Ex Motor Repair (IECEx)

Arabian Barq is an IECEx Certified Service Facility (certificate IECEx UL S0019, issued by UL Solutions on 8 September 2026) for the repair, overhaul and reclamation of explosion-protected motors and generators, with or without terminal boxes, under the IECEx 03 scheme and IEC 60079-19:2019. Motors that protect refineries, gas plants and petrochemical units are repaired under documented procedures that preserve every explosion-protection feature, and are returned with the repair records and marking the standard requires.

Every Ex repair starts with verification of the machine's certification: Ex marking, certificate references, gas group, temperature class and type of protection are recorded and the certificate conditions are checked before any work is scoped. A repair that would compromise the certified design is not carried out without the manufacturer's data or a documented engineering justification.

Flameproof (Ex d) enclosures are measured at every flame path, gap and thread engagement against the certified drawings and restored by machining, sleeving or reclamation to the specified tolerances. Increased-safety (Ex e) windings are rewound with the original winding data and insulation class so that temperature rise and tE time remain within certification. Non-sparking (Ex n / Ex ec) and pressurised (Ex p) machines follow the same controlled route.

After repair the machine is tested electrically and mechanically, fitted with the repair marking required by IEC 60079-19 and released with a repair report that lists the work performed, the critical dimensions measured and the test results, giving your inspectors the traceability they need.
