37.5kVA (30kW) Open Frame Weichai Diesel Generator Set, 400V 50Hz Three Phase Brushless Genset For Africa, Southeast Asia Worksites
Our 37.5kVA open-frame Weichai genset is a cost-effective heavy-duty power solution centered on stable power core, easy maintenance and multi-scene adaptability. Its core power adopts original Weichai dedicated diesel engine, optimized fuel injection technology reduces fuel consumption while offering sufficient power reserve to withstand motor startup impact loads. The open rack structure fully exposes engine, alternator and filter parts, allowing operators to complete maintenance without disassembling the enclosure, ideal for construction sites and outdoor farms with frequent routine checks. The brushless pure copper alternator with H-class insulation maintains stable voltage output, effectively protecting monitoring, processing and charging equipment from voltage surges. The intelligent digital controller real-time displays voltage, current and running hours, triggering automatic shutdown once abnormal working conditions occur to extend unit service life.
The integrated base frame combines fuel tank and shock absorption devices, lowering vibration during operation and simplifying installation steps. This genset serves dual core values: main power supply for areas without municipal grid and emergency backup power for small factories.
