Yuchai 6M Series 250kVA-430kVA Diesel Generator, Prime Power for Large Factory Production

Product Overview

The WOPUSAI Yuchai 6M series 250kVA‑430kVA open‑frame diesel generator set represents high‑power industrial power solution, powered by original Yuchai 6M inline 6‑cylinder heavy‑duty diesel engine, matched with TFW brush‑less all‑copper synchronous alternator. Running at 1500rpm 50Hz, it delivers stable three‑phase 400V/230V power output. Different from brushed alternator models of 6A & 6B series, this 6M series adopts full‑copper brush‑less excitation structure. It supports both mechanical governing and electronic governing options, paired with turbo‑charged inter‑cooled intake and direct‑injection fuel system. Designed for mission‑critical backup scenarios where uninterrupted power is vital. It is widely deployed for data‑center standby power, large‑scale manufacturing base, grade‑A hospital power backup, large commercial complex and heavy‑duty EPC engineering projects.

Product Showcase

Yuchai 6M Series 250‑430kVA High‑Power Industrial Open‑Type Genset This heavy‑duty complete genset assembles Yuchai 6M large‑displacement water‑cooled diesel engine and TFW brush‑less all‑copper alternator, built for non‑stop critical‑load working conditions.

Yuchai 6M inline‑6 heavy‑duty engine covers displacement from 10.3L‑11.7L. It adopts turbo‑charging inter‑cooled intake and direct injection fuel supply. Users can select mechanical governor or electronic governor according to project requirement. Heavy‑duty DC 24V electric starting system guarantees reliable startup under extremely low‑temperature environment. 40℃ large‑capacity standard water circulation cooling system effectively dissipates heat under long‑duration full‑load continuous running. Supporting TFW brush‑less all‑copper alternator comes with H‑class insulation grade and IP23 protection rating, star‑type connection and AVR automatic voltage regulation, power factor 0.8 lag. Brush‑less structure eliminates carbon‑brush wear issue, lowers regular maintenance frequency. Heavy‑duty reinforced base frame greatly reduces vibration during high‑power stable operation.

Key Specifications

Core Advantages

1. Yuchai 6M Large‑Displacement Six‑Cylinder Heavy‑Duty Powertrain Genuine Yuchai 6M heavy‑duty six‑cylinder engine, displacement ranging 10.3L‑11.7L. Turbo inter‑cooled structure optimizes combustion efficiency. Dual governor options (mechanical / electronic) can match different project control requirements. Excellent continuous full‑load performance, suitable for long‑time critical power supply scenarios, far exceeding medium‑power 6B series on peak load capacity.
2. TFW Brush‑Less All‑Copper Alternator, Low‑Maintenance Critical‑Load Solution Different from brushed alternator of 6A/6B product lines, TFW brush‑less all‑copper alternator removes carbon‑brush wearing parts. H‑class high‑temperature‑resistant insulation and IP23 higher‑level protection adapt to humid, dusty industrial environment. AVR keeps voltage stable with sudden large‑load fluctuation. It minimizes routine maintenance workload for unattended data center and hospital power station.
3. Dual Governing Modes To Meet Diversified Project Control Demands Buyers can pick mechanical governor for cost‑controlled projects, or choose electronic governor for higher‑precision frequency stabilization. Large‑flow water‑cooling circulation system avoids overheating risk under non‑stop running. Heavy‑duty 24V starting motor delivers stable cold‑cranking performance for outdoor all‑season deployment.
4. Heavy‑Reinforced Base Frame For Long‑Term Fixed Industrial Installation Whole‑set reinforced welded base relieves high‑power operation vibration. Though the unit has large dimension and weight, inspection ports, oil‑changing ports and filter components are rationally arranged for easy access. Operators can finish periodic overhaul without large‑scale disassembly work, ideal for permanent fixed installation for key facilities.
5. Optimized Total‑Life‑Cycle Value For Mission‑Critical Power Users Rated fuel consumption maintains 220g/KW/h. Even though initial investment is higher than mid‑range gensets, brush‑less alternator cuts frequent carbon‑brush replacement cost. It prevents production & service loss caused by power outage for core facilities, focusing on long‑term reliability rather than merely upfront purchase cost.
