Map Your Risk Profile
List every cold room, undercounter fridge, and prep cooler, then note which Eskom block each circuit belongs to. Facilities spread across the CBD, Claremont, and the Northern Suburbs often fall under different schedules, so synchronising production and deliveries around outage windows prevents panic-stockpiling that strains refrigeration capacity.
Invest in Smart Monitoring
Install Wi-Fi or GSM temperature sensors that log readings every five minutes and send SMS alerts once a cabinet exceeds 5 °C. Choose devices with onboard memory to keep data even when routers power down. This proof protects you during insurance claims and health inspections.
Stage-by-Stage Backup Strategy
- Stage 1–2: A pure sine-wave UPS can bridge short cuts for POS fridges and beverage coolers.
- Stage 3–4: Petrol or diesel generators sized at 1.5× the total compressor load keep cold rooms stable. Wire them through an automatic transfer switch to avoid manual mistakes.
- Stage 5+: Consider a hybrid solar-battery system with demand management so that only mission-critical fridges stay on, while less sensitive stock moves to ice-packed containers.
Operational Best Practices
Schedule defrost cycles for early mornings before outages start. During cuts, keep doors sealed and station a supervisor to log every access. Pre-chill blast freezers two hours beforehand so the pull-down effect continues through the blackout. Train staff to wrap shelves with thermal curtains to reduce convection losses.
Maintenance That Matters
Load-shedding subjects compressors to repeated restarts. Ask your refrigeration partner to inspect contactors, capacitor values, and oil levels quarterly. Fit surge protection on every distribution board feeding cold rooms to prevent motherboard failures.
