Software Drives OEM Toward Efficiency and Energy Savings ABB designed software for its ACS800 drive so Curtis-Toledo could improve the operation of its rotary-screw compressors. The customized software can control the system pressure, air delivery, oil temperature and duty cycle directly from the drive. Author: John Wilmes, ABB Inc.	06/23/2005
Process engineering: Dryer provides a concrete lesson in control Removing water or moisture from a liquid stream is a critical operation in many processes. Liquid stream dryers commonly contain either molecular sieves or adsorbents; during the last 20 years, the use of molecular sieves has become much more common.
