Legacy control systems that are out of production present real risk: repair parts unavailable, software unsupported, and documentation scarce. Drake Controls engineers can assess your existing installation and define an upgrade path to current Woodward platforms including Peak 200, MicroNet, and Atlas II. We cover the full obsolescence spectrum: 723PLUS, UG-series mechanical governors, PG series, EGCP, and other end-of-life systems across turbine, engine, and power generation applications.
