Compressor failure prediction and predictive maintenance for supermarket racks.
A failed rack compressor means a crane, a rush order, overtime and sometimes lost product. Most failures develop over weeks, between service visits, when nobody is looking at the data. KalderIQ looks at it continuously.
Why compressors fail between visits.
Compressors are usually replaced after something upstream has been wrong for a while: an operating condition drifting out of range, an intermittent control problem, a system running outside its design envelope. A technician on a scheduled visit sees one moment. The damage happens in the weeks between.
Warning signs technicians look for.
Compressor failures in supermarket racks usually have a cause that shows up before the failure itself. Technicians look for patterns such as short cycling, liquid returning to the compressor, discharge temperatures running high, repeated safety trips and oil problems. Each one is easy to miss on a single visit and obvious in weeks of data.
How KalderIQ protects compressors.
KalderIQ compares each compressor’s operating data with its expected envelope, continuously. When a compressor starts showing distress, the finding is ranked and sent to your team with the data behind it. Your technician makes a routine correction instead of a replacement.
Predictive maintenance, not more maintenance.
Predictive maintenance for a refrigeration rack does not mean more service visits. It means sending a technician when the data says a compressor is heading for trouble, with the reason attached, instead of waiting for the failure or visiting on a fixed schedule. The work is usually a routine correction, done at a planned time.
Eleven failures, then none.
A multi-site grocery operation replaced eleven compressors between July 2023 and June 2025. KalderIQ compressor-protection monitoring started across the same sites in June 2025. Technicians acted on the findings with routine service corrections, and the sites reported no compressor replacements in the following year.
At about C$21,000 per replacement, including crane, labor and materials, the previous rate of 5.5 replacements a year was costing roughly C$115,000 annually.

Common questions
What is predictive maintenance for supermarket refrigeration?
Using continuous operating data from the refrigeration controllers to send a technician before a component fails, instead of after a failure or on a fixed schedule. For racks, the biggest payoff is usually avoiding compressor replacements.
Can supermarket compressor failures be predicted?
Many can be anticipated. Compressor failures often follow weeks of abnormal operation that shows up in controller data. KalderIQ flags that distress so a technician can correct the cause before the compressor fails.
Does compressor protection need new sensors?
KalderIQ works from the data your connected refrigeration controllers already collect. We confirm what data is available at each store during setup.
Is zero compressor failures guaranteed?
No. The eleven-to-zero result is one operation’s first year of monitoring. Unrelated failures can still happen, but a technician acting on early findings removes many of the common causes.
