Engineered for absolute safety in French ATEX Zones 1 and 2, optimized for high efficiency and hazardous duty performance.
As France accelerates its transition under the "France 2030" investment plan, industrial sectors such as chemicals, green hydrogen production, offshore maritime infrastructure, and carbon capture are restructuring. These high-end processes require absolute safety compliance. Under the European Union ATEX Directive 2014/34/EU and French national labor safety codes (Code du Travail), selecting highly robust, low-voltage explosion-proof AC motors is critical for mitigating ignition risks in volatile environments.
Whether it is in the massive chemical clusters of Fos-sur-Mer, the oil refining hubs of Le Havre, or the pharmaceutical plants in Auvergne-Rhône-Alpes, low voltage explosion-proof motors act as the primary movers of pumps, compressors, and blowers. Sourcing partners require deep engineering expertise, rigorous compliance documentation (CE, Nemko, ATEX certificates), and high energy-efficiency standards (IE3, IE4, and emerging IE5 profiles) to minimize both operational risk and lifecycle emissions.
Shaanxi Nanfang Motor Technology Co., Ltd, as the authorized globally recognized distributor of Wolong Electric, bridges this technical gap. By coupling Wolong’s extensive international brand legacy (including ATB, Brook Crompton, Schorch, Laurence Scott, and Morley) with state-of-the-art smart factory manufacturing, we deliver customized, high-reliability solutions directly tailored for French OEMs, EPC engineering firms, and end-users.
Traditional motor operation in explosion-hazardous areas experiences peak thermal load during starting phases. Sourcing Variable Frequency Drive (VFD) motors like the WEBP3 and YBBP series allows French plant engineers to control starting torque and inrush currents, keeping temperatures well below the ignition limit of specific volatile gases (T4/T5/T6 classification).
✓ Optimized VPI Insulation preventing micro-discharges.
✓ Accurate temperature feedback with PTC/PT100 sensors directly in stator windings.
✓ Advanced cooling geometries for lower delta-T operation.
Shaanxi Nanfang Motor Technology Co., Ltd. is the premier authorized global supplier of Wolong Electric Drive Group Co., Ltd. Established in 1984 and listed on the Shanghai Stock Exchange in 2002 (Ticker: SH600580), Wolong has grown to become the world’s leading manufacturer of motors and variable speed drive control systems.
Through deliberate, strategic acquisitions of century-old European electrical icons, Wolong has unified pioneering engineering methodologies under a single global brand portfolio. This legacy portfolio comprises ATB (Austrian drive leader), Brook Crompton (high-efficiency motor pioneer), Schorch (heavy duty industrial design), Laurence Scott (low inrush marine generators), and Nanyang Explosion Protection Group (CNE), China’s largest base for explosion-proof scientific research and production.
This combined technical capability ensures that every motor delivered to our partners in France is backed by decades of European application engineering experience, manufactured in highly optimized global centers of excellence.
Under the hood of Wolong's explosion-proof AC low-voltage induction motors.
Utilizing high-purity centrifugal aluminum casting or precision-controlled die casting, our squirrel-cage rotors guarantee structural uniformity. For heavy-duty French applications requiring severe starting sequences, customized copper bar rotors with advanced end-ring welding technology are deployed. This maintains structural integrity under thermal expansion and optimizes starting torque properties.
Stator coils are constructed from polyester-film-reinforced mica tapes. The finished stator core assembly undergoes a precise Vacuum Pressure Impregnation (VPI) cycle, sealing the motor against moisture, high humidity, corrosive chemicals, and thermal shock. This offers high dielectric strength and complies with strict European standards for motor survival in aggressive environments.
Utilizing a digital multi-physics simulation platform, the cast-iron or steel motor frames are engineered with high mechanical redundancy. This configuration ensures rapid thermal dissipation, isolates structural resonance frequencies, and resists external mechanical impacts, keeping vibrations minimal and bearing lifespans high.
Comprising a specialized air guide cylinder, protective window, and acoustical silencing plate, the IP22/IP55 fan hood reduces dynamic energy losses and minimizes overall noise levels. Its side-inlet design optimizes air passage profiles, making it highly effective even when placed close to adjacent machinery or enclosures.
How our global brand portfolio powers heavy industries across France and the world.
In 2011, Wolong acquired the Austrian ATB Group. This acquisition integrated the Morley brand, which has a 130-year legacy in underground mining, and Laurence Scott, the supplier of heavy-duty low-starting-current motors for naval vessels and power plants. This provides robust high-specification electrical equipment for French underground operations and marine environments.
Brook Crompton is a pioneer in highly efficient electric motor designs (Premium "W" and "10" series). Alongside Schorch (established in 1882), which sets standards for high-quality driving systems, they supply energy-efficient, robust drive systems to French petrochemicals, oil and gas, shipbuilding, and water treatment projects.
By integrating Nanyang Explosion Protection Group (CNE) in 2015 and acquiring General Electric's commercial and industrial motor division in 2018, Wolong gained unmatched technological support. This enables us to provide comprehensive explosion-proof motor configurations to French heavy chemical installations and metallurgical plants.
Purchasing low-voltage explosion-proof motors from our state-of-the-art Chinese manufacturing facilities offers a distinct advantage in terms of both cost and speed. Our production lines utilize advanced automated stamping, computerized VPI impregnation chambers, and digital testing bays. This degree of automation dramatically minimizes mechanical variances, ensuring consistent quality while optimizing production cycles.
Vertical Supply Chain Integration: By sourcing raw copper, silicon steel, and precision-cast iron components within our domestic industrial hubs, we mitigate the supply chain delays common to European assembly facilities. This allows us to offer shorter lead times for custom explosion-proof configurations.
For French EPC contractors managing complex projects, this means reducing project schedules and ensuring timely commissioning, while maintaining compliance with international standards (ATEX, IECEx, CE).
