If you are comparing a generator set factory for a project in the United Arab Emirates, start with the duty, required prime or standby power, and the site’s confirmed frequency and voltage—not just the largest number on a product sheet. The listed diesel generator set range here covers 20 kW to 3,000 kW, with 50 Hz models and different voltage ratings. Use those details as a shortlist, then confirm the exact electrical, environmental, installation, and commercial requirements for your project before requesting a quotation.

What to verify when comparing a generator set factory

A generator set is a system selection, not only an engine choice. Procurement teams, distributors, EPC contractors, and facility engineers should compare the complete rating and configuration against the intended application. Ask for a written offer that identifies the model, prime power, standby power, frequency, voltage, engine and alternator models, and any included options. Confirm whether each item is part of the quoted scope rather than assuming it is included.

The product examples below show a range of 50 Hz diesel gensets. Their power ratings, voltage, engine models, and other listed specifications are model-specific; they should not be treated as interchangeable configurations.

• KC-DC20G: 20 kW prime power and 22 kW standby power; 50 Hz; 400/230 V; 4B3.9-G1 diesel engine; KCI-20 alternator. Listed emission classification: China Stage II.
• KC-W64Y88: 64 kW prime power and 70 kW standby power; 50 Hz; 400/230 V; WP4.1D80E200 diesel engine; KCI-64 alternator. Listed emission classification: China Stage II.
• KC-P160: 160 kW prime power and 176 kW standby power; 50 Hz; 230/400 V; 1106A-70TAG4 diesel engine; KCI-160 alternator. No emission classification is stated in the available product details.
• KCV-282GF: 282 kW prime power and 310 kW standby power; 50 Hz; 400/230 V; TAD1342GE-B diesel engine; KCI-282 alternator. Listed emission classification: China Stage II.
• KC-450: 450 kW prime power and 500 kW standby power; 50 Hz; 400/230 V; KCV550 diesel engine; KCI-450 alternator. Listed emission classification: China Stage II.
• KC-C650: 650 kW prime power and 700 kW standby power; 50 Hz; 400/230 V; KTA38-G2E diesel engine; KCI-650 alternator. Listed emission classification: China Stage III.
• KC-S1118: 1,118 kW prime power and 1,229.8 kW standby power; 50 Hz; 400/230 V; 6WTAA35-G313 diesel engine; KCI-1118 alternator. Listed emission classification: China Stage III.
• KC-YC3000: 3,000 kW prime power and 3,300 kW standby power; 50 Hz; 380/220 V; YC16VC4900-D30 diesel engine; KCI-3000 alternator. Listed emission classification: China Stage III.

These are useful reference points for matching project scale to available ratings. The figures do not establish suitability for a particular facility, and the emission classifications shown should not be assumed to satisfy any specific UAE project requirement. Confirm the exact proposed configuration and applicable project criteria with the supplier and relevant project stakeholders.

Size the genset for the real load

Prepare a load schedule before choosing a model. Record the equipment to be supplied, its running demand, the loads that may start together, and any planned future additions. Separate essential loads from loads that can be shed during an outage. Ask the project electrical engineer or genset supplier to review the load sequence and the proposed operating conditions; do not select a rating solely by adding nameplate values without considering how the loads operate.

The product list provides examples from 20 kW through 3,000 kW, but it does not provide a sizing calculation for a specific facility. For a first inquiry, share the estimated total demand, largest motor or other significant starting load, expected load steps, and whether the unit will support one building, a production area, or a larger site. These details allow the supplier to assess which rating needs further review.

There are anonymous factory-logistics project examples at 250 kW and 600 kW, including a 600 kW example identified with a Yuchai YC6TD1000-D31. They provide context for equipment used in that industry and power range, not a guarantee of performance or a recommendation for another site. Match the rating to your own load schedule and operating conditions.

Confirm prime power or standby power

The listed models provide separate prime and standby ratings. In your request for quotation, state which rating is required for the intended duty and ask the supplier to confirm the applicable rating for the proposed operating pattern. Do not treat the higher standby figure as the routine-duty rating without written confirmation that it suits the planned use.

For example, the KC-450 is listed at 450 kW prime power and 500 kW standby power; the KC-C650 is listed at 650 kW prime power and 700 kW standby power. Those differences matter when comparing offers. Request the rating basis, expected operating schedule, and any conditions or limitations that the supplier uses for its rating proposal. If the project requires continuous or extended operation, describe that requirement clearly rather than relying on a generic “backup generator” description.

