A Chongqing builder of diesel and gas generator sets for export
Chongqing Dapu Power Equipment Co., Ltd. assembles, tests and exports diesel generator sets from 20 kW to 2000 kW and gas generator sets from 100 kW to 2000 kW. We supply distributors, contractors and project integrators who need a correctly sized set, a documented build and a supplier who answers technical questions quickly.
From engine selection to the packed container.
We work with diesel engines from Cummins and Dongfeng Cummins, Volvo Penta, Yuchai, Perkins, Weichai, Shangchai, Doosan, Deutz and MTU, and with gas engines from Cummins, MWM, Deutz, MAN, Weichai and Yuchai — matched with brushless alternators and control systems chosen for the application rather than by habit.
Our scope covers the complete build: base frame and canopy fabrication, control panel wiring, fuel and gas train assembly, load testing and export packing. Because assembly happens under our own roof, dimensions, tank capacity, gas train layout, voltage and control functions can be adapted to a specific project instead of shipping only catalogue units.
- Open-frame, silent, weatherproof, trailer, vehicle and container builds
- Diesel from 20 kW to 2000 kW, gas from 100 kW to 2000 kW
- 50 Hz and 60 Hz, 220–480 V, plus 6.3 kV and 10.5 kV high voltage
- Automatic, AMF, paralleling and grid-parallel control systems
- CHP heat recovery packages for gas sets
- Export packing and documentation prepared for customs and commissioning
Checked at every stage, not only at the end.
Production follows documented inspection from incoming material to the load test, so problems are found on our floor rather than on your site.
From our floor to your commissioning.
Each set leaves Chongqing packed for sea freight, with the test report, wiring diagram and English operation manual inside the container.
Ask about deliverySupport that continues after the container leaves.
Most of our customers are repeat buyers. That is not an accident: it comes from answering questions, supplying parts and standing behind the equipment.
Technical advice
Selection assistance, load calculations, gas analysis review and outline drawings before you commit to an order.
Commissioning help
Installation guidance, wiring documentation, gas train checks and start-up support, by remote assistance or on site.
Spare parts
Filters, sensors, control modules, alternators, ignition components and gasket kits, shipped with the set or after it.
Response commitments
Enquiries answered within one working day, technical questions resolved within three, and a fault diagnosis route agreed at order stage.
Answers before you send an enquiry.
What is the minimum order quantity?
One set. We regularly ship single units to end users and small orders to distributors. For dealers we can also discuss sample pricing and long-term cooperation terms.
What is the lead time for a standard set?
Standard ratings with a well-stocked engine normally ship within 15 to 25 working days after the deposit is received. Custom canopies, paralleling systems and high voltage units take longer. The confirmed date is written into the order.
Which voltages and frequencies can you build?
50 Hz and 60 Hz, with output voltages from 220 V to 480 V for standard sets, and 6.3 kV or 10.5 kV for high voltage applications. Single-phase and three-phase versions are both available in the smaller ratings.
Do you accept L/C and T/T?
Yes. Telegraphic transfer and letter of credit at sight are both accepted, and the payment schedule is agreed in the sales contract before production begins.
What warranty is included?
Twelve months from delivery or 1000 running hours, whichever comes first, covering manufacturing defects. Consumable and wear parts such as filters and belts are excluded. Terms are stated in the contract.
Can you supply spare parts and service later?
Yes. Filters, sensors, control modules, alternators and gasket kits are available for the models we supply, either shipped with the generator set or ordered separately afterwards. Technical support is available by e-mail and WhatsApp.
How are generator sets packed for shipping?
Open-frame sets are fixed to steel frames or packed in fumigation-free plywood cases. Canopy and containerised units are protected with film, strapping and corner protection. Loading drawings are provided before shipment so you know exactly how the container is arranged.
Do you provide OEM and own-brand options?
Yes. We build for our own brand and for customers who supply their own nameplate, colour and documentation. Talk to us about your catalogue requirements and the volume involved.
Do you build gas generator sets as well as diesel?
Yes, and both are built on the same line by the same team. Gas sets run on natural gas, biogas, landfill gas, sewage gas, CNG or LPG from 100 kW to 2000 kW, and are normally specified for continuous base-load duty or combined heat and power rather than for standby.
What do you need in order to quote a gas set?
The gas analysis, meaning the methane content and lower heating value, the available gas flow and pressure, the electrical load profile, and whether you want heat recovery. With those four items we can confirm the rating, the gas consumption in m³/h and the gas train specification.
Send us your specification.
Whether the requirement is a single 100 kW standby set or a containerised power module, we will reply with a technical proposal and a price.
