Diesel Generator Sets

Caterpillar is the world's largest manufacturer of generator sets, offering the largest range of specifications available. If you need a diesel generator set with 6 to 14,040 ekW (7.5 to 17,550 kVA) of power potential, you'll have peace of mind knowing our diesel-fueled generator sets are built to world-class standards, for high efficiency, low fuel consumption and global emissions compliance. Cat® Diesel Generator Sets come in a range of options to match your power needs - so selecting the right diesel generator set for your application, and installing it, is simple.

Diesel Generators - Prime, Continuous or Standby Power

For prime, continuous or standby power service, Cat commercial and industrial diesel generator sets deliver reliable, clean, economical power – even in the most demanding conditions. Each Cat diesel generator set is designed, engineered and manufactured for optimal performance. All major components are tested individually; and once the generator set is assembled, the complete unit is tested at and above 100% of rated load for operation and safety.

A Cat brand generator set offers a huge advantage over all other brands: They all come with the expert service and comprehensive support of your nearby Cat® dealer. It begins with prompt delivery and continues through the life of the diesel genset.
