How to Choose a Small Diesel Generator for Factory Use
Start from the real load, not the nameplate
List every machine you must keep running during an outage, then add their running power together.
Add 20%-30% margin for future expansion and inrush current.
Motors and compressors draw 3-5 times their rated current at start, so the generator must be sized for the worst starting case.
Match voltage, frequency and phase to your distribution
Most industrial sites in Africa use 380V/400V three-phase 50Hz; small shops often need 220V single-phase.
Our small diesel generator sets can be configured for 110V / 220V / 380V and 50Hz or 60Hz before shipment.
Decide between silent type and open frame type
Silent type: 70-75 dB(A) at 7m, suitable for residential areas, hospitals and hotels.
Open frame type: lower price, easier maintenance access, better for construction sites and workshops.
Check fuel type, tank capacity and running hours
All our diesel generator sets run on 0# or -10# light diesel oil.
A 15 L tank gives about 13-14 hours of continuous running at rated load.
Ask for a quotation with the full configuration
Tell us the required power, voltage, frequency, phase and application, and we will reply with price, datasheet and delivery time.
