Undetected issues in your system's performance waste energy (and money), jeopardize your product, and could eventually result in a catastrophic failure. NRM arms you with the tools to stay ahead of them.
If your facility has redundant systems, or bare-bones temperature monitoring, you may not be aware of performance issues currently plaguing your refrigeration equipment. For example, the owners of this large cooler were unaware that one of the compressors was cycling 2000+ times per day since the second compressor unit met the load requirements. This undetected issue put their system at severe risk.
Here is a visual trend of that same refrigeration system's operation after the facility's staff were made aware of the short-cycling issue and the issue was resolved. Their refrigeration technician was called, and then diagnosed the diagnosing the issue as a plugged filter that was restricting refrigerant flow. This was causing the compressor to pump down and restart every 30 seconds.
In today's fast-paced business environment, it's not enough to simply be made aware that one of your space temperatures has gone out of range. Without context for better troubleshooting and diagnoses, the temperature issues will happen over and over again. In this university dining scenario, Remote Site Manager displays exactly when and where the compressor failed, which caused the temperatures of both the space and the evaporators to rise.
With Remote Site Manager, there's no need to "take someone's word for it" that a problem has been successfully corrected. This visual trend shows the problematic compressor back to normal within two days, thanks to the customer quickly calling their refrigeration technician, who discovered the system lost its refrigerant charge. The visual trends verify their work, improving the transparency of customer/contractor relations.
One of the most beloved features of the Remote Site Manager visual trends is how quickly you can assess whether your system is running optimally and efficiently. This visual trend, for example, shows a production freezer running its regular cycling as dictated by the energy-efficiency smart controls implemented by NRM.
Sometimes, the issue that causes your space temperatures to fall out of their desired range, and put your invaluable product at risk, are of a human nature and not a mechanical one. This visual trend shows the same production freezer later in the day, suffering from high temperatures due to the freezer's door being left open.
NRM's smart controls make for a perfect pair with Remote Site Manager. With this large cooler, multiple compressors operate under a lead/lag strategy with 3-hour cycles. Logging into the Remote Site Manager dashboard, the customer is able to track the performance of each unit, and across each zone.
Due to the dual cooling systems in this cooler, temperature was maintained despite one of the compressors beginning to fail. Of course, replacing a blown compressor is far more expensive than repairing one, and so when the customer was alerted that one of the systems was short cycling excessively (an issue they would not have been notified of with basic temperature monitoring), they were able to get the unit repaired before anything drastic occurred.
