An Overview of Medical Air Packages

By Shannon McAfee, Pattons Medical

The air is delivered through a distribution piping system that ends with a medical air outlet within the room. Outlet requirements per room are governed by American Institute of America (AIA) Guidelines for Design and Construction of Hospitals and Healthcare Facilities. Equipment is plugged into the medical air outlet to treat the patient. Many studies have been done determining the load required for medical air compressors. The sizing can be calculated using several methods.

How to Keep Reverse Pulse Dust Collectors Operating Efficiently and Reliably

By Ron Marshall, Marshall Compressed Air Consulting

Reverse pulse type dust collectors often represent a challenge to compressed air energy efficiency, and sometimes throw a wrench into the works by causing huge air pressure fluctuations, high transient flows and just plain large leaks. This article discusses this type of dust collector, often installed in food processing plants, and gives some real-life examples of problematic installations. Some suggested measures are mentioned to ensure your dust collectors keep running in a trouble-free manner.

SumiRiko Tennessee Saves Energy & Boosts Sustainability with Compressed Air System Upgrade

By Mike Grennier, Compressed Air Best Practices® Magazine

In a strategic approach to improving its management of compressed air, the company initiated an upgrade of its compressed air system at its Midway plant. In so doing, SumiRiko Tennessee saves 2.1 million kWh and \$100,000 in energy costs per year at the plant.  Additionally, lower energy use resulted in the reduction in CO2 of 800 tons per year. With a utility rebate, the project paid for itself within two years.

Automaker Saves $600,000 Yearly In Energy Costs & Improves Compressed Air System Reliability

By Pascal van Putten, VPInstruments, and Tyler Costa, ALD, Inc.

The project, which also involved the addition of a booster air compressor and receiver tank – along with the installation of an important pressure control valve – gives the automaker the ability to run fewer centrifugal air compressors during peak production. In so doing, the plant saves nearly 6.1 million kWh and more than \$600,000 per year in energy costs. The project also qualified for a \$369,374 rebate from the local utility, resulting in a six-month project payback – all while improving system reliability.

Outsourcing Compressed Air Gives GKN Sintered Metals Peace of Mind

By Jason Onyshko, Total Equipment Company

With an eye toward strengthening its competitive edge, GKN opted for a new approach for the compressed air it uses to power metal molding machines in addition to a variety of other applications at its manufacturing facility. After careful analysis and planning with the Total Equipment Company located in Coraopolis, Pennsylvania, GKN opted to move beyond its aging compressed air system – and instead – outsource compressed air as a utility. Doing so allowed it to free up valuable floor space, while also achieving peace of mind since it can now count on a fixed cost for a reliable compressed air supply for years to come.

Profile: Case Controls and Centrifugal Air Compressor Management

Compressed Air Best Practices® interviewed Lou York (Director), Devin Sullivan (Vice President of Engineering) of Case Controls.

By Mike Grennier, Compressed Air Best Practices® Magazine

Often, multiple centrifugal air compressors are set up to simply react to air demand, which requires the system to not only meet the new demand, but also make up for air depleted in the main header. This typically results in too much supply, which results in bypassing the air to atmosphere. The result is wasted energy use.

Capital & Maintenance Cost Avoidance When Metal Grinding Loads Rise

By Hank van Ormer, Air Power USA

Plant personnel had experienced ongoing problems with its process grinder performance due to unstable compressed air pressure. This created potential problems in terms of product quality. Grinders do not work properly without the proper pressure. Additionally, plant staff wanted to address these concerns, prior to a proposed 30% increase in production, and suggested raising the header pressure from the current operating pressure of 98 psig to 125 psig. The thought behind this was if the pressure from the header to the grinder process was dropping to 63 psig, then raising the pressure to the process would give the grinders enough pressure to work through higher peak production times.

Lessons Learned in Rebar Steel Mill Compressed Air System Project

By Tim Dugan, P.E., Compression Engineering Corporation

The steel mill in this article is a rolling “minimill,” a facility that melts scrap recycled steel and produces rebar for the construction industry. It fits in SIC code 3310. There are many plants like this all over the world, providing an environmentally sound service and product for their local community. They recycle waste steel from local sources and support local infrastructure projects with rebar, using electricity generated locally.

A Case for KPI Measurement in Compressed Air Management

By Ron Marshall, Marshall Compressed Air Consulting

All industrial facilities use some form of compressed air, and in most, the air compressors consume a significant amount of the total energy bill. A facility with a good energy management system is likely to identify their compressed air system as a significant energy user (SEU). If the facility were using an energy management standard, such as ISO 50001, they would be required to assess and track the energy consumption of all their SEU’s. In the case of the metal processing facility, they were measuring the output of more than 250 devices within the plant, including building heaters, RTU’s, dust collectors, and also tracking the consumption of their electricity, natural gas and water.