Match frequency and voltage to the project

The listed product examples are rated at 50 Hz. Voltage is not identical across the range: several models are specified at 400/230 V, the KC-P160 at 230/400 V, and the KC-YC3000 at 380/220 V. Confirm the exact required frequency, voltage, phase arrangement, and connection details for your project before comparing models or placing an order. Do not assume that a 50 Hz product is suitable for a project with different electrical requirements, or that two voltage notations can be substituted without engineering confirmation.

For UAE procurement, provide the project’s confirmed electrical requirements and ask the supplier to state them on the technical offer. If a project specification, EPC standard, or end-user document calls for particular electrical or site conditions, send the relevant requirements for review. The available product details do not confirm 60 Hz models, alternative voltage configurations, or compliance with project-specific requirements.

Review installation and operating details before award

Compare the available physical and electrical data with the project’s site plan. For example, the KC-DC20G is listed at 1,700 × 750 × 1,100 mm and 750 kg, while the KC-C650 is listed at 4,300 × 1,700 × 2,450 mm and 7,500 kg. Check access routes, handling arrangements, foundation or support requirements, ventilation, exhaust routing, and maintenance clearances with the responsible project team. These are site-planning checks, not installation details specified by the product figures above.

Several models list a brushless three-phase AC synchronous alternator, AVR (automatic voltage regulator), IP23 protection class, H insulation class, and self-excited excitation. Confirm these details against the specific model proposed in the quotation. The listed product data also gives noise as 102 dB at LP7M for the examples; if noise is a project constraint, request clarification of the measurement basis and ask whether a suitable configuration is available. Do not assume a soundproof canopy is included, as that is not specified in the product details here.

Ask separately about items that affect project scope and total cost: control and transfer arrangements, fuel-tank configuration, enclosure, accessories, commissioning, documentation, maintenance support, warranty, delivery schedule, and payment terms. These details are not stated in the product specifications above, so they should be confirmed in writing rather than inferred from a model number or power rating.

Send a complete inquiry for a useful quotation

A clear inquiry helps the supplier assess the right model and expose any gaps before procurement approval. Include:

• Required prime and standby power, with the intended duty and operating schedule.
• Confirmed frequency, voltage, phase, and connection requirements.
• Load schedule, major starting loads, and any planned capacity additions.
• Installation location, access or space constraints, and relevant site conditions.
• Required engine or alternator preferences, if the project specifies them.
• Applicable project documents and any emission, noise, electrical, or inspection criteria that the offer must address.
• Requested scope, including any required enclosure, fuel arrangement, controls, documentation, installation, or after-sales support.
• Target procurement milestones and the destination details needed for a commercial offer.

For a UAE project, ask the supplier to identify any assumptions or exclusions in the offer and to confirm which requirements remain subject to project or local review. Request a model-specific technical proposal that states the rating basis, frequency, voltage, and included equipment. Then compare offers on the same duty and scope—not just on headline kW.

To begin, send your load schedule and project electrical requirements with a request for a model recommendation and quotation. Ask the supplier to confirm technical fit and list any missing information needed to finalize the proposal.

FAQ

What can cause black smoke from a generator set?

Black smoke indicates incomplete combustion. Possible causes include a clogged air filter restricting intake, excessive fuel injection, poor injector atomization, a sudden excessive load, or poor-quality diesel. Clean the air filter, use suitable diesel, inspect the injection system, and avoid prolonged operation under excessive load.

How can I tell whether an automatic shutdown is a protection trip or hardware damage?

Check the controller’s stored fault codes first. If overspeed, high temperature, or low oil pressure protection has activated, reset the protection manually after addressing the cause. If there is no fault code, check the battery and fuel system.

Why might a brushless generator have no voltage after being stopped for a period?

The alternator may have lost residual magnetism. Flashing can restore it. Windings in a damp environment can lose magnetism more readily, so keep the generator room dry.

How often should a generator set receive routine maintenance?

The first service for a new unit is at 50 hours, including changing the engine oil, oil filter, and diesel filter. Routine service is every 200–250 hours and includes changing the oil and three filters; checking the belt, coolant, battery, and piping; tightening fasteners; and cleaning the air filter and radiator. Carry out a full-unit inspection annually.

What should I check when a generator set has high coolant temperature or shuts down on a high-temperature alarm?

Check the coolant level, radiator blockage, fan speed, thermostat, and water-pump operation. Clean the radiator cooling system and address blockages or restricted coolant circulation.
