Retrofit改造升级
Retrofit is the act of upgrading existing machinery or automation by adding new controls, sensors, drives, software, or safety functions while retaining the base frame, structure, and major mechanical parts. In manufacturing and technical documentation it appears in engineering change requests, upgrade specifications, safety-modification descriptions, commissioning records, and supplier quotations, where translators must clarify the scope of retained and replaced parts and the resulting performance changes.

Where this term appears
In translation projects, retrofit appears in machine upgrade manuals, field service bulletins, capital-expenditure requests, safety modification instructions, and control-system migration documents. It is often paired with words like “retrofit kit,” “retrofit in the field,” or “retrofit solution.” Translators encounter it when a manufacturer describes how older equipment can be updated to meet current performance or safety expectations without a full replacement.
Translation checks
A frequent error is translating “retrofit” as “repair,” “refurbishment,” or “overhaul.” Those terms imply restoring the original condition, while a retrofit adds new capability or safety functions. In project scope statements and safety documentation, the difference affects costs, schedules, and whether the machine is considered modified. Another mistake is omitting the used-versus-new scope, so readers cannot tell which components remain existing.
Keep the term aligned across your files
Check equipment names, units, safety instructions and interface labels against the source and approved references. Confirm any market-specific document requirements separately.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
