CMMS and critical assets With Summit Ultima there are no puzzles to solve when it comes to choosing the best lubricant for your air compressor. When it comes to oil compatibility, oxidation resistance, and extended drain intervals, Summit Ultima removes all guesswork. Summit Ultima is compatible with virtually all OEM lubricants on the market today. Additionally, Summit Ultima will continue to provide superior service, protecting your compressor when other lubricants will start to sludge and produce varnish, even in the harshest of conditions.

Box 131359 • Tyler, TX 75713 • 800.749.5823 • www.klsummit.com 30 www.PLANTSERVICES.com Most CMMS packages have priority fields to prioritize maintenance work. Almost every vendor includes a field for asset criticality on the asset master file, as well as a time-based priority on the work order. Some have a check box or a numeric field for jobs that have a health, safety or environmental impact. Many also provide one or more user-definable priority fields that give greater flexibility to define criticality. Vendors have ways to manipulate and present them to help you make best use of these fields. The simplest approach is to sort and filter work orders based on one or more priority fields. Comprehensive packages combine priority fields in simple ways, such as multiplying them together. The most sophisticated packages allow building a priority ranking by weighting factors such as asset criticality and time-based priority as well as non-priority fields. Some even have a user-defined algorithm for determining a scheduling priority. A sophisticated feature on a few CMMS packages is the ability to develop a scoring system for ranking asset criticality with: • Multiple user-defined questions for scoring failures in terms of output quality, asset performance, health, safety and environmental impact • Defined criteria, severities and scoring algorithms • Boolean logic to determine criticality based on impact severities • Calculated probabilities of failure and relative risk • Schedule or filter alarms based on criticality ranking or relative risk.
