Cooling large buildings typically requires the use of air- or water-cooled chillers that produce chilled water, which then cools the air. About 39% of buildings over 100,000 square feet use chilled-water systems employing various refrigeration compressor designs.

Intelligent process cooling describes an approach to cooling in beverage production and packaging that moves beyond evaporative cooling towers and the use of traditional central chiller systems that rely on ammonia as a refrigerant. Unlike traditional methods, it intelligently matches process cooling systems to individual cooling loads without an evaporative process or the use of ammonia to gain verifiably better results in energy efficiency, water use, and safety.
Long known as water hogs, resistance welders are widely used in factories that manufacture products made from sheet metal and wire. Sub-categories of the resistance welding process include spot welding, projection welding, seam welding, butt welding and flash welding. An adequate flow of cooling water is one of the most important variables of the resistance welding process, and the typical machine requires 2 to 3 GPM of water per cooling circuit.  
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.
Air compressors are very effective heaters. Over eighty percent of the energy input from the motor is converted into compression heat. That heat must be rejected from the compressor package in a way that maintains a variety of temperatures in a reliable manner. The laws of physics demand that the air temperatures go up with compression.
No matter what your application, there is a single formula for determining the size of chiller you need. There also industry-specific, rules-of-thumb for chiller sizing. These may vary depending upon the application. These guidelines and formulas may be used for sizing chillers for plastic process cooling applications.
Heat recovery opportunities have resulted in the largest amount of savings of our common projects our industrial energy management teams have implemented.  It is not the easiest type of project to implement but the amount of savings and the reduction of emissions makes this project very worthwhile.
Market demand for plastics machinery continued to grow in the third quarter of 2014, according to statistics compiled and reported by SPI: the Plastics Industry Trade Association’s Committee on Equipment Statistics (CES).
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.
Chiller & Cooling Best Practices interviewed Michael Jones, Corporate Energy Team Leader, from Intertape Polymer Group (IPG).   Intertape Polymer Group (IPG) is a manufacturer of tapes, films, woven fabrics, and complementary packaging systems for industrial and consumer use.
