Learning how to choose a used generator for an industrial facility in dubai is a strategic financial decision for factory owners, metal fabrication workshops, logistics hubs, and cold storage depots across Dubai Industrial City, Al Quoz, and JAFZA. A properly selected pre-owned industrial generator provides reliable prime or emergency standby power at up to 50% lower capital cost than a brand-new unit.
Key Industrial Power Factors in Dubai
1. Motor Inrush and Inductive Electrical Loads
Manufacturing facilities operate heavy electric motors (air compressors, overhead cranes, conveyor lines, and industrial chillers) that draw 4 to 6 times their rated running current upon startup. When choosing a used generator, ensure the alternator features a high-grade Automatic Voltage Regulator (AVR) with auxiliary winding (PMG - Permanent Magnet Generator) excitation capable of supporting 300% short-circuit current for 10 seconds without collapsing.
2. Summer Ambient Derating (50°C High-Ambient Operation)
In peak Dubai summer, ambient temperatures inside industrial zones frequently reach 48°C to 50°C. Standard generators rated for temperate European climates suffer severe thermal throttling. Select a used generator equipped with a heavy-duty tropicalized desert radiator and size the unit so your peak continuous demand equals approximately 70% to 75% of the generator's prime kVA rating.
3. DEWA Interlocking and Grid Compliance
Under Dubai Electricity and Water Authority (DEWA) regulations, any standby generator connected to a facility with grid power must feature an approved 4-pole Automatic Transfer Switch (ATS) with mechanical and electrical interlocking to prevent back-feeding into the municipal utility grid.
Industrial Facility Sizing Matrix (Dubai)
| Industrial Facility Type | Primary Equipment | Recommended Capacity | Recommended Model |
|---|---|---|---|
| Carpentry & Joinery Workshop | Table saws, dust extraction blowers, spray booths | 150 kVA - 250 kVA | 250 kVA Perkins Silent |
| Metal Fabrication & Steel Structure Plant | MIG/TIG welding banks, plasma cutters, 10T crane | 400 kVA - 500 kVA | 500 kVA Cummins Heavy Duty |
| Food Processing & Cold Storage Warehouse | Blast freezers, cold room condensing units, packaging | 600 kVA - 800 kVA | 800 kVA Soundproof Unit |
| Heavy Chemical / Plastics Extrusion Factory | Extrusion heaters, water chillers, continuous lines | 1000 kVA - 1250 kVA | 1000 kVA Cummins Synchronized |
Selecting the Right Engine Brand for Dubai
For industrial facilities in Dubai, choose engines with extensive local parts distribution. Perkins (UK) and Cummins (USA) dominate the UAE industrial market. Sourcing replacement turbochargers, water pumps, sensors, and filters in Dubai takes hours rather than weeks, preventing costly production halts.
Integrating Temporary Power with Process Cooling
If your manufacturing facility also requires supplementary thermal control during peak summer, explore our integrated rental cooling chillers and modular packaged AC units.
Frequently Asked Questions
Can a used generator handle electronic CNC machines and PLCs?
Yes, provided the alternator features an Automatic Voltage Regulator (AVR) with Total Harmonic Distortion (THD) below 5%. Always verify power quality with a load test before connecting sensitive microprocessor controls.
What fuel tank capacity is recommended for industrial facilities in Dubai?
For continuous operation, pair your generator with an external double-walled 1,000 to 2,500-gallon bulk fuel tank with automatic fuel transfer pumps to ensure 48 to 72 hours of uninterrupted autonomy.
Does Rental Power UAE assist with civil pad and electrical installation?
Yes. Our turnkey engineering team provides complete site surveys, concrete foundation recommendations, cable routing, earthing pit testing, and final DEWA compliance testing.
