Industrial Utility Efficiency

Technology

Word is beginning to filter out about the 2022 changes to the ASHRAE 90.1 energy efficiency standard, and the changes it promises to bring to how compressed air systems are specified, commissioned and maintained. More specifically, the industry is learning about section 10.4.6 of 90.1, which is the first time the standard has included a section on compressed air. 

The 2023 AICD Show Report

“The AICD enjoyed a record turnout of exhibitors,” said Jeff Brennan, President, AICD. “We’ve added over 20 member companies this year and our membership again has delivered a strong turnout at this year’s event.” Participating distributor members and guests enjoyed a few days of networking events, trade show, speakers, the AICD Golf Tournament and more.

Evaluating Air Compressor Cooling and Heat Recovery Part 1

This is a two-part article looking at factors impacting decisions on whether to use air or water-cooled air compressors. It also provides heat recovery guidelines for both situations. Part 1 will provide a brief history on air compressor cooling, a review of cooling water sources and costs, and some cooling cost comparisons between air and water-cooled air compressors.

Good Things in Store as Hitachi Global Air Power Takes Shape

When Hitachi Industrial Equipment Systems Co., Ltd. (HIES) announced Sullair, Hitachi, and Champion Compressors (Australia) have come together under the umbrella of Hitachi Global Air Power (HGAP), many wondered what it would all mean. 

Ceramics Plant Deploys a New Air Compressor Heat Recovery System

An air compressor is synonymous with an electric heater – providing compressed air as a side effect. 85-90% of the electrical energy taken in by the air compressor is converted into heat, while the maximum efficiency of compressed air generation is less than 10%. In air compressor heat recovery systems, the focus is on capturing the heat energy contained in the oil, as up to 80% of the energy extracted from the power plant is found there.

A Deep Dive into Dew Point Measurement in Compressed Air Systems

In extreme situations, raw battery materials can react with water molecules in the air, causing explosions. In semiconductor development, wafer manufacture requires a highly controlled environment and precise data on the manufacturing environment. Moisture can cause defects in the microelectronic components, impacting their functionality and reliability. For each application, a fast response time allows for quick detection of dew point changes, which can be addressed before they cause damage to the product or equipment.

Centrifugal Air Compressor Maintenance: The Importance of OEM Parts

Aftermarket genuine parts ensure that the compressed air system will continue to meet the requirements it was engineered to achieve. Replacement parts must fit the compressor correctly so that operation continues to function properly. Parts that are not fitted properly could affect the function of the unit downstream.

Hannover Messe 2023 Show Report

The 2023 Hannover Messe was held April 17-21 at the Fairgrounds in Hannover, Germany. I have been visiting this event, since 1992, and it’s great to see old friends, new companies and the latest company and technology developments of firms in the compressed air industry. This article will provide readers with a sampling of compressed air technologies seen. 

Smart Pneumatics Play Big Role in Meeting Industrial Sustainability Goals

Pneumatics and the generation of compressed air accounts for about 10% of a typical facility's energy consumption. That number could be much lower, but because of leaks and poor air pressure regulation, a surprising amount of energy is wasted in the process. Yet, most manufacturers are not taking full advantage of smart pneumatic technologies or data analytics to improve energy efficiency. By installing connected pneumatic solutions in their plants, manufacturers can continuously collect critical data to understand where energy is being wasted and make informed decisions to optimize energy consumption. 

Food Processor Conserves Energy with Compressed Air System Audits

A focus on sustainable products and packaging, in combination with a passion for quality, has resulted in considerable growth for the firm. Plans to add production lines at facility #1, in turn, drove the need to address the plant’s faltering compressed air system.

Tank Applications in Central Cooling Systems – Tankless Systems

This article will be of particular interest to industrial system operators unfamiliar with tankless (primarily closed) systems who may be considering either installing new systems without tanks or removing existing open tanks.  The topics covered step through an understanding of tankless systems while also including tank system pointers and insights on converting systems with tanks into tankless systems.
