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.
Concepts NREC offers rerate packages for the following chillers:
