The 300kW prime power perfectly matches the load demand of small and medium factories, regional construction and commercial backup scenarios. With 330kW standby power for 10% peak overload, it avoids excessive power redundancy and extra fuel consumption, effectively lowering upfront investment while guaranteeing stable power for key equipment.
The reinforced Yuchai MJ series engine features optimized heat dissipation and sturdy structure, adapting well to dusty and high-temperature conditions at remote mining satellite stations and construction sites. It runs steadily with low failure rate even where after-sales support is limited.
Equipped with a 750L large fuel tank, it can run continuously for 18 hours at 75% load. With economical fuel consumption within 212-220 g/kW·h, it reduces refueling frequency and long-term operating expenses, bringing obvious cost advantages for budget-sensitive regional projects.
Class H winding insulation delivers outstanding heat resistance for long-time standby operation. IP21 protection defends against dust and dripping water. The dual design ensures safe operation both indoors for commercial facilities and outdoors on construction sites, protecting various sensitive electrical devices.
Main service parts are arranged for easy access, paired with an intuitive LCD monitoring panel and 500-hour long maintenance cycle. On-site staff can complete daily inspection and basic maintenance easily, lowering reliance on professional technicians and cutting labor costs.
