Predictive Maintenance for Grocery

Find refrigeration problems days before they become after hours callouts.

Bueno’s Predictive Maintenance flags the equipment that needs attention before it fails, across your refrigeration and HVAC network, using the data your controllers already produce. It spots high temperature alarms days ahead, shows condenser decline and compressor floodback early, and pools the flagged jobs into one planned visit instead of several separate truck rolls. It connects to any controller or building management system (BMS) from any manufacturer, with no new sensors, and your technician makes every repair.

Instead of reacting to failures, or servicing every unit on a fixed calendar whether it needs it or not, your team works from the condition of the equipment, with jobs ranked by urgency and cost.

Bueno is the most advanced predictive maintenance platform in grocery. It moves your team from emergency dispatches to planned work, with fewer callouts, longer equipment life and lower maintenance and energy costs.

Key facts about Predictive Maintenance

Looking for leaks or energy savings? Refrigerant Leak Detection and Energy Optimisation run on the same data model. See the three solutions. Jump to the solutions
  • Predictive Maintenance is one of three Bueno grocery solutions, with Refrigerant Leak Detection and Energy Optimisation. All three run on one data model.
  • It finds equipment problems before they cause a failure, using data your controllers already produce. No new sensors are required.
  • For example, case icing is spotted 5 to 7 days before the high temperature alarm, 95% accurate at Woolworths, so the fix is a planned daytime visit, not an after hours callout.
  • It also flags condensers running outside their expected performance, and compressor floodback, with the case causing it identified.
  • Maintenance is triggered by what the equipment is actually doing, not by a fixed calendar. Flagged jobs are pooled into one planned visit.
  • Bueno is agnostic. It connects to any controller or BMS from any manufacturer. Bueno finds, ranks and recommends, and your technician makes every repair. It never controls your equipment.
  • At Woolworths, Bueno predicts about 1,800 case icing events a year and has cut ice-up related callouts by 22%.
OVERVIEW

What is predictive maintenance in grocery refrigeration?

Predictive maintenance finds equipment problems before they cause a failure, by reading the operating data of the equipment itself. Bueno analyses the data your rack, case and HVAC controllers already produce every 5 minutes, and flags the trends that come before a fault, such as case temperature creeping up as ice builds on a coil.

That changes how work gets done. Instead of waiting for equipment to fail, or servicing every unit on a fixed calendar, your team works from the condition of the equipment, and Bueno pools the flagged jobs for a site into one planned visit.

KEY TERMS

Key terms in predictive maintenance

Predictive maintenance

Fixing equipment before it fails, because operating data shows it is heading toward a fault.

Condition based maintenance

Servicing equipment when its actual condition calls for it, not on a fixed calendar.

Case icing

Ice building on the coil of a display case, which pushes case temperature up between defrosts until it triggers a high temperature alarm.

Compressor floodback

Liquid refrigerant returning to the compressor, which can shorten compressor life.

WHAT BUENO PREDICTS

What does Bueno predict in grocery refrigeration and HVAC?

Bueno predicts the faults behind most after hours callouts and flags them early enough to plan the fix.

High temperature alarms, solved early

Up to 50% of refrigeration service calls start as a high temperature alarm. Bueno predicts these 5 to 7 days out, 95% accurate at Woolworths, so the fix is planned, not an after hours callout.

Condenser health, on data not a calendar

Bueno flags condensers running outside their expected performance envelope, so coil cleans are scheduled from actual degradation, not a fixed calendar interval.

Compressor floodback, with root cause

Bueno catches intermittent floodback earlier to maximise compressor life, and tells you which case is causing the issue, so your technician saves time on the callout.

Condition based, not calendar based

Maintenance is triggered by what the equipment is actually doing. Service visits are scheduled from real performance data, not a fixed timetable that checks everything regardless of need.

One platform across refrigeration, HVAC and energy

Bueno pulls refrigeration, HVAC and energy performance together into a single platform across your portfolio, so every store, and the network as a whole, is visible from one place.

EXAMPLE: CASE ICING

What does a Bueno prediction look like in practice?

Case icing is one example of the faults Bueno predicts. Bueno spots it by tracking how case temperature creeps up between defrosts as ice builds on the coil, and flags the trend 5 to 7 days before the high temperature alarm, which leaves about 6 days to plan the fix.

  • Case temperature creeps up between defrosts as ice builds on the coil.
  • Bueno spots the trend 5 to 7 days before the high temperature alarm, 95% accurate at Woolworths.
  • The fix becomes a planned daytime visit, not an after hours emergency.
  • At Woolworths, about 1,800 icing events are predicted a year, with 22% fewer ice-up callouts.

COMPARE

How does predictive maintenance compare with reactive and scheduled maintenance?

Predictive maintenance acts before a failure and only where it is needed, while reactive maintenance waits for the failure and scheduled maintenance visits every unit on the calendar.

WHY NOW

Why does grocery maintenance need to change now?

Grocery maintenance needs to change now because labour market constraints are increasing, budgets are under pressure and planned preventive maintenance models are 40 years old.

Technician capacity

Constraints in the labour market are increasing. Every wasted or after hours callout uses up scarce capacity.

The maintenance model

Heat waves, water shortages and cost increases are putting pressure on maintenance budgets. Planned preventive maintenance (PPM) models are 40 years old.

Alarm driven callouts

Up to 50% of refrigeration service calls start as a high temperature alarm. Predicting those alarms turns an emergency into a planned visit.

Energy cost

Refrigeration is often a store’s largest load. Small drift, repeated across hundreds of stores, becomes a big number.

AGNOSTIC BY DESIGN

How does Bueno connect to refrigeration and HVAC controllers?

Predictive Maintenance reads the rack controllers, case controllers and HVAC BMS you already have, from any manufacturer, through a gateway, API or proprietary protocols, including Connect+. No new sensors are needed.

That same data model powers all three Bueno grocery solutions: Refrigerant Leak Detection, Predictive Maintenance and Energy Optimisation. Select a solution in the diagram to see which connections it reads and what it delivers.

HOW IT WORKS

How does a flagged fault become a planned visit?

Bueno turns a flagged fault into a planned visit in a short loop that takes controller data to a finished repair, and gets smarter each time.

1

Connect

Existing controllers, any brand, through a gateway, API or proprietary protocols, including Connect+.

2

Detect

300+ engineering rules and machine learning models run on 5 minute data.

3

Prioritise

AI ranks findings by cost and urgency and writes the work order in plain language.

4

Act

One visit fixes several issues. Your technician makes the repair, and technician feedback enhances the rules.
The loop closes, and the rules improve, with every technician’s feedback.

One visit, multiple fixes

When a predictive alert brings a technician to site, Bueno surfaces every other flagged issue at that location too. The real jobs are pooled into one visit instead of three separate truck rolls.
