FAQ
Q: What fuel types can the 120KW WC Series generator use?
A: This generator runs on natural gas, LPG, and biogas. The engine comes factory-configured for natural gas; switching to LPG or biogas requires minor fuel system adjustments that can be performed on-site.
Q: Is it suitable for 24/7 continuous operation?
A: Yes. The WC12V138ZLD engine is rated for prime power applications with 500-hour oil change intervals and is built for continuous duty cycles.
Q: What is the natural gas consumption at 120KW load?
A: Approximately 33.5 m³/h at 100% load, 25.1 m³/h at 75% load, and 16.8 m³/h at 50% load. Actual consumption varies with gas quality and ambient conditions.
Q: Does it include an ATS (Automatic Transfer Switch)?
A: The ATS is optional. The generator’s digital control panel (DeepSea or SmartGen) supports AMF (Auto Mains Failure) function, enabling seamless integration with any standard ATS.
Q: What certifications and testing does it have?
A: Each unit is ISO 8528, CE, and EPA certified. A factory load test report documenting voltage regulation, frequency stability, and thermal performance is provided with every generator.
