CHP2500

Displacement: 5956 in³ / 97.5 l
Bore: 6.7 in / 170 mm
Stroke: 8.5 in / 215 mm

The CHP2500 is an enclosure standardized for natural gas-fueled Cat® G3520H engines rated 2.5 MW, with generator rated for 4160V for combined heat and power (CHP) applications. In CHP applications, Cat gas generator sets simultaneously provide electricity for electrical loads and heat energy for a facility's thermal requirements. Caterpillar will offer customers complete CHP solutions eliminating the need to outsource additional engineering or project management.
