Monitors each refrigerated case's defrost cycles from the controller — whether a cycle starts on schedule, terminates on its configured condition within its expected duration, and lets the case recover. Catches a missed, run-long, or unterminated defrost before it ices the coil and pushes the case out of band.
Impact: Catches a missed or failed defrost upstream of the temperature excursion it would cause — turning a would-be product-loss event on the case into a scoped controller or vendor action while the product is still good.
What it solves: A refrigerated case defrosts on a commissioned schedule, and a defrost that is missed, runs long, or fails to terminate is one of the most common controllable causes of a temperature excursion that is not a hardware fault — it ices the coil or holds the case warm past its recovery window. Keedian reads the case controller for the defrost cycle itself: it confirms a cycle started on schedule, terminated on its configured condition inside its expected duration, and that the case settled back into band after the suppression window. A Delay-After-Defrost parameter is treated as an alarm-suppression window, never as proof a cycle ran. Where the controller or added instrumentation exposes actual defrost start, end, duration, and case temperature, the add-on surfaces a missed, over-long, or unterminated defrost — and the abnormal post-defrost recovery it correlates to Temperature Recovery — as managed alarms routed to the customer's refrigeration vendor with a recommended action. Applies only where that defrost evidence exists.
These are the operational metrics this add-on monitors and alarms on. Keedian surfaces them and, where the contract includes managed service, triages them; acting on the physical asset stays with you and your vendors.
The core metrics are summarized below. Full methodology, thresholds, diagnosis steps, and escalation criteria are in the Metrics Catalog.
Each metric includes definition, detection logic, diagnosis steps, recommended actions, escalation criteria, and prevention controls. Thresholds are reference values to be calibrated per client.
View Metrics Catalog →Defrost cycles are confirmed to start, terminate, and recover as commissioned per case, and a missed, over-long, or unterminated defrost is caught before it becomes a temperature excursion. Expected (pending validation).
The defrost alarms run as managed workflows on the same accountability as the rest of the contract — surfaced, triaged, and routed to the customer's refrigeration vendor with a recommended action and the correlated case-temperature evidence.
