Caterpillar Inc. is pleased to announce the latest addition to its series of Cat® generator sets designed to deliver the lowest owning and operating costs in the market. The G3512H is the third of the H-Series product line now available for operation on natural gas fuel. This generator set is currently offered at 1500 kWe power output at 50 Hz and 60 Hz.
The G3512H leads the industry, with the lowest owning and operating costs in its class through improved electrical efficiency of up to 44.6% /60Hz and 44.9%/ 50Hz (ISO, 1.0 p.f.) and decreased maintenance costs. Recent 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 (1.5 to 5 psi/ 10.2 to 34.5 kPa) that facilitates maximum performance on pipeline natural gas. The major overhaul period of the G3512H is 80,000 hours with an in-frame maintenance interval at 40,000 hours.
