Magnetic Pickups Reduce Compressed Air Demand at Automotive Plant

By Nasr Alkadi, Ph.D., CEM, CSRM, Strategic Energy Management Consultant and Coach, CLEAResult

This article focuses on a project to replace vacuum cups with spring-return magnetic pickups for handling ferrous metal parts at an automobile assembly plant in Missouri. The application is most familiar in automotive stamping and body shop operations, but the lesson applies to any plant using vacuum cups to grab steel blanks, panels, brackets or formed parts. The original equipment in this case study used vacuum cups served by venturi devices.

Achieving Precise Powder Coating Control and Greater Productivity

By Sumit Kapde, Global Business Development Manager, Robotics and Proportional Valves, Emerson

When building powder coating solutions, it can be a challenge to optimize compressed airflow with minimum reaction time. Without this level of control, the coating thickness may not be uniform and transfer efficiency – the amount of powder adhering to the object being sprayed – may be low. The resulting overspray can waste powder material. The control of a powder coating machine — and the quality and efficiency of the application — depends on the performance of the valve block.

Front Row Motorsports Takes the Checkered Flag with Clean, Dry Compressed Air

By Mike Grennier, Compressed Air Best Practices® Magazine

At the paint booths, FRM team members typically use conventional High-Volume Low-Pressure (HVLP) paint sprayers to prime the chassis and car bodies. Paint pressure pots (also called paint tanks) feed paint to the paint sprayers. The compressed air system supplies air to the paint pots at a steady 65 psi. The tanks regulate air output for the sprayers at 12 to 15 psi in order to deliver the precise amount of paint to a given chassis or car body.

Networked Air Compressors Operate in Harmony at Automotive Manufacturer

By Stephen Parry, Bay Controls

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.

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.

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.

Control Panel Cooling Change Saves Compressed Air Electrical Costs

By Ron Marshall for the Compressed Air Challenge®

As a result of compressed air awareness training and a focus on energy management, two facilities in different parts of the world have reduced their compressed air demand substantially by removing vortex style cabinet coolers from some of their electrical panels and reworking the cooling systems. These facilities were previously unaware of the high cost of compressed air and how much could be saved if other methods of cooling were used. This article describes some of their efforts in demand reduction.
