500kW Diesel Generator Command
Managing the 500kW Diesel Generator expertly.
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.

Core Advantages of the Open-Frame Build
Heavy-Duty Skid Base
Built on a rigid, vibration-isolating steel frame. It ensures structural integrity during heavy-load operation and simplifies forklift handling or permanent concrete pad installation.
Maximum Cooling Efficiency
Without a restrictive canopy, the oversized radiator and cooling fan benefit from unrestricted ambient airflow, drastically reducing the risk of overheating in high-temperature engine rooms.
Unrestricted Maintenance Access
Mechanics have 360-degree access to all engine components. Oil changes, filter replacements, and alternator inspections can be performed in half the time compared to enclosed units.
Highest kW-to-Cost Ratio
By eliminating the cost of a weather-proof enclosure, your investment goes entirely toward raw megawatt-class power generation. It’s the most cost-effective solution for dedicated indoor generator facilities.
Seamless Plant Integration
The open architecture makes it incredibly straightforward to pipe external exhaust systems, connect high-capacity bulk fuel tanks, and integrate with existing industrial electrical layouts.
WP13ZLD Core Reliability
Powered by the proven Weifang WP13 engine block. Renowned for its massive displacement, heavy-duty torque tolerance, and the global availability of affordable replacement parts.

Frequently Asked Questions
Is 500kW enough power for my facility?
A typical 500kW generator can power lighting, refrigeration, water pumps, and several air conditioning units simultaneously. For a standard facility under 300m², 500kW is usually sufficient for essential loads. We recommend listing your equipment wattage for a precise sizing check.
How much fuel does the 500kW generator consume per hour?
At full load, the WP13ZLD 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 factory-direct supplier, we offer competitive wholesale pricing for bulk orders. The listed price of $11,169 reflects the default single-unit FOB China price. Please contact us with your quantity and specifications for a tailored quotation.
