Rerating Provides Greater Capacity
and Improved Efficiency

The rerating of turbomachinery equipment can provide greater capacity and improved efficiency, allow for a change in process requirements, and offer solutions to operating problems while avoiding or significantly deferring the need to replace expensive machinery. Considering the alternatives of accepting less than optimum performance or buying new equipment, an economical rotating element replacement is often the most cost-effective and lowest-risk choice for improving machine performance.

Increase Component Life and Reliability -
Lower Power Consumption

Older machines that are mechanically reliable can be maintained, upgraded, enhanced, or modified to meet present operating requirements and environmental standards. Rerating can often increase component life and reliability while lowering power consumption without diminishing capacity, as well as eliminate equipment surging, vibration, and other design problems.
