Overview#
The Cat C175-16 is a large-format diesel generator set rated from 2,500 to 3,100 ekW for standby and mission-critical applications. Built around Caterpillar's 84.7-liter V-16 SCAC engine with common rail fuel injection and ADEM A4 electronic controls, this platform serves data centers, large industrial facilities, and campus-scale power systems where multi-megawatt capacity is required.
The C175-16 is available in voltages from 220V through 13,800V medium voltage, making it suitable for both low-voltage paralleling arrays and direct medium-voltage distribution. The EMCP 4.2 control panel provides full protective relaying, Modbus RTU communications, and programmable I/O for integration into building management and paralleling systems.

Physical dimensions#
At maximum configuration, the C175-16 measures 312.9 inches long, 113.7 inches wide, and 134.3 inches high, with a dry weight up to 50,500 lb (22,906 kg). Minimum-configuration dry weight starts at 42,750 lb (19,391 kg). Site planning must account for adequate structural support and rigging access for equipment of this size.
Our service experience#
The C175-16 represents Cat's high-power diesel platform. At this size class, proper load banking, fuel quality management, and turbocharger health monitoring are critical to reliability. The dual-turbo V-16 configuration requires balanced attention to both banks during service intervals. The EMCP 4.2 controller provides comprehensive diagnostics and supports paralleling for multi-unit installations.
FAQ#
What is the standby power output of the Cat C175-16?#
The Cat C175-16 is rated from 2,500 to 3,100 ekW standby at 60 Hz / 1,800 rpm. Common configurations include 3,000 ekW at 480V and 3,100 ekW standby for mission-critical applications.
What engine does the Cat C175-16 generator use?#
The C175-16 SCAC -- an 84.7-liter V-16, four-stroke turbocharged-aftercooled diesel with a 175 mm bore, 220 mm stroke, 16.07:1 compression ratio, and common rail fuel injection governed by the ADEM A4 electronic governor. Certified to U.S. EPA Tier 2 Nonroad Equivalent for stationary emergency use.
What are the service intervals for the Cat C175-16?#
Standard Cat C175-16 service intervals are: oil change every 500 hours or 12 months, coolant flush at 6,000 hours, air filter at 1,000 hours. Major overhaul interval is 50,000 hours for the C175 series -- significantly longer than smaller Cat platforms. Annual load bank testing is recommended.
Is the Cat C175-16 EPA compliant?#
Yes. The C175-16 is U.S. EPA Certified for Stationary Emergency Use Only, meeting Tier 2 Nonroad Equivalent emission standards. It also holds UL 2200, IBC seismic certification, NFPA 110, and ISO 8528-5 compliance.
