250 kVA Generator Rental in UAE | Silent Diesel Generator Hire Dubai
A 250 kVA unit is the entry point into the UAE’s mid-tier commercial and industrial rental class, carrying enough torque reserve to start a second sizeable motor shortly after the first without a sequential soft-start controller. It is the most commonly specified capacity for multi-storey building shells and single-plant industrial units where the load schedule exceeds what a 200 kVA genset can absorb on inrush.
Power Output: 250 kVA Prime (200 kW) and 275 kVA Standby (220 kW) at 0.8 PF.
Engine Platform: Cummins 6CTAA8.3-G3, a 6-cylinder, 8.3-litre turbocharged and charge-air-cooled block tuned for a higher governor response than the 200 kVA variant.
Acoustic Canopy: 72-76 dB(A) at 7m, with a finned extended-core radiator and belt-driven pusher fan rated for continuous 50°C+ ambient running.
Turnkey Support: 24/7 mobile engineer dispatch, flatbed trailer transport, and on-site commissioning across all seven Emirates.
250 kVA GENERATOR TECHNICAL SPECIFICATIONS
This size class retains the 8.3-litre Cummins displacement used at 200 kVA but runs a higher-output alternator and uprated governor calibration, which is why the two capacities share an engine family but not a fuel curve. Below is the full build specification confirmed on your test certificate at delivery.
| Parameter | Specification |
|---|---|
| Prime Power Rating | 250 kVA / 200 kW @ 0.8 PF |
| Standby Power Rating | 275 kVA / 220 kW @ 0.8 PF |
| Continuous Operating Power (COP) | 227 kVA / 182 kW |
| Engine Model & Displacement | Cummins 6CTAA8.3-G3, 6-Cylinder In-line, 8.3L, Turbocharged & Charge Air Cooled |
| Alternator Model | Stamford UCI274J or Leroy-Somer LSA 44.3 VS2, Brushless, Class H Insulation, IP23 |
| Voltage / Phase / Frequency | 400V / 230V, 3-Phase + Neutral, 50 Hz |
| Noise Level @ 7m | 72-76 dB(A) |
| Base Fuel Tank Capacity | 450-500 Litres, approx. 9-10 hours at 75% Prime Load |
| Control Panel | Deep Sea DSE 8610 MKII (standard, sync/paralleling capable) |
| Main Circuit Breaker | 3-Pole / 4-Pole Motorized MCCB, 400A frame, adjustable 0.4-1x In overload |
| Dimensions (L x W x H) | 4,100 mm x 1,400 mm x 2,150 mm |
| Operating Weight | Dry: approx. 2,950 kg / Wet: approx. 3,300 kg |
| Rigging & Handling | Central lifting eye rated to wet weight, forklift pockets, twin-axle trailer chassis standard |
ESTIMATED FUEL CONSUMPTION MATRIX
The uprated governor on the G3 block trims specific fuel consumption at 75% load compared to the 200 kVA G2 variant, which is the load band we recommend you plan contract fuel budgets around.
| Load Level | Output (kW) | Fuel Burn (L/hr) |
|---|---|---|
| 25% Load | 50 kW | 14.0 L/hr |
| 50% Load | 100 kW | 26.5 L/hr |
| 75% Load (Optimal Prime) | 150 kW | 38.0 L/hr |
| 100% Full Load | 200 kW | 50.5 L/hr |
Note: Peak summer ambient above 48°C can derate continuous output by 3-5%, so for multi-day hires we schedule mobile bowser top-ups against logged load data rather than a fixed delivery interval.
TYPICAL APPLICATIONS FOR 250 kVA GENERATORS IN UAE
This capacity is sized for sites running two concurrent significant motor loads, or one large motor plus a full commercial balance-of-plant, rather than a single dominant machine.
Primary Construction & Industrial Equipment: A tower crane hoist motor running alongside a concrete pump or batching plant mixer, plus 3-4 submersible dewatering pumps and a multi-cabin site office complex.
Commercial Facility & Backup Scenarios: Mid-rise residential towers (G+15 to G+25 common areas), hotel back-of-house and kitchen loads, and district cooling plant room backup during planned maintenance.
HVAC & Temporary Cooling Integration: Matched to one 90-100 ton air-cooled package chiller, or a 70-80 ton chiller running alongside separate lighting and small power circuits.
Specialized Sector Application: Larger exhibition halls at DWTC requiring simultaneous AV, catering, and HVAC loads, and two-train refinery turnaround instrumentation packages.
Grid Outage & Emergency Support: Sized for a feeder-level DEWA/ADDC trip affecting a full mid-rise building or small industrial unit, where load exceeds what a 200 kVA set can carry without running near its ceiling.
WHAT IS INCLUDED IN OUR 250 kVA RENTAL PACKAGE?
Because this class frequently runs two concurrent motor starts, we confirm cable sizing and ATS rating against your sequencing plan, not just total connected load.
Load-Bank Testing: 100% resistive load-bank test verification report issued and dated before dispatch.
Power Cabling: 4-core 150 mm² to 185 mm² flexible copper, sized per run length against a maximum 5% voltage drop at full load.
Switchgear & ATS: Optional 315A-400A ATS panel, sized to handle sequential motor reconnection on mains restoration.
Distribution Boards: Weatherproof MDB fitted with IP67 CEE sockets in 32A, 63A, and 125A combinations.
Technical Service: 24/7 mobile engineer coverage, with priority response calibrated for parallel-operation fault conditions.
RAPID DELIVERY COVERAGE ACROSS THE UAE
At 2.95-3.3 tonnes wet weight, this unit ships on a twin-axle trailer and generally only needs crane offloading where ground access is restricted.
Dubai & Sharjah: 2-Hour rapid emergency site delivery and connection.
Abu Dhabi & ICAD/Mussafah: Same-day delivery, electrical connection, and commissioning.
Northern Emirates (Ajman, RAK, UAQ, Fujairah): Scheduled turnkey transport with mobile crane offloading where site access requires elevated placement.
Frequently Asked Questions
Yes, this generator has enough reserve power to handle a second large machine starting up shortly after the first, without cutting out or tripping.
Yes, we fit an automatic switch that brings your equipment back onto mains power in stages rather than all at once, which protects both the generator and your building's electrical system.
Yes, two 250 kVA units can be connected to work together, either to combine their power for a bigger job or so one takes over automatically if the other needs servicing.
Yes, for longer distances we use a thicker cable or run two cables side by side to make sure you don't lose power along the way, and we check this for your specific site before delivery.
