Air Compressor and Chiller Innovations at NPE2024

By Troy Dreier, Compressed Air Best Practices® Magazine 

NPE2024: The Plastics Show took place in Orlando, Florida, May 2024, and Compressed Air Best Practices® Magazine and Chiller & Cooling Best Practices Magazine were there to cover the highlights. This year’s conference drew over 50,000 registrants, including 15,000 from outside the United States. Filling both buildings of the Orlando Convention Center, the conference included zones dedicated to bottling, recycling and sustainability, material science, advanced manufacturing, mold-making and packaging.

PET Bottle Blowing Efficiency

Compressed Air Best Practices® Interviewed Dean Smith, iZ Systems.

The PET industry is in a state of flux right now. A number of new bottle blowing facilities are being brought on-line. They are in the “discovery” phase right now as they realize how challenging the required compressed air systems are to manage – from an energy efficiency standpoint. The average high-volume stretch blow molder (SBM) working with PET usually has 2,000 to 4,000 horsepower of installed air compressors with the related energy costs running between \$1 to \$4 million per year. This typically represents 35-40% of the facilities’ total energy bill.

Bottler Best Practices in California

By Creg Fenwick and Kyle Harris, Accurate Air Engineering

Bottling companies and breweries, in California, are benefiting from a three-step system assessment process aimed at reducing the electrical consumption of their compressed air systems. The three-step process reduces compressed air demand in bottling lines by focusing on open blowing and idle equipment, and then improves the specic power (reducing the energy consumption) of the air compressors.

Compressed Air Efficiency Opportunities in the Plastics Industry

By Dean E. Smith, iZ Systems for the Compressed Air Challenge®

As in most industrial categories, compressed air is critical to the operations of a plastics plant whether it is blow molding, injection molding, or other processes. The opportunities to improve supply side (compressor room) efficiency are similar to all industrial compressed air systems, but are even more prevalent in some plastics facilities, especially blow molding.

Double-acting Reciprocating Air Compressors for P.E.T. Bottle Blowing

By Donald J. Oitker

Most P.E.T. bottle-blowing machines require anywhere from 550 psig (38 barg) to 580 psig (40 barg) and an air flow of 247 cfm FAD (420 m3/hr) to 3700 cfm FAD (6290 m3/hr). The air compressor technology used most prevalently for this application is the double-acting, oil-free, water-cooled, reciprocating air compressor. With the higher pressures and air flows that are required, the P.E.T. bottle blowing market is a strong niche market for the double-acting oil-free reciprocating (piston) compressors.

Bottling System Air Recovery at NPE 2009

Compressed Air Best Practices

The NPE2009 international plastics showcase was held June 22-26 in Chicago’s McCormick Place. While attendance was down from NPE2006, the preliminary total of visitor registrations numbered 44,000. Sustainability and energy efficiency was a prominent topic in the booths of exhibitors. Manufacturers of compressed air and injection molding equipment had many developments with Sustainability to show the visitors to NPE2009.
