Benefits of 20-5320kW Cat® Diesel Generators: The Durable Defense Against Downtime.

Energy For Harsh & 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 & 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.

Uncompromised Reliability &
Remote-Ready

Cat diesel engines are built on a 100-year legacy of durability. Where no grid can go and no gas pipeline can reach, diesel generators are ready to provide essential prime power in the harshest of conditions.

Power That Stands
It's Ground

In seismic zones like California and Western Canada, a generator is only as good as its ability to survive the event. Cat diesel generators are available with full seismic certification (IBC), ensuring that your backup power remains operational even when gas lines rupture or structural integrity is compromised.

Dependability That Pays
In The Long-Term

With superior fuel efficency and extended maintenance intervals, a Cat diesel generator is a strategic financial asset that delivers reliability and operational uptime for 20+ years.
