Benefits of 6.8-7150kVA Cat® Diesel Generators: The Durable Defense Against Downtime

Energy For Harsh and Demanding Conditions

Cat diesel generators feature a robust design built to perform under the most demanding conditions. From continuous prime ratings to ISO 8528-5 transient response, we ensure power quality never wavers.

Feature-Rich Flexibility and Modularity

Cat diesel generators meet complex requirements across prime, continuous and standby applications from sound attenuation and paralleling to prime ratings and multiple breakers. As a facility's energy needs grow, their modular design enables fast scaling.

Infrastructure Independence

When the grid fails and gas lines are compromised, Cat diesel generators stand their ground. Engineered for seismic compliance and supported by on-site fuel storage, Cat diesel generators service as the ultimate insurance policy for regions prone to earthquakes, hurricanes or unstable utility connections.

Regulatory Peace of Mind

Cat diesel generators are engineered to run on hydrated vegetable oil (HVO), biodiesel or lower-quality, high-sulfur fuels (up to 2000 PPM) without compromising durability. They also have fully integrated aftertreatment systems to meet stringent emission standards.

A Robust Generator Solution, Backed by Responsive Support

De-risk your operation with the world's most responsive support network. Your Cat dealer offers more than just parts; they offer a
20-year commitment to reliability. With technicians on standby 24/7, we ensure your critical asset is monitored, maintained, and ready to run at a moment's notice.
