Caterpillar Inc. has announced the release of the new Cat® G3512, the first natural gas generator set on the market engineered to meet a full suite of critical standby market requirements including NFPA 110 Level 1 Type 10 compatibility, a UL 2200 listing, as well as EPA and CSA certifications. Rated for standby power at 750 kW or 1000 kW at 60 Hz, the generator set is suitable for the emergency standby market in North America.
Ideal for emergency, legally required or optional standby systems, the G3512 is appropriate for office buildings, data centers, retail complexes, schools, government buildings, universities and research facilities.
With an updated package design, the G3512 is modeled after the standby diesel solution to minimize installation costs and commissioning time on-site. A high power density 12-cylinder engine offers market leading load acceptance and transient response. Designed for reliability, this engine is built on established 3500 technology and features a robust design with steel pistons and a protection monitoring system.
Featuring Caterpillar’s new EMCP 4.3 generator set controller, the G3512 easily integrates with building management systems. The expanded set of features also includes complete SR5 generators, gas train, package-mounted radiators and simplified wiring connections.
The G3512 is compatible with NFPA 110 Level 1 Type 10 applications, where backup power is required for mandatory building functions such as egress lighting, elevators, ventilation or data equipment, among others. The G3512 generator set starts and accepts power load in as quickly as 6.5 seconds, depending on conditions at the site.
“The combination of performance, certifications, and other critical customer requirements addressed by the Cat G3512 generator set checks all the boxes for the standby market segment,” said Mike Yohe, product line management with Caterpillar Energy Solutions. “This is built upon a robust diesel 3500 platform with a proven track record, and dependability is critical for customers who use these generators during utility outages.”
