Industrial Utility Efficiency

# System Assessments

This article discusses some experiences in using cellular connected data loggers to perform a compressed air assessment during a time when travel was restricted. While not ideal, this exercise identified huge savings for this customer.

## Re-engineered Compressed Air System Scores Perfect “10” at PC Forge

Since completion of the system upgrade in the fall of 2020, PC Forge is on track to save an average of 1.9 million kWh and $266,000.00 per year in energy costs – and increase the production capability of its forging operation by 40%. The project also achieved a one-year payback with a \$245,000 incentive from Government of Ontario’s utility Independent Electricity System Operator (IESO).

## Industrial Central Vacuum System Evaluations: Part 2 Audit Measures

Operating the vacuum system at higher levels (then necessary) affects the needed volumetric flow to compensate for leaks. This required compensation of volume (ACFM) must be added to the nominal production flow demand. The ambient air leak into the system will expand to the highest vacuum level, which is known as the “Expansion Ratio.”

## Solving Predictive Maintenance and Sustainability Challenges Through Digital Transformation

The industrial internet of things (IIoT) and industry 4.0 have digitally transformed the way facilities operate, enabling processes that are smarter and more efficient than ever before. But digital transformation is still new to some and may seem abstract or ambiguous. In actuality, it’s quite the opposite.

## Industrial Central Vacuum System Evaluations: Part 1 Measurement

What is vacuum as used in the manufacturing/industrial sector? The clearest answer is – a contained space with gaseous pressures much less than surrounding atmospheric pressure. Atmospheric pressure (ATM) is expressed in many units of measure. At room temperature a cubic foot of contained air at sea level – the random movement and molecular impact on the walls of the containment vessel equal a force of 14.7 psia for every square inch of the walls.

## A High-tech Way to Extend Your Reach to 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.

## Cleaning Products Plant Innovates and Saves

As part of its ongoing corporate initiative to find ways to reduce its energy bills, and the costly impact on the bottom line, a cleaning products plant, located southwest of Chicago, recently focused on improving their compressed air system operation. This company is a global leader in water, hygiene and infection prevention solutions and services. This article discussed their efforts to improve the operation of their compressed air system by implementing an innovative compressed air monitoring and control system.

## Pure Gas Testing-The Benefits of Point of Use Sampling

Regular testing of pure gases helps to ensure the safety of consumers and of end products. Whether the pure gas is used directly for medical patients, or in the manufacturing of food, beverages, or pharmaceutical products, quality is of the highest importance. Inadequate levels of purity or unsafe contamination can be detrimental to the products or consumers.

## Both Metal and Plastic Pipe Necessary for Compressed Air Applications

This article will focus on the suitability of plastic pipe systems as well as joining methodology in compressed air applications.

## The Gentex Journey to Reliable Energy Conservation - 3 Levels of Compressed Air Systems

The information contained in this article, will help the operator to assess his/her systems, and identify where these systems fall within a three-level category. There are many ways, and opportunities to make a compressed air system produce reliable and good quality air. The three levels discussed here could also be characterized as a “continuous improvement plan” which can be achieved over the course of time, and with the occasional investment of money.

## Compressed Air Dryer Key Performance Indicators

The purpose of this article is to point out the key performance indicators (KPI’s) that can assist in maintaining the performance and troubleshooting of compressed air dryers. The most important KPI to monitor is the pressure dew point (PDP) of the compressed air exiting the dryer(s). The PDP of the compressed air should be monitored at the discharge of each dryer and downstream of where the compressed air from multiple dryers converges.
