Power Guide
A site-ready power guide for South African chillers, packing areas, and protein handling spaces.
How Power Guide applies in cold-chain spaces
The Power Guide page covers the power requirements around chillers, packing areas and protein handling spaces. It helps sites check what is needed before equipment is placed into a cold-chain workflow. For South African operations, that planning matters when receiving and storage cannot afford avoidable interruptions.
Use the Power Guide before a chiller, vacuum sealer, scale bench, or packing table is moved into place. It records what supply is available on site, where backup power starts and stops, and which points feed the cold room during load-shedding. For South African protein rooms, that check matters most where receiving is tight and product cannot sit warm while circuits are traced.
Photograph the DB board, plug points, isolators, and each refrigeration connection as you complete the guide. Include the time of day, who was on site, and any trip, voltage drop, or restart issue the team has seen before. Those details help a butcher shop, hotel prep area, or export kitchen map risk around handover and daily use.
Cold-room power points to capture
A completed Power Guide should show where primary supply enters the work area, what backup covers, and which equipment shares the same circuit. Note socket type, breaker size if known, cable route, and whether the space is wash-down, humid, or exposed to door-open traffic. That gives operations, maintenance, and install teams one working record instead of verbal guesses.
Pair the Power Guide with photos of the chiller entrance, condenser area, and packing bench before any equipment shift is approved. If there has been product loss after a cut, record what failed first and how long temperatures were affected.
- Backup source listed and photographed
- Cold room circuits identified clearly
- Failure history logged by area
South African cold-chain pressure points
Sites around Johannesburg, Durban, and Cape Town do not face the same operating conditions. Highveld storms, coastal moisture, and mixed-age electrical rooms all affect how chillers restart and how safely protein can be handled after an outage. The guide captures what the room can support, not what a plan drawing once suggested.
Older butcheries often have added plugs and split feeds that were never marked for refrigeration use. Hotel back-of-house areas may share supply with other heavy kitchen loads, while export kitchens need tighter control around uninterrupted cold storage. Record generator changeover time, alarm coverage, and any periods when doors stay open during receiving.

What to record on site
Use the Power Guide to note backup power, cold room supply, and refrigeration points, with photos, timing, and any failures already experienced on site.
List each powered unit in the handling space, from chiller evaporators to label printers if they affect dispatch. Add photos, outage timing, and any temporary workarounds staff use during Eskom interruptions. Keep the sheet with the equipment file so future service visits start from the actual room setup.
