Industrial Utility Efficiency    

System Assessments

This major mill complex upgraded their compressed air system and thereby eliminated $500,000 in annual rental compressor costs, reduced annual cooling-water costs by $500,000, and reduced electrical energy costs by $135,000 per year.

Chillers

A manufacturing site’s central utility plant (CUP) provides 24/7 cooling for critical R&D laboratories, critical manufacturing processes, data centers and office space. Over a period of several years, campus growth had significantly increased facility energy consumption, raising costs dramatically. Simultaneously, the host state enacted a legislation to deregulate utilities, a move potentially doubling the cost of electricity.

Evaporative Cooling

It is widely recognized that compressed air systems account for ten percent of all electricity and roughly sixteen percent of U.S. industrial motor system energy use. Seventy percent of all manufacturing facilities in the United States use compressed air to drive a variety of process equipment.

Heat Recovery

If you enjoy the occasional beverage from an aluminum can, there’s a decent chance the can was made by Ball Corporation, a container manufacturing giant with facilities across the world. The company’s facility in Saratoga Springs, New York, services beverage companies throughout the northeastern United States. The plant operates four production lines producing millions of aluminum cans per day.

Free-Cooling

Process cooling system applications experiencing constant production loads generating high process fluid temperatures are particularly good candidates to take advantage of low ambient temperatures. Low ambient temperatures can be used as a “free” energy source, replacing the electricity required to run refrigeration compressors, in what is known as a free-cooling chiller system.

Cooling Controls

Pepco Energy Services’ (PES) Midtown Thermal Control Center (MTCC) in Atlantic City, New Jersey, sells chilled water and steam to multiple Atlantic City casinos, Boardwalk Hall and Pier Shops. PES is also responsible for stand-alone remote heating and cooling plants for the Atlantic City’s major casino’s as well as the Atlantic City Convention Center including its 2.4 Mw solar array.

Water Savings

ElectroCell Systems, Inc., manufactures a system for commercial, industrial and institutional facilities that is applied to conventional water-cooled chilled water plants. The system significantly improves efficiency in water and energy use with paybacks in the 2.0 to 3.5 year range. The system is not a substitute for chemical treatment; rather it is a Condenser Water Efficiency system, engineered specifically and solely to increase water and energy efficiency by addressing the uniquely challenging demands that exist only in the condenser water loop.
Manufacturers are under continual pressure to control costs without affecting operations or worker comfort and safety. Because energy ranks as one of the largest operating expenses, improving energy efficiency of mechanical cooling systems is one of the best ways to reduce operating costs. In a typical water-cooled chiller plant, the chiller itself accounts for most of the energy consumption. That’s why improving chiller efficiency is critical to controlling operating costs.

Hydronic balancing in industrial heating and cooling systems is an often overlooked final step in startup and commissioning of new and modified hydronic systems.  Insisting on a complete system balance upon startup of a new or modified system is an inexpensive insurance policy for any design engineer or installation contractor to protect their reputation against a system that is not performing to design conditions.  There are several methods of hydronic system balancing utilized in commercial and hospitality buildings, however, they are rarely found in the manufacturing and industrial environments.
While the chiller is the heart of a chilled water system, its support system of components and controls are equally critical to maintain and manage to ensure the highest system efficiency levels are attained. Emphasis is often placed on the chiller since it is the most visible and typically the highest energy element of a chilled water system. Yet, if you look beyond the flanges, there’s an opportunity to improve delivery of chilled water to the airside or process loads and maximize system efficiency.
Anecdotal reports from users of Tower Tech cooling towers across the U.S. have indicated the Tower Tech design provides substantial savings to the customer both in terms of lower chemical treatment requirements and substantial water savings. There are a number of mechanisms by which the Tower Tech design facilitates efficient, lower cost water treatment and usage. A few are described in this article.
Controlled cooling is an essential part of manufacturing polyethylene stretch film.  The process starts with granulated polyethylene raw product with very low strength, and develops thin, clear, strong film used in a variety of applications.  It does this by melting, extrusion, “casting” and winding.  See Figure 1 for a typical system diagram.  “Casting” is forming and cooling at the same time.  The extruded polymer is stretched and cooled on large, chrome-plated rollers with cooling water flowing inside.  Thinner film is for manual use, like wrapping around food products.  Thicker, stronger product is made for machine use, like automatically wrapping pallets of concrete bags.
Chrysler’s Technology Center (CTC), located in Auburn Hills, MI, is home to some fourteen thousand employees responsible for keeping the automotive giant in motion. Completed in 1991, the complex is essentially a small city, encompassing 5.3 million square feet situated on over 500 acres. In addition to corporate offices, the facility houses a full laboratory level of various wind tunnels with thermal testing capabilities, a 1.8-mile evaluation road, a noise/vibration facility, an electromagnetic compatibility center, an environmental test center (able to create rain, snow and extreme temperatures), and a pilot production plant.
Cooling towers dissipate both ambient and process heat in most large manufacturing facilities. These structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. Problems with efficient heat transfer, equipment protection and pathological risks to employees can most often be traced back to an issue with suspended solids. These solids can originate in the process, in the piping, from the atmosphere or from internal biological growth.
