Engineered specifically to comply with the European Union ATEX Directive 2014/34/EU and optimized for premium dynamic industrial tasks across Italian logistics and gas lines.
Italy maintains one of Europe's largest chemical, oil-refining, and pharmaceutical processing industries, centered around industrial clusters in Lombardy, Emilia-Romagna, and Sicily. Due to the high density of flammable substances, toxic gases, and fine dust involved in these processes, local regulations mandate strict compliance with European ATEX directives for all dynamic equipment.
Additionally, Italy’s major maritime shipping terminals, such as Genoa and Trieste, require highly specialized low-voltage AC explosion-proof motors to run fuel transferring pumps, dry-bulk conveyor lines, and heavy-duty industrial ventilation hoods. Local EPC (Engineering, Procurement, and Construction) companies increasingly look for international manufacturers who can combine strict CE conformity with high-efficiency motor ratings (IE3 and IE4) to satisfy Italy’s aggressive energy conservation mandates.
According to Italy's D.Lgs. 81/08 occupational safety laws, installations inside hazardous environments must guarantee zero sparking risks. Motors running at low voltage (typically 380V to 690V) must not only prevent explosions but also resist saline corroding agents prevalent along the vast Mediterranean coastline.
Explosion-proof motors serve as the critical backbone for safety and production integrity across heavy global processing industries.
The global market is governed by two major standard frameworks: IECEx (International) and ATEX (Europe). Parallel standards like NEC (North America) dictate strict construction differences in junction box seals, thermal tolerances, and spark suppression path clearances.
Global carbon reduction laws are driving the retirement of legacy IE1 and IE2 explosion-proof induction motors. Contemporary installations mandate IE3 (premium) and increasingly IE4 (super-premium) and permanent magnet IE5 configurations to limit running temperatures.
Faced with volatile regional manufacturing costs and localized delivery holdups, international buyers require manufacturers with globally distributed production footprints capable of bypassing regional trade blocks.

Over decades of intensive development, Wolong has established 3 core global manufacturing hubs, 39 advanced production plants, and 3 high-tech R&D complexes worldwide.
Wolong's portfolio integrates world-renowned industrial heritage brands, providing explosion-proof induction motors with structural resilience and efficiency certifications for critical projects globally.
Partner with Shaanxi NanfangHow Shaanxi Nanfang Motor and Wolong merge state-of-the-art Chinese supply chain efficiencies with certified European design parameters.
By leveraging Wolong's massive raw material procurement power, advanced automated robotic assembly, and digitalized quality monitoring systems, we bypass the conventional high overheads that restrict Western manufacturers. This enables us to offer European-spec ATEX low-voltage motors at a highly competitive total cost of ownership (TCO) without sacrificing quality.
Our centralized manufacturing facilities implement standard Vacuum Pressure Impregnation (VPI) insulation lines, precise centrifugal rotor casting, and robust multi-physics simulation platforms to check mechanical and thermal thresholds before shipment.
Premium components designed to isolate electrical heat and sparks, ensuring long-term reliability in hazardous environments.
Features a squirrel cage configuration. Rotors utilize either centrifugal casting or die-cast pure aluminum. For high-capacity models, copper bar rotors are secured using advanced welding. A protective ring design maintains balance during high-speed, variable frequency operations.
Crafted using premium polyester film and reinforced glass cloth, coupled with high-mica tapes. Following the VPI process, the stator coils show high resistance to moisture, chemicals, and temperature fluctuations, meeting Class F and Class H insulation requirements.
Engineered through advanced structural and fluid multi-physics simulations. Made of high-tensile cast iron, the motor frame exhibits excellent thermal dissipation and structural rigidity to handle high impact shocks and minimize operational vibrations.
Comprises a streamlined body, air guide cylinder, protection window, and dampening plates. Optimizes airflow distribution to reduce noise levels, with an IP22 design rating that prevents accidental contact with the fan.
A rich history of premium acquisitions, bringing century-old engineering brands under a unified technological and production banner.
Acquired in 2011, ATB is one of Europe's top motor manufacturers, containing legendary sub-brands like Morley for mining applications and Laurence Scott for naval systems.

Boasting over a century of experience in motor design, Brook Crompton has built a complete range of low, medium, and high-voltage AC motors designed to operate reliably in hazardous areas.

Since 1882, Schorch has set the standard for high-performance drives in petro-refining and power generation. Wolong also manages OLI, a global leader in high-performance vibration motors.

Providing reliable performance across critical and high-exposure industrial applications throughout the Italian peninsula.
Low-voltage variable frequency (VFD) motors configured to drive high-pressure gas compressor packages, marine extraction equipment, and ventilation systems on platforms off the coast of Ravenna.
Equipping offshore mooring terminals and pipeline transfer manifolds with reliable flameproof motors (Zone 1 Group IIB T4) that operate reliably under continuous cycle patterns and marine corrosion risks.
Providing highly efficient IE4 explosion-proof motors (such as the WEBP3 and WEX3 series) to drive bulk chemical storage agitators, powder mixers, and industrial exhaust networks.
Compliance documentation enables seamless integration of our electric motors into complex global supply chains.

Key design developments shaping low-voltage flameproof motor designs for the next decade.
Modern hazardous area operations are moving away from reactive maintenance. Integrating ATEX-certified vibration sensors, bearing thermal couplers, and winding monitors allows real-time data feeding to plant SCADA systems. This aids operators in detecting insulation degradation or bearing wear before a spark condition arises.
Using VFDs with explosion-proof motors introduces harmonic heating stresses on stators. The future of flameproof technology lies in matched-pair motor-drive systems, where internal thermistors interface with smart drives to cut power if localized temperatures exceed safe limits.
