A petrochemical storage and transfer facility in Southeast Asia recently completed an upgrade of its drive systems in classified hazardous zones. The project required motors that could operate continuously in environments with flammable gases and strict safety regulations. After a technical evaluation, the operator selected the Wolong explosion proof motor range, built on a robust 3 phase induction motor platform, for use on pumps, compressors, and ventilation equipment.

Safety compliance was the primary concern during procurement. The Wolong explosion proof motor design incorporates reinforced enclosures, flameproof structures, and carefully controlled surface temperatures to reduce ignition risks. These features allowed the motors to meet local and international explosion protection requirements while maintaining the simplicity and reliability of a 3 phase induction motor.

Installation and commissioning progressed smoothly, as the motors were compatible with existing control systems and variable frequency drives. During trial runs, engineers observed stable starting characteristics, low vibration levels, and consistent torque output under both full-load and partial-load conditions. The proven 3 phase induction motor structure helped ensure predictable performance even during frequent start-stop cycles.

After several months of operation, plant operators reported improved reliability compared with older equipment. The Wolong explosion proof motor units showed strong resistance to dust, moisture, and chemical exposure, reducing unplanned shutdowns and maintenance frequency. Energy consumption data also indicated efficient performance for continuous-duty applications in hazardous areas.

This case highlights how a Wolong explosion proof motor combined with a 3 phase induction motor design can deliver both safety and operational efficiency in demanding industrial environments. For projects operating in explosive atmospheres, this solution offers a practical balance between regulatory compliance, durability, and long-term performance.
