As an industrial distributor for 65 years, C.H. Reed, Inc. has been providing ideas, concepts and sustainable solutions to help manage issues associated with three key areas of industrial plants: compressed air systems and equipment; assembly tools and ergonomic material handling; paint finishing and fluid handling equipment. Compressed air has always been a strong focus for C.H. Reed, and it’s a common thread running through all of its product families.
A culture change is in the air at Sullair, a pioneer in air compressor technology, as the company celebrates its 50th anniversary. A global manufacturer of rotary screw air compressors used to power air-driven industrial equipment and tools used in manufacturing as well as the energy, mining and chemicals industries, Sullair operates five manufacturing facilities worldwide.
QCAS provides service, sales, parts and rental solutions for plant air systems, medical air systems, compressed air treatment and nitrogen generating systems. The company prides itself on being client-focused with a commitment to respond to service needs 24/7. “Our relationship with clients involves more than us just selling equipment, parts and maintenance. We provide system auditing, training, testing and information about innovations in our industry,” says Michael McCulley, president.
Quite a number of worst-case compressed air scenarios have been encountered over the years but none may compare to the conditions that existed in a metal foundry somewhere in North America. For reasons you are about to discover, we will not reveal the name of this factory or its location, in order to protect the innocent from embarrassment.
The Department of Energy estimates that compressed air systems in the U.S. consume about 30 trillion Watt-hours of energy per year. Of all the energy used in manufacturing, compressed air systems have the greatest potential return for implementing energy efficiency practices, according to the DOE. One approach to access some of that return is to eliminate waste by producing compressed air efficiently and only in the amount demanded. Another approach is to leverage compressed air system data to assess the impact of any system changes on energy consumption and productivity.
During my forty years of involvement with distribution (companies that sell and service compressed air system products) as a Vice President of Sales and Marketing and Account Manager, I have witnessed a tremendous amount of change in the compressed air industry. As much as we like to reminisce about the good old days, it is quite apparent that the resources, capabilities and knowledge of distribution today are significantly better than ever before.
Sullair of Houston, one of the largest North American distributors of Sullair industrial and portable diesel compressors, loves a challenge. The company designs customized air compressor packages that fit the rough and rugged world outside the walls of an industrial plant. It builds air compressor solutions that operate efficiently in extreme, harsh environments around the globe. This includes offshore or marine environments, high or low ambient conditions—any environment where a standard air compressor will not operate safely or efficiently.
Production complains about frequent work stoppages due to air supply related problems. It wants a more reliable consistent source of compressed air. Maintenance says it will need to replace an older compressor with a new one to improve the reliability and stability of the system. Maybe purchase a bigger one than currently needed in anticipation of future increases in air demands. Management wants assurances a good return on the investment will be realized from the expenditure before making a financial commitment. For comparing and evaluating alternatives, a benchmark must be established to determine the cost to run the current system. An assessment must be performed to identify the saving’s opportunities and assign dollar values. Questions about the cost of the assessment and what is to be expected in return need to be answered.
This metal fabrication and machining facility produces high-quality precision-built products. Over the years, the plant has grown and there have been several expansions to the current location. The company currently spends $227,043 annually on energy to operate the compressed air system. This figure will increase as electric rates are raised from their current average of 9.8 cents per kWh.
Nestlé Beats the Heat: Innovative Air-to-Water Heat Exchanger Recovers Heat from Air-Cooled Compressors
When the topic of discussion is making ice cream, the first thing that comes to mind isn’t heat, but at Nestlé’s Ice Cream factory in Tulare, California, heat is recovered from air-cooled air compressors to heat process water. “Right out of the gate, everything is pneumatic,” explains Tom Finn, Project Engineer with Nestlé Ice Cream Division. “Air cylinders and air driven motors, the process piping valves which divert, route, stop/start, and mix process fluids, our packaging machinery including rejection, cleaning and vapor removal processes, all of these rely on compressed air.
Compressed Air Best Practices® Magazine interviewed Dr. Jay Varadaraj, (Managing Director) of ELGi Equipments Ltd. ELGi today is one of the world’s leading manufacturers of air compressors. Like most companies, however, it started with one ambitious person. My grandfather, Lakshminaickenpalayam Govindaswamy (this where the “L” and “G” in ELGi come from) was a bus driver for the British in 1918. He purchased one bus and proceeded to build a fleet peaking at 300 buses. He believed he was in the transportation business so he entered the airline business ultimately withdrawing however when this industry was nationalized.
