375Kva~1500Kva Cummins Gas Generator

The WD-CU is a Cummins-powered natural gas generator set built in ratings from 375 kVA to 1500 kVA, equivalent to 300 kW to 1200 kW of rated continuous power. It is assembled around Chongqing Cummins K19N, K38N and K50N spark-ignition gas engines, covering twelve models from the K19N-G1 at 300 kW up to the K50N-G12 at 1200 kW, each delivered as a complete package with engine, water tank, gas system and imported valve group as well as an open-loop intake and exhaust system and intake valve group cooling. The engines use precision electronic control, enhanced combustion and deep Miller cycle technology to reach 42% thermal efficiency with roughly 6% integrated gas saving, while hydraulic automatic valve adjustment extends maintenance intervals to 300,000 km and overhaul cycles to 10 years. A high-temperature-resistant turbocharger and precision gas injection system deliver up to 720 HP maximum power and 3600 N·m maximum torque with strong low-speed torque, and Smart Brain 3.0 control with variable valve timing keeps output stable in harsh conditions, including cold starts at -25 degrees Celsius. Natural gas is the standard fuel, with LNG, biogas, LPG, hydrogen and biomass gas available on separate quotation, and the sets support multiple gas sources through the same fuel system architecture. Typical duty covers round-the-clock prime power for construction and infrastructure sites, mining and resource extraction in extreme conditions, agricultural irrigation and agro-processing, and data centers and telecom towers requiring seamless automatic power switching. The units also serve as a grid-stability backbone for commercial and residential loads. Each set is shipped as an open-loop configuration with intake and exhaust system, water tank, gas system and imported valve group, packed in wood, steel or plastic film packaging. Cummins' worldwide authorised network supports the units with genuine parts, professional maintenance, intelligent diagnostics and cloud-based digital solutions, and transferable extended warranty options are available in line with regional regulations.
