Engine line
Weichai Diesel Generators
Weichai is the engine line most often specified when a project is cost-driven and the duty is well understood: a Chinese industrial diesel with a parts network of its own across Southeast Asia, quoted as a new build rather than held as used stock.
A Weichai set is configured for the destination before it is built. The Philippines takes 60 Hz at 220/440 V; Indonesia and Vietnam take 50 Hz at 380/220 V. The set leaves the works wound and set for one of them, so the frequency is settled at the enquiry rather than converted afterwards.

Ratings
What we quote for a Weichai project
Common Weichai requirements. Each rating links to its power range page.
| Rating | Build | Typical duty |
|---|---|---|
| 100 kVA / 80 kW | Silent canopy or open frame | Shops, clinics, small workshops and standby for a single building |
| 200 kVA / 160 kW | Silent canopy, automatic transfer | Commercial buildings, light industry and small plants |
| 300 kVA / 240 kW | Silent canopy | Hotels, malls and hospitals, where the noise limit governs the build |
| 500 kVA / 400 kW | Silent canopy or containerized | Factories, plant rooms and mine camps |
| 800 kVA / 640 kW | Containerized, parallel-ready | Process plants, data halls and larger standby groups |
Questions
Questions we are asked about Weichai sets
Do you hold Weichai sets in stock?
No. The Weichai line is quoted against a requirement, and the set is configured for the destination and built for its voltage and frequency. The used stock we hold is listed on the Cummins, Volvo, Deutz, Perkins, Daewoo and Mercedes-Benz pages.
Which frequency will the set be built for?
The destination decides it. The Philippines runs at 60 Hz and 1800 rpm; Indonesia, Vietnam, Thailand and Malaysia run at 50 Hz and 1500 rpm. A set wound and set for one of them cannot be used on the other, so the frequency is fixed when the order is placed rather than converted afterwards.
How does the Weichai line compare with a Cummins set?
The difference is in the engine line and the price, not in the parts around it: the alternator, the control panel, the enclosure, the protection and the documentation are specified the same way on both. Weichai is the usual answer where the duty is well understood and the budget is set by a tender rather than by a badge.
What alternator is paired with the engine?
Stamford, Leroy-Somer or Marathon unless a tender names another. The alternator make, model and insulation class are quoted with every set, because on a new build the alternator is where a quotation is most often quietly downgraded.
Can you quote against a tender document?
Yes. Send the tender or the technical specification and we return a quotation for the clauses that affect the set: rating and duty, enclosure and noise, control and transfer, documentation and factory testing. Where a clause names a brand or a standard, say so in the enquiry so that the answer addresses it rather than working around it.
