250kW Diesel Generator Watchdog
Total security for the 250kW Diesel Generator.
Why it matters: Heavy-duty open generators often run in hot, dusty rooms. A sudden drop in oil or spike in temperature goes unnoticed until it's too late. This module is your automated mechanic.
Operating an open base-frame generator requires reliable fail-safes. Whether a stray piece of debris blocks the radiator or a sudden electrical fault occurs downstream on your site, the control module instantly isolates the problem, stopping the engine dead in tracks to preserve its mechanical integrity.

Frequently Asked Questions
Is 250kW enough power for my facility?
A typical 250kW generator can power lighting, refrigeration, water pumps, and several air conditioning units simultaneously. For a standard facility under 300m², 250kW is usually sufficient for essential loads. We recommend listing your equipment wattage for a precise sizing check.
How much fuel does the 250kW generator consume per hour?
At full load, the 6126ZLD engine consumes approximately 7–8 litres of diesel per hour. At 75% load (typical operating condition), fuel consumption drops to around 5.5–6.5 litres/hour. The built-in base tank supports ≥8 hours of runtime at full load.
Can I install this open type unit outdoors permanently?
No. Open type generators must be installed indoors in a dedicated, well-ventilated generator room or under a protective shelter. They are not waterproof and should not be exposed to direct rain or extreme weather without a canopy.
What does the "Four Protection System" controller do?
The standard controller monitors four critical parameters in real-time: oil pressure, coolant temperature, engine over-speed, and over-current. If any parameter exceeds the safe threshold, the controller will automatically shut down the engine to prevent damage. It can be upgraded to a Full Auto (ATS) system for unmanned, automatic operation.
What is the difference between the brushed and brushless alternator options?
The default half-copper brushed alternator requires periodic brush replacement but is cost-effective for standard applications. The brushless variants (half-copper or full-copper) eliminate brush wear, provide cleaner power output, and are more suitable for sensitive electronics or installations with minimal maintenance access.
Do you offer wholesale or bulk order pricing?
Yes. As a direct manufacturer, we offer competitive wholesale pricing for bulk orders. The listed price of $5,335 reflects the default single-unit FOB China price. Please contact us with your quantity and specifications for a tailored quotation.
