Comparing the energy consumption of two chillers shows that instead of saving $400 per year in parts costs, a less-expensive filter increased annual energy expense by nearly $5,000. Headline indicator lights and similar meters and alarms. These allow the user to view an asset and dig down in the hierarchy to view trends from the plant down through a single asset. “What we see today with CMMS or EAM applications is that the information is much closer to real time than it was just a couple of years ago,” says Anders Lif, global industry director of manufacturing and logistics for IFS World Operations (www.ifsworld.com), speaking for IFS North America. OEE, which was in the past a lagging indicator of plant uptime and productivity, is now being used as an almost instant indicator of production-line performance. With operations and maintenance personnel increasingly working together, he says, “Business applications and CMMS sys- tems are moving very much toward the same set of rules operators live by in the SCADA [supervisory control and data acquisition] environment.” For that reason, he sees IFS customers seeking both more integration with factory floor systems and KPI-oriented displays. Systems also have added features for better management of maintenance and, specifically, condition data, such as triggering an alarm or message (on-screen, e-mail, text message) if asset conditions exceed upper or lower control limits, or simply triggering a preventive maintenance (PM) routine if all is well. They can trace multiple variables for a piece of equipment and support Boolean “and/or” logic to configure and display combined indicators. Users also can drill down in the system to validate that when an alarm triggers, it’s not a system error, before responding. This type of user interface provides “just what’s important right there in the browser,” says Paul Stamas, vice president if information technology at Mohawk Fine Paper, Cohoes, N.Y. (see sidebar on p. 26). “If a dial creeps up into the yellow zone, we know we need to view that item in more detail, and think about this valve or that motor, or do some preventive action that will be right behind that dial in the interface. It’s not so much about an event; it’s more about continuous monitoring.” Mohawk chose a system from Infor (www.infor.com) for its maintenance department, and is considering upgrading to its new Asset Sustainability Edition to perform con- 01/2006 01/2006 01/2006 02/2006 02/2006 02/2006 03/2006 03/2006 03/2006 04/2006 04/2006 05/2006 05/2006 05/2006 06/2006 06/2006 06/2006 07/2006 07/2006 07/2006 08/2006 08/2006 08/2006 09/2006 09/2006 10/2006 10/2006 10/2006 11/2006 11/2006 11/2006 12/2006 12/2006 12/2006 01/2007 01/2007 02 /2007 02 /2007 02 /2007 03 /2007 03 /2007 03 /2007 04 /2007 04 /2007 04 /2007 ColdWaveTM Refrigerated Dryers wring the nasty oily water out of compressed air systems to deliver pure, clean, dry compressed air to your air-powered operations.
