Yes, I would like to receive future marketing communications (such as email) from Caterpillar Inc., its affiliates and subsidiaries worldwide and the Caterpillar dealer network. Regardless of whether you decide to receive these marketing communications, Caterpillar will continue to send service/transactional messages, including those that have to do with any accounts that you may have with us.


The C175-16 diesel generator sets are made to meet your mission critical, continuous, standby and prime applications, and match your power standards. Producing reliable power from 2500 to 3000 ekW (3100 ekW without fan) in 60 Hz, each generator set has been designed to meet ISO 8528-5 transient response requirements and to accept 100 percent rated load in one step. Our C175-16 generator sets range from low fuel consumption systems to EPA Stationary Emergency (Tier 2). Leading innovation means some models offer emissions reduced by up to 90 percent — it's technology that has benefits well beyond todays regulations. Seismic certification is also available for select models, maintaining your power after unexpected disturbances. Our integrated control system, including ATS and switchgear, ensures a consistent power supply and connection to your fleet through on-site and remote monitoring options. Our EMCP 4 control panel provides expandable controller options, with management and diagnostic tools, and a user-friendly interface. It's not just quality that matters but customization, choose from a broad range of accessories and bolt-on system expansion attachments. Find flexible packaging to fit unique spatial requirements and environmental conditions. Our C175-16 generator sets are developed for such prerequisites, so that you can meet your specific power needs. For added safety select from one of the UL 2200 and CSA certified package options.
