WPG28F1 20kw 50Hz, Open Frame Large Generator Sets Weichai Factory Direct Sales

Engineered for durability, the WPG28*1 houses a high-strength engine built with a cast iron gantry-style block that offers excellent stability. It incorporates a one-piece forged crankshaft and independent cast iron cylinder heads with wet liners, further enhancing longevity. Aluminum alloy pistons with integrated oil cooling channels boost efficiency while reducing wear, ensuring the engine remains resilient under rigorous conditions.

The generator’s power generation is facilitated by a brushless, 4-pole alternator with an IP23 rated drip-proof rotor design. Equipped with H-class insulation and a low reactance configuration, it maximizes efficiency and minimizes energy losses. The system can withstand sudden surges of up to 300% overcurrent for 10 seconds and is cooled continuously via a centrifugal blower system, maintaining stable operation.

Monitoring and control are simplified with an advanced, user-friendly module controller featuring a backlit LCD display. This interface provides real-time insights into operational parameters such as engine speed, frequency, voltage, current, oil pressure, coolant temperature, and fuel levels. Additionally, it displays critical alerts, warnings, and engine status updates to ensure safe and efficient operation. The integrated hour meter allows for precise maintenance planning, making the WPG28*1 an ideal solution for those seeking dependable, intelligent power management.
