July 23, 2020 – Caterpillar says its new Cat G3520 product line is the first EPA-certified natural gas generator sets on the market rated at 2.0 MW and 2.5 MW for use in 60 Hz power markets. (A low-NOx product is available with emissions down to 0.5 g/bhp-hr.)

Available now, the Cat G3520 is modelled after Caterpillar’s diesel standby product to minimize installation costs and commissioning time. A 20-cylinder engine promises “market-leading load acceptance and transient response”, says Caterpillar. The genset features the EMCP 4 control system, providing engine and genset control, protection and monitoring. (The optional EMCP 4.4 provides the ability to parallel multiple generator sets in various gas and diesel applications.)

The Cat G3520 integrates into building management systems, with ethernet communication capabilities inherent to the control system. The expanded set of features includes complete SR5 generators, gas train, package-mounted radiators, and simplified wiring.
