UL PTKQ Certified Facility
Hazardous Location Motor Rebuilds that Maintain Your UL Listing
REM Industrial is UL PTKQ certified to rebuild and recertify Division 1 AC/DC motors – so your equipment returns to service compliant, documented, and ready to pass inspection.
What is UL PTKQ?
PTKQ is UL’s Category Control Number for Motors and Generators, Rebuilt for Use in Hazardous Locations. Shops approved under PTKQ are authorized to rebuild UL Listed HazLoc motors and maintain the Listing when work is performed to UL requirements.
REM’s certified process ensures construction and safety criteria for Division 1 environments are preserved—so equipment is compliant and inspection‑ready.
Rebuilt HazLoc motors under PTKQ are identified by a UL Listing mark on the motor with wording indicating a “Rebuilt Electric Motor for Hazardous Locations.” Keep this label intact for audits and inspections.
