Cooling Tower Direct Drive Motors Lead to Energy Efficiency Gains

By Sean Mullins, Product Manager – Laminated Frame Motors, ABB

Across industries, operators are adopting cooling tower direct drive (CTDD) motor technology. In particular, permanent magnet (PM) direct drive motors are delivering measurable improvements in efficiency, cleanliness and maintenance reduction. The change is more than a component swap; it represents a new approach to cooling tower design that reduces operating costs, supports environmental goals and improves reliability.

Nestlé Beats the Heat: Innovative Air-to-Water Heat Exchanger Recovers Heat from Air-Cooled Compressors

By Chiller & Cooling Best Practices Magazine

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.

Evaluating Air Compressor Cooling Systems

By Air Technology Group Hitachi America, Ltd., Industrial Components & Equipment Division

As the population continues to grow in the United States, industrial water use will need to continue to fall to help offset the increases in public-supply water use. Water-cooled compressed air systems provide an opportunity for sustainability managers to reduce associated cooling water consumption and costs. If switching to air-cooled air compressors is not possible, understanding the costs and the alternative types of liquid cooling systems is important.

Air Compressor Heat Recovery

By Dr.-Ing. Uwe Kaiser, Research & Development Manager, BOGE Compressors

When compressed air is generated, heat is inevitably produced as a by-product. Anyone looking to enhance efficiency can use this heat and increase the efficiency of compressors to about 95 percent as a result. To achieve this, there are easy-fit heat exchangers which can be fitted to existing air compressor stations. This investment often pays for itself within less than a year.
