Shaanxi Nanfang Motor Technology Co., Ltd. serves as the premier authorized distributor of Wolong. Wolong Electric Drive Group Co., Ltd., founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code SH600580), has spent over three decades establishing a dominant global footprint. Wolong currently operates 3 major manufacturing bases, 39 advanced factories, and 3 state-of-the-art R&D centers worldwide. Dedicated to the design, production, and lifecycle support of motors and automated control systems, Wolong’s global brand strategy positions it at the absolute forefront of industrial automation and hazardous location technology.
A professional overview of Greece's regulatory environment, industrial demands, and energy transition requirements.
Greece is transitioning into a core energy corridor for the Eastern Mediterranean, highlighted by the Trans Adriatic Pipeline (TAP), the expansion of the Revithoussa LNG Terminal, and the developing floating storage regasification units (FSRUs) in Alexandroupolis. These critical infrastructures, alongside oil refineries like Hellenic Petroleum and Motor Oil Hellas, demand high-grade explosion-proof motors that ensure process safety, reliability under high ambient operating temperatures, and absolute compliance with safety directives.
Beyond oil and gas, Greece has a long-standing agricultural and cement processing infrastructure (such as Titan Cement). Fine grain powders, dusts in food processing factories, and coal dust in traditional power plants present severe combustible dust hazards. This necessitates motors with robust enclosure protection (IP65/IP66) to prevent dust ingress and potential thermal ignition.
As a Member State of the European Union, Greece enforces strict compliance with the ATEX Directive 2014/34/EU (equipment intended for use in potentially explosive atmospheres) and Directive 1999/92/EC (workplace safety in hazardous areas). In Hellenic environments, electrical drive systems must bear the CE mark, the distinctive hexagon Ex symbol, and specific marking indicating the protection concept (such as flameproof "Ex d", increased safety "Ex e", or non-sparking "Ex nA/Ex ec").
Furthermore, marine applications operating in Greek waters—under the regulation of the Hellenic Coast Guard and international shipping classes—require marine-certified components that can resist saltwater corrosion (C5-M painting systems) and comply with both IECEx and maritime classification societies (DNV, Lloyd's Register, ABS, RINA).
We provide multiple European-compliant explosion protection certifications. Our products fully comply with EN/IEC 60079 series standards, guaranteeing seamless integration with Greek installations and smooth customs clearance through European ports.
In alignment with Greece's National Energy and Climate Plan (NECP), which targets drastic energy reductions, we offer IE3, IE4, and ultra-premium IE5 permanent magnet explosion-proof motors. These units significantly lower operating costs and reduce carbon tax liabilities.
How Wolong has integrated the world’s most trusted motor brands to serve complex global and local projects.
In 2011, Wolong acquired a 97.94% stake in ATB Group, one of Europe's top three motor manufacturers. This acquisition integrated leading brands like Morley (synonymous with heavy-duty coal mining drive systems for over 130 years) and Laurence Scott (famed for low starting current systems, nuclear power plants, and marine military applications). This integration gave Wolong an unparalleled capability to supply extremely specialized drives to European infrastructures.
Brook Crompton brought over a century of motor development and structural design to the group. Known for energy-efficient ranges like the "W" and "10" series, Brook Crompton specializes in extreme-environment low and medium voltage motors. Similarly, Schorch (established in Germany in 1882) joined Wolong in 2011, reinforcing the group's presence in high-specification oil, gas, chemical, and municipal tunnel ventilation projects throughout Western and Southern Europe.
In 2015, CNE (Nanyang Explosion-Proof Group), China’s largest explosion-proof research and production center, merged with Wolong, standardizing high-end flameproof motor manufacturing lines. In 2018, Wolong acquired the commercial and industrial motor division of General Electric (GE), gaining legacy engineering blueprints, robust frame technology, and heavy-industry distribution networks that power petrochemical plants, paper mills, and material processing facilities globally.
Deconstructing the structural and material technologies that enable reliable continuous duty in explosive environments.
Features squirrel cage designs utilizing high-purity cast aluminum. Produced via centrifugal or high-pressure die-casting, which yields a monolithic structure that integrates the rotor bars and end rings. This ensures superior mechanical strength and excellent torque qualities. For larger-capacity motors, copper bar rotors are used, applying reliable bar-securing and induction-welding processes. Additionally, the protective ring design of high-speed motors protects against centrifugal deformation under VFD high-frequency operation.
Coils are crafted from high-grade polyester film reinforced with glass cloth and high-mica-content tape. Following the VPI (Vacuum Pressure Impregnation) process, the entire stator core transforms into a fully sealed, moisture-proof, and chemically resistant structure. The finished windings provide outstanding dielectric strength, high thermal stability (Class F/H rating), and resistance to environmental moisture, making them ideal for high-humidity coastal Greek regions.
Our motor frames are engineered using multi-physics structural and fluid simulation platforms. Constructed from high-strength cast iron or welded steel plate alternatives, the frame features exceptional structural stiffness, optimized heat dissipation fins, and high inherent vibration isolation margins. Designed to endure significant mechanical shocks and minimize thermal stresses, this layout keeps overall motor vibration minimal and maintains low operational temperature rises.
Comprises a light-weight fan cover body, air guide cylinder, protective window, and silencer plate. This layout optimizes air pathing, reduces energy loss-induced noise, and prevents resonance. The side air inlet avoids blockages at the rear of the motor, maintaining ventilation. Fitted with sound-absorbing materials and achieving an IP22/IP44 protective rating, it ensures mechanical safety by preventing accidental contact with rotating fan blades while reducing audible decibel levels.
Meeting the demands of international trading hubs and heavy engineering safety policies.
To support global supply chains and simplify engineering sourcing, Wolong maintains a broad range of product certifications. This enables our explosion-proof motors to operate worldwide:

Aligning development with smart energy policies, predictive maintenance, and international gas networks.
The design of electrical machinery in hazardous zones is moving beyond baseline explosion isolation. Modern Greek engineering firms demand intelligent diagnostics. The inclusion of PT100 temperature sensors in windings and bearings, alongside Ex-certified vibration sensors (such as OLI vibration systems), enables operators to implement predictive maintenance. This helps prevent catastrophic insulation breakdown or bearing failures before they occur.
Additionally, the expansion of green hydrogen project planning under the European Union’s decarbonization pathway requires motor designs that resist the explosive qualities of hydrogen gas. Hydrogen is classified as a Gas Group IIC substance under EN/IEC standards. Operating safely in this environment requires small experimental flameproof joint dimensions, highlighting the need for advanced manufacturing precision in our next-generation motor lines.
