Caterpillar has announced the release of the new Cat® CG132B, which it describes as “the first natural gas generator set in its class engineered to meet an electrical efficiency of 43.5%.” It is rated for continuous power at 400, 600 and 800 kW for both 50 and 60 Hz.
A flanged generator set concept includes a vibration-decoupled base frame to lower installation costs while improving reliability, Caterpillar says. Also, the turbocharger is now water cooled and features a wider combustion air temperature window, while a modified combustion chamber decreases knock sensitivity and pollutant emissions while also reducing service requirements.
Oil change intervals have significantly improved due to enhanced oil management and operation hours until the first major overhaul have been increased from 64 000 to 80 000 on natural gas.
