Predictive Maintenance

Predictive Maintenance (PdM) techniques are designed to determine the condition of in-service equipment in order to predict when maintenance should be performed. This approach results in cost savings over routine or time-based preventive maintenance (PM), because tasks are performed only when warranted.

The main goal of Predictive Maintenance is to allow convenient scheduling of corrective maintenance and to prevent unexpected equipment failures. The key is "the right information in the right time". By knowing which equipment needs maintenance, maintenance work can be better planned. What would have been unscheduled stops are transformed to shorter and fewer planned stops. Other potential advantages include increased equipment lifetime, increased plant safety, fewer accidents with negative impact on environment, and optimized spare parts handling.

We encourage our customers to follow a comprehensive approach for predictive maintenance projects, including: 

• Ultrasonic Compressed Air Leak Analysis: A Ultrasonic Compressed Air Leak Analysis includes identification (including tagging), leak cost report, repair verification, and employee involvement. Leaks are expensive. Statistics show that the average system wastes between 25 and 35% to leaks. A 3/8” leak at 100 psig, for example, may cost $31,200 per year. The higher the system pressure, the more air lost through leaks.

  A leak prevention program should be part of an overall program aimed at improving the performance of compressed air systems. Once the leaks are found and repaired, the system should be re-evaluated. 

  A good compressed air system leak repair program is very important in maintaining the efficiency, reliability, stability and cost effectiveness of any compressed air system.

• Certified Level 1 Infrared Thermographic Inspections: These inspections find hot spots caused by defects in connections and components of electrical equipment. Using this technology, problems can be corrected before a component fails, which could cause damage to the component, create safety hazards and result in productivity loss. Insurance companies are increasingly asking for electrical infrared inspections to be performed and items corrected before they cause damage to your personnel, equipment, and facility.

Our service covers all process steps, starting with the detection and early warning of process deviations and machine failures, through the planning of non-invasive testing and documentation.

GR Energy is also able to offer services to correct issues found in any predictive maintenance reports as well as provide ongoing comprehensive plant maintenance services.
