Exploring the Real-World Value of Compressor Electronics Data

Nothing demonstrates the value of new technologies better than real-world examples. While preparing for our recent Making Sense webinar on improving operational visibility, I was struck by countless customer testimonies that demonstrate where they saved thousands of dollars through the analysis of data available from CoreSense™ technology. I was excited to include a few examples in the webinar that moved the discussion from theoretical concepts to tangible applications.

First, there was the supermarket that responded to a high case temperature alarm and through troubleshooting was able to identify the root cause as a bad contactor. The data identified the problem early and through remote troubleshooting focused the efforts on the failing contactor. Without compressor electronics the issue would have resulted in a compressor failure. Therefore, the customer simply replaced the faulty contactor, avoided compressor failure and saved approximately $6,000.

Next, a contractor for a convenience store with a walk-in cooler received an alarm that a compressor had overheated. On further analysis of the data, they discovered that a low-pressure, cut-off fault had caused a harmful system loop of cooling, overheating, protector tripping and resetting. With CoreSense technology, the contractor was notified of the problem and arrived on-site to finish troubleshooting. By preventing compressor failure, the store saved $6,000 in replacement costs.

And when a compressor stopped running in a butcher’s walk-in cooler because the defrost timer had frozen, CoreSense warned the contractor of the system trip and then sent an alarm four hours later when the control circuit had not reset. The notifications prompted the contractor to fix the issue before $10,000 of the butcher’s product had spoiled.

These examples demonstrate how a compressor can be effectively used as a sensor. Facilities managers and contractors can use compressor electronics to not only receive notifications of failures before they happen, but also rely on the built-in diagnostics to initiate shut-down sequences when needed. They’re also able to perform proactive maintenance and enhance overall performance reliability. On an enterprise level, compressor data can be used to monitor store-level data to identify top issues, evaluate best- and worst-performing stores, and prioritize equipment and maintenance efforts.

If you were unable to attend the webinar and would like to learn more about compressor electronics data, you may view our archived webinars on our website. And, keep an eye out for our next webinar where we’re Making Sense of the latest trends that are shaping the refrigeration industry at
