Rotary Screw Booster Advances for Blow Molding

By Manoj Purohit, Product Marketing Manager (High Pressure Air/Gases), Atlas Copco Compressors

Compressed air boosters are engineered to amplify medium-pressure air (90–150 psig) to high-pressure ranges up to 435 psig (30 barg) using oil-free rotary screw technology, IE5 permanent magnet motors and advanced VSD+ drivetrains for improved turndown and energy efficiency. By combining Class 0 oil-free air quality, synchronous PM motor performance (up to 97% efficiency) and intelligent controls, next-generation booster systems deliver higher flow stability, reduced specific energy consumption and seamless integration into existing compressed air networks.

R&D Labs Shifting to N2 Generation

By Dave Henning, Sales Manager, MCE Diversified Air

This article explores how on-site nitrogen generation, using PSA and membrane technologies, enables engineers to produce nitrogen on demand with greater control over purity, flow and pressure. It also highlights real-world applications and the operational benefits of improved uptime, reduced handling risks and lower total cost of ownership.

High-Altitude Mining and Steel Production in Peru

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine

Before CAGI data sheets were created, air compressor distributors and their customers could only go by the manufacturers’ claims. He found there wasn’t any uniformity to the numbers manufacturers put out, so making comparisons was challenging. Some compressed air manufacturers measured capacity from the bare airend, while others measured from the air compressor’s outlet.

Plastics Plant Audit Improves VSD Air Compressor Arrangement

By Ron Marshall, Chief Auditor, Marshall Compressed Air Consulting

Estimates based on the captured data show 567,000 kWh costing \$23,375 per year, while feeding an average of 240 cfm to the plant. Estimated savings for upgrading the VSD air compressor to higher efficiency and higher capacity, converting failing desiccant compressed air dryers to cycling refrigerated compressed air dryers and reducing wasted demand total \$9,160 per year, resulting in 39% lower energy use.

Sustainable Operations in Practice at Klöckner Pentaplast

By Roderick M. Smith, Compressed Air Best Practices® Magazine

In most of our factories, we have installed detailed energy monitoring systems at multiple points along production lines, including air compressors, chillers and lights. These systems feed into a digital dashboard that displays energy consumption throughout the factory. For data visualisation, we use dashboards that aggregate data collected via SAP from production lines and allows us to visualise the data at a high level.

ABC Compressors Supports Logoplaste Embedded Wall-to-Wall Sustainable Manufacturing

By Mike Grennier, Compressed Air Best Practices® Magazine

Logoplaste, based in Cascais, Portugal, introduced its embedded wall-to-wall manufacturing model to reduce waste and increase efficiency. The model also results in a more economically and environmentally sustainable method of production of rigid plastic packaging since it eliminates the need for a separate secondary packaging plant and the logistics associated with transporting empty bottles.

PET Plants Using Boosters for High Pressure Air

By Hank van Ormer, Technical Director, AP Energy

The use of high performance boosters to raise low pressure air (100 psig) to high pressure air (500-600 psig) for blow molders is very power efficient and offers good operating performance and reliability when well applied.

DOE Better Plants Partners Get Serious About Compressed Air Systems

By Robert Lung, BGS, with contributions from: Ed Willhite, Schneider Electric; Stephen Tankersley, Ring Containers; Marco Gonzalez, Waupaca Foundry; and Darwin Jaeger, Plastics Engineering Company.

Compressed air is used in all the company’s plants and is often the single largest energy end use within them. As a result, compressed air energy-saving measures are often replicable across the company and offer significant positive impacts. One area of focus is with compressed air leaks since they are “the best low hanging fruit to focus on and they always keep popping up and waste energy”.

Why a Centrifugal Air Compressor May Be the Better Choice

By Richard Huguenor, Business Development Manager for Oil Free Products at Sullair, LLC.

When selecting an air compressor for your manufacturing operation, the common choice is the industry-standard rotary screw compressor. Known as the work horse of compressed air machinery, the rotary screw compressor comes in a multitude of sizes and power levels. However, centrifugal compressors have seen some exciting technological progress in recent years and offer a wide range of pressures, flow and turndown. Long known for their longevity and durability, they offer higher efficiency, even qualifying for energy rebate programs offered by local utilities and all, notably, produce Class 0 oil free air.
