energy savings while having a good time in the process is the idea behind Saint-Gobain’s “Compress It,” which is the name given to the company’s competition and ongoing effort to reduce compressed air energy and costs. The initiative, which Saint-Gobain rolled out to manufacturing plants throughout North America in 2018, has been met with success. Compress It identified potential energy savings amounting to 26 Gigawatt-hours (GWh) of electricity and \$2.5 million.

Protect Profits with Compressed Air Leakage Best Practices

This article discusses leak assessments and the barriers to effective leak management. Some best practices will be discussed as suggested tips to help you get the most of your leakage reduction efforts. We all hear it time and time again, leakage reduction is one of the first things we can do to reduce compressed air system electrical costs. Yet almost every industrial compressed air system assessment finds high levels of leakage, and too often plant maintenance staff are fully aware they have a problem but fail to act.

Milk Products Plant Finds 52 Percent Potential Savings

A food processor was having compressed air problems, so they invited a compressed air auditor into their plant for an assessment and to help them size future permanent air compressors. The plant was experiencing low air pressure and detecting water in the compressed air lines despite having a desiccant air dryer. The auditor thoroughly analyzed the compressed air system production equipment and did end-use assessment and leakage detection. This article discusses the findings leading to a potential cost savings of 52% of the current level.

Culture Building with ENERGY STAR® Energy Treasure Hunts

There are many reasons why the U.S. Environmental Protection Agency (EPA) ENERGY STAR® Energy Treasure Hunts have proven successful in helping companies save energy and natural resources, but one that rises to the top is their ability to build a culture of energy efficiency throughout an organization.

Technical College Audit Finds Savings of $45,000 in Energy and Water Use

As part of an energy reduction effort, a Canadian technical college hired a compressed air auditor to do a leakage audit of their large campus, which houses over 30 mixed use buildings, including laboratories, research facilities, shops and classrooms. The audit found very few leaks, the reduction of which would achieve minimal savings; however, a few surprising items of interest were noticed during the study that showed very good potential for operating cost savings of 64% with an estimated \$45,000 per year in reduced energy and water costs. This article discusses some of the findings and how savings can be achieved on lightly loaded compressed air systems.

Everyone Wins with Tennessee Tech University Industrial Assessment Center Program

Launched in 2006, the TTU-IAC program provides manufacturers in the state with free energy, productivity, and waste assessments – including best practices for compressed air systems, and blowers and vacuum, as well as cooling towers and chillers. The assessments to date have provided manufacturers in the program with \$27.48 million in recommended cost savings, equaling 3.82 trillion British thermal units of energy savings.
