Import 500kw Biogas Genset — Buy in wholesale FOB from Supplier in China

The Weifang Naipute 500kW biogas genset is an integral-structure generating set rated at 500kW with a 900A output at 400/230V and 50Hz, designed for continuous operation on biogas or natural gas fuel. The power unit uses an NW363D53TL inline eight-cylinder gas engine with 170mm bore and 200mm stroke, delivering 530kW at 1500rpm through turbocharged, aftercooled, premixed lean-burn combustion. Electrical excitation is brushless AVR, maintaining steady-state voltage regulation within ±1% and transient voltage recovery between -15% and +20%. The genset measures 3850mm x 1180mm x 1980mm and weighs 6850kg net, suited for fixed installation at biogas plants, agricultural digesters, and industrial cogeneration sites.

The engine employs electronically controlled ignition with pre-mixed lean-burn technology to reduce NOx emissions and improve methane fuel efficiency compared to stoichiometric gas engines. Silicon steel laminations in the alternator core minimise eddy current losses, while copper windings and carbon steel housing provide durability for continuous-duty applications. The ±0.5% steady-state frequency regulation and 5-second frequency stabilisation time meet grid-code requirements for parallel operation in many developing markets. Cylinder displacement totals 36.3 litres across the inline eight configuration, with electrical speed governing maintaining 1500rpm under varying load. The unit can switch between natural gas and biogas fuel types, though methane content, hydrogen sulphide levels, and moisture content in biogas must be managed to prevent engine corrosion and valve recession.

Primary buyers are biogas plant developers, agricultural cooperatives with anaerobic digesters, and industrial facility managers seeking combined heat and power (CHP) solutions. The genset serves markets in Southeast Asia, Africa, and Latin America where biogas infrastructure is expanding and grid reliability is variable. Before purchasing, confirm the methane concentration and calorific value of the available biogas, as the engine tuning and de-rating factor depend on fuel quality. Also verify with the supplier whether heat recovery exchangers, exhaust silencers, and gas cleaning trains are included or must be sourced separately, since CHP economics rely heavily on heat utilisation efficiency.

Weifang Naipute Gas Genset Co., Ltd. is located at No. 1599 Xinyuan Road, Economic and Technology Development Zone, Weifang, Shandong Province, 261000, China. The company holds a Harbor trust tier on the platform, though like many specialised genset manufacturers in the Weifang cluster, it shows zero percent response rate and no average response time data. Buyers should initiate contact through multiple channels and expect to follow up persistently to obtain quotations and technical clarifications.

The supplier focuses specifically on gas-fuelled generating sets, distinguishing itself from the broader diesel genset manufacturers nearby. Its product line centres on biogas and natural gas engines with power ratings that appear to span from smaller agricultural units up to this 500kW class. The listing does not disclose factory floor area, annual output, R&D headcount, ISO certification status, or reference installations, so buyers should request a company profile, factory audit report, and customer references in their target market. The use of a proprietary NW363D53TL engine designation suggests either an in-house development or a licensed technology from a domestic engine partner, which buyers should verify to assess long-term parts availability.
