Choosing a Backup Generator for a Water Refill, Milk ATM or Dairy Business
- Add up the running power of everything that must stay on
- Allow extra for motors starting (pumps, chillers, compressors)
- Diesel suits long running hours; petrol suits short backup
- Automatic transfer switch = switches over by itself

An automatic transfer switch (ATS) starts using the generator when mains power fails and switches back when it returns, so a milk chiller or refill station keeps running without anyone present (with a generator that supports auto-start).
How to Size a Generator
- List what must keep working: chiller, milk ATM, RO plant, pumps, lights, payment system.
- Add up their running power (on each nameplate, in watts or kW).
- Add extra for motor starting: pumps and compressors draw several times their running power for a moment.
- Choose a generator above that total, and do not run it at full load for long periods.
Send us the list of equipment and we will recommend a size.
Petrol or Diesel Generator?
| Petrol | Diesel | |
|---|---|---|
| Best for | Short outages, small loads | Long running hours, bigger loads |
| Purchase price | Lower | Higher |
Can You Run a Generator Overnight or Every Day?
Generators can run for long periods if they are sized correctly, kept serviced (oil, filters) and have enough fuel and ventilation. Follow the service schedule in the manual.
Generator Safety
- Run generators outdoors only: exhaust contains carbon monoxide, which can kill.
- Keep them dry and away from doors and windows.
- Connect through a proper changeover or transfer switch fitted by an electrician, never by back-feeding a socket.
