Industrial Utility Efficiency

# Industries

Products manufactured at the 100,000-square-foot plant in Kentucky include columns, I-shafts, covers, keylocks, and other dressings, along with shifter applications, such as straight, tap-up/tap-down and gated shifters. In all, the facility supplies automakers with products used in more than 100 different applications, all of which are designed keep vehicles operating safely, smoothly and reliably.

## Unilever Ice Cream Plant Reduces Compressed Air Consumption with Pneumatic Energy Efficiency Module

Electricity and compressed air play an important role in the thermal and kinetic processes for everything from mixing and extruding the ingredients, deep-freezing to -13°F (-25°C), dipping into various chocolate coatings through to final packaging. Energy efficiency is therefore right at the top of Unilever’s list of priorities. As part of the Unilever Sustainable Living Plan, this global corporation has succeeded in saving more than \\$186 million in energy costs from efficiency improvements in production alone since 2008.

## Paper Products Plant Stands to Save with Compressed Air System Upgrades

The facility has a compressed air system consisting of four, 200-horsepower (hp) two-stage water-cooled lubricant-free reciprocating air compressors. The air compressors are controlled individually with local pressure switch controls connected to a common pressure sensing point. These air compressors have been operating since the mid-1960s and are very difficult and expensive to maintain because parts are scarce and service companies with experience servicing this type of air compressor are difficult to find.

## Tier 1 Automotive Supplier Saves Energy Upgrading Centrifugal Air Compressor Controls

A Tier 1 automotive supplier was concerned its compressed air system was not operating as efficiently as it could be. The situation called for a site visit and metering and evaluation of the company’s air compressors to generate a representative data sample that accurately captured the compressed air needs during typical production and non-production periods.

## Winpak Reduces Demand by 33% and Switches to Oil-Free Air Compressors

By making changes primarily focused on compressed air uses, Winpak, an international plastics products manufacturer based in Winnipeg, Manitoba, Canada, increased compressed air production capacity and reduced annual energy consumption by 33%. These benefits have been accomplished while the company was making the switch to lubricant-free compressed air to support product quality goals. This article discusses some of these changes and addresses measures that could be implemented in any compressed air system.

## IUE-CWA Labor Union Members Embrace Energy Treasure Hunts

Manufacturers familiar with the U.S. Environmental Protection Agency (EPA) ENERGY STAR® Energy Treasure Hunts initiative know it’s a great way to save energy and natural resources – as long as it’s done right – which is why some are turning to perhaps their best asset to achieve success: their unionized workforce.
