Modernization of existing equipment with newer technology without complete replacement, extending its useful life and improving performance at lower cost than new equipment investment. Typical examples: installing a variable frequency drive (VFD) on a fixed-speed motor (20-50% energy savings), updating an obsolete PLC to a current platform, replacing plain bearings with roller bearings, installing IIoT sensors for online monitoring. Typical ROI: 12-36 months. Economic alternative for equipment with obsolete spare parts.
