Industrial Utility Efficiency

Compressor Controls

Hitachi Astemo’s efficiency gains will turn into significant cost savings. In this article we outline the savings reported by the client since the changeover was complete. It shows a sizeable reduction in energy costs, air compressor energy costs and maintenance costs to the tune of 21.95%, 24.14% and 24.14%, respectively. Total operating costs to date have dropped from \$1,277,394 to \$941,959 with the new system a decrease of 26.25%.

The Industrial Sustainability 2025 Best Practices EXPO & Conference Show Report

Compressed Air Best Practices® Magazine launched its first event in Europe, the Industrial Sustainability Best Practices EXPO & Conference, in June 2025 in Barcelona, Spain. Designed to educate and connect factories and specifying engineers on the optimization of industrial compressed air, vacuum and cooling water systems, the event featured 12 hours of conference sessions, exhibits and the first Compressed Air Challenge training to take place in Europe. 

The Effect of Increased Storage Capacity on Load/No Load Air Compressors

Fixed speed, lubricated, rotary screw air compressors offer three different part-load control methods: inlet modulation, load/no load and variable displacement. Over the years, load/no load has become the predominant control method offered by fixed-speed air compressor manufacturers. 

How IoT and AI Transform Compressed Air System Management

In the rapidly evolving landscape of industrial automation, the integration of internet of things (IoT) and artificial intelligence (AI) is reshaping production and utility management. Compressed air system management stands out as an area undergoing significant transformation. Compressed air systems are critical in many industries, serving as a power source for tools, machinery and various processes. 

A Quarter Century of Positive Change at Automotive Supplier’s Mexico Plant

Today, leading automotive makers rely on the plant for parts used to produce some of the most sought-after vehicles. Additionally, the nearly 600,000-square-foot manufacturing facility achieved ISO 50001 certification in 2021. Here’s a look at how the plant grew for the better over more than 25 years – and its compressed air system along with it. 

Remote Monitoring Takes Off for Aerospace Manufacturer

In the absence of the control system, the air compressors were loading and unloading according to pre-set pressure bands, which forced the system to operate at higher pressures and run inefficient combinations of compressors in order to effectively match air demand. When switched on, irrespective of air demand, the control system was able to control all compressors on a single, tight pressure band and efficiently match output with demand.

Wonderful Pistachios & Almonds™ Optimizes Piping and Air Compressor Automation

The Wonderful Pistachios and Almonds campus in Lost Hills, California is a manufacturing facility that processes and packages pistachios and almonds for the consumer market. Food processing requires extensive use of compressed air to control multiple applications ranging from actuators, valves, optical sorters, packaging equipment and plant maintenance operations. The campus has its peak season during harvest in late August/early September, but processing and packaging operations take place year-round.

AZEK Compressed Air Project Enhances Reliability While Saving Energy

The AZEK Company is a producer of durable and low maintenance building materials, and like many manufacturers, it found its compressed air system to be time consuming and expensive to keep maintained. But that changed after the company replaced its outdated and faulty compressed air system with a new design that includes technically advanced air compressors, dryers, receiver tanks – as well as controls to provide better control of the entire system and achieve optimal performance.

Chemical Plant Compressed Air Audit Using Cloud-based Software

A large chemical plant in Celje, Slovenia, planned to retrofit a kiln used to produce titanium dioxide. To make space for the new equipment related to the retrofit, the plant needed to relocate its high-pressure compressed air system feeding an adjacent pressing process used to dry the material before firing it in the kiln. However, a comprehensive compressed air audit using cloud-based software showed the plant did not need to relocate the system.

Networked Air Compressors Operate in Harmony at Automotive Manufacturer

When an automotive company added a new 200-horsepower (hp) rotary screw air compressor and accompanying dryer to a satellite building at its Chicago-area assembly plant, it needed a cost-effective way to integrate the equipment into its existing compressed air network. Doing so would allow plant personnel to easily monitor the air compressor’s performance and ensure it operates in harmony with the plant’s centrifugal air compressors. Importantly, it would contribute to efficient and reliable air compressor operation at all times.

ISO 50001: How Manufacturers Can Achieve a Low-cost and Low-carbon Future

For an organization to prove that it meets the standard it has to undergo a management system audit, either internal or external. The question, therefore, is how can those utilizing compressed air effectively evaluate their assets’ performance as part of an ISO 50001 energy management system and, in doing so, grow their bottom line and minimize their negative environmental footprint.
