With Rolls-Royce Aero Engine Technology

A single stage boost compressor, improved vane cooling, higher strength turbine blades and many other enhancements have been incorporated for improved performance, durability and operating cost.

The aero-derivative design of the Industrial 501-K series engine provides a lightweight, modular product that helps lower operating costs through improved fuel consumption, extended hot section life and ease of maintenance.

Siemens knows there is more to customer satisfaction than manufacturing a quality gas turbine engine. Beginning with the finest designs, the most advanced manufacturing techniques and rigid verification testing, our team continues to serve our customers with a global network of support. These power products are backed by this comprehensive service worldwide.

The aero-derivative Industrial 501-KB7 engine has an overall improvment in fuel consumption
