Performance Characteristics
Excellent Reliability（G-A）
Excellent uptime and serviceability; a wide range of thermal energy; fuel flexibility and environmental adaptability.
Balance And Adaptability (G-B)
The G3500B series is a Cat gas generator set with a number of advanced technologies. It is highly adaptable and can handle gas with a methane value as low as 60 MN. Recently, it has achieved efficient operation of lower methane gas (such as propane); mobility - The G3516B generator set is the world's first gas generator set to achieve lean combustion and is widely used in full-mobile, containerized power stations.
Responsiveness And Durability (G-C)
The specially treated aftercooler core, cylinder head and rear gear train bearings are effective against biogas corrosion; due to the special control architecture, the isolated version of the C series generator set is designed to operate independently of the utility grid. Offering industry choices; special projects, Caterpillar is investing in research and development projects for the use of special fuels (such as syngas, blast furnace gas, coke oven gas and ultra-low concentrations of methane coal) on the C Series platform.
High Electrical Efficiency (G-E,G-H)
The E and H series units increase electrical efficiency to a new level with an improved efficiency of up to 44.7% (1.OPF, ISO); E and H series units are available with tailor-made turbochargers, air systems and Controls; less than $14,000 in oil per year, with a planned overhaul interval of up to 80,000 hours to ensure long-term operation at the lowest possible cost.
