Overview#
The Katolight D500 is a 500 kW diesel standby generator powered by the MTU/Detroit Diesel Series 60 14.0L engine — a six-cylinder, electronically controlled diesel that represented the most technologically advanced engine in Katolight's industrial lineup. The Series 60 was Detroit Diesel's transition from two-stroke to four-stroke technology and introduced electronic fuel injection to the product line, offering improved fuel efficiency and emissions performance over the older two-stroke models.
Katolight is a discontinued brand, acquired by MTU (now Rolls-Royce Power Systems) in 2006 and rebranded as MTU Onsite Energy. The D500 with the Series 60 engine was a natural pairing given the corporate relationship between Katolight and Detroit Diesel/MTU. These units are found in hospitals, data centers, large commercial complexes, and industrial facilities where 500 kW of standby power was the design requirement.
OnPoint provides full maintenance and repair services for Katolight D500 installations. The Series 60 engine has a well-established parts and service network through the MTU/Detroit Diesel dealer channel, and the generator end components use standard industrial alternators that remain readily available. Properly maintained, these units continue to deliver reliable standby protection.
