This generator set is currently offered at 2500KWe power output at 50Hz and 60Hz.

The Cat G3520H was developed to meet customer demands for improved return on investment, extended-duty combined heat and power (CHP) and continuous electric power applications.

The new generator sets are designed to be effective in continuous-duty applications and can be used in industrial and commercial facilities such as mines as well as in distributed generation power plants. The increased power density of the generator sets provides a compact size that helps reduce installation costs.

The G3520H leads the industry with the lowest owning and operating costs through improved electrical efficiency of up to 45.3% and decreased maintenance costs. New product developments, including cuffed cylinder liners, updated valve stem sealing, and increased valve train lubrication have minimized the number of maintenance events and reduced oil consumption over previous levels.

Additionally, the new model features an open combustion chamber design, which allows use of a low-pressure fuel system that facilitates maximum performance on pipeline natural gas.

The major overhaul period of the G3520H is 80,000 hours with an in-frame maintenance interval at 40,000 hours.

The H Series has accumulated more than 100,000 hours and is built on the legacy of the proven G3500 generator set platform with over 10,000MWe of power installed worldwide.

The G3520H generator set is easily tailored to specific applications with a wide selection of Cat SR5 generators and attachments, premium controls, exhaust options, remote annunciator modules and battery chargers.
