A major Middle Eastern oil refinery recently completed a critical equipment upgrade by replacing several aging high-voltage drives with new wolong nanyang motor 11kV ATEX Certified Motors. The change came after an internal safety audit revealed that the older motors were struggling to maintain stable operation under high ambient temperatures and fluctuating load conditions, increasing the risk of ignition in hazardous areas.

The newly installed 11kV ATEX-rated units were selected for their reinforced insulation system, explosion-proof construction, and robust mechanical design. During the first operational month, refinery engineers documented a noticeable improvement in temperature control: the motors consistently ran 10–15°C cooler than the outgoing models, even during peak crude-oil pumping cycles.

One incident highlighted their value. A pressure-surge event in the pipeline system triggered an automatic emergency shutdown, and while several pieces of equipment showed stress damage, the wolong nanyang motor 11kV ATEX Certified Motors remained fully intact. Post-incident inspections confirmed that their flameproof housing and strengthened terminal boxes effectively prevented internal sparks from reaching the surrounding environment.

Since implementing the upgrade, the refinery has reported a 30% reduction in equipment-related safety alerts in ATEX Zone 1 areas. Management now plans to extend the use of these motors to compressor stations and vapor-recovery units to further enhance operational safety and reliability.
