White Paper: Condition Based Maintenance for Supermarket Refrigeration Systems

Emerson Climate Technologies recently released a white paper titled “Condition Based Maintenance: Putting Predictive Maintenance Algorithms to Work to Optimize Asset Maintenance and Performance in Supermarket Refrigeration Systems.” In this paper, I introduce the concept of condition based maintenance (CBM), highlighting the benefits of this service for retailers, illustrating the savings in maintenance costs and energy consumption that can occur with the adoption of CBM.

Typical Equipment Failure Impact (Conventional PM or Run-to-Failure)

Typical Equipment Failure Impact (Conventional PM or Run-to-Failure)

CBM is basically what it says: performing maintenance based on the condition of the equipment being monitored, rather than on a preventative maintenance (PM) schedule or after a failure. Using CBM, retailers can expect to see typical equipment maintenance savings of 18-40 percent, compared to PM or run-to-failure strategies. The regular reporting function, combined with technical expertise to interpret it, provides actionable intelligence with significant ROI.

By utilizing run-time data analysis to optimize asset maintenance and equipment performance, CBM provides supermarket maintenance managers with a sustainable maintenance solution that offers visibility into the condition of their refrigeration systems.

Typical maintenance interventions from CBM could include:

  • Determining the source of a refrigerant slow leak and repairing it before further leakage or other system fault
  • Replacing worn compressor motor contactors  prior to a welded contactor condition and compressor failure
  • Determining the source of a compressor low or high superheat condition prior to damaging  the compressor
  • Correcting  a inconsistent phase-phase voltage in the compressor, protecting against damage from overheating

CBM also uses algorithms for refrigerant slow leak detection, enabling early detection and potential resolution, which can save refrigerant, equipment, product and overtime labor.

Emerson offers condition based maintenance as part of its ProAct™ Services portfolio, offering new value to retailers in the areas of maintenance and energy management, and in compliance for refrigerant management and food quality.

For more information on condition based maintenance, you can also read previous Climate Conversations blog posts, including an introduction to CBM and an overview of my 2013 Technology in Action Conference (TAC) presentation.

What maintenance strategies do you use? Does condition based maintenance offer a solution to your maintenance concerns?
