Specially optimized for industrial systems and ATEX compliance requirements in Barcelona.
Barcelona and the wider Catalonia region constitute one of Southern Europe's most dynamic industrial hubs. From the extensive chemical complexes in Tarragona to the pharmaceutical manufacturing facilities in Martorell and Vallès, safety compliance is paramount. Volatile substances, dust environments, and corrosive sea-air conditions necessitate robust, explosion-proof drive solutions to safeguard personnel and assets.
As a dedicated distributor and manufacturer support network, we supply high-performance AC Low Voltage Explosion-Proof Motors custom-tailored for these challenging environments. Our drive systems power critical processes in chemical processing, oil & gas terminals at the Port of Barcelona, water treatment facilities, and pharmaceutical formulation facilities.
Operations in European hazard zones require explosive atmosphere equipment to meet stringent safety metrics. Standard induction motors represent potential ignition sources due to high temperatures or electrical arcing. Our specialized low voltage motors integrate flameproof enclosures (Ex d/Ex de) to isolate electrical faults, mitigating risk in volatile Zone 1 and Zone 2 areas.

Bringing together a century of motor manufacturing expertise, featuring renowned industrial brands including ATB, Brook Crompton, Morley, Laurence Scott, Schorch, GE, and OLI.
Authorized global distributor of Wolong Electric Drive Group. Since its founding in 1984, Wolong has expanded to incorporate 3 global manufacturing bases, 39 individual production factories, and 3 high-tier R&D centers worldwide, driving technological innovation in hazardous-area motors.
Wolong's portfolio features acquired global motor manufacturing leaders: Austrian ATB Group (incorporating Morley mining motors and Laurence Scott low-starting-current naval/nuclear class equipment), and Germany's historic Schorch Electric (founded 1882), reinforcing industrial pedigree.
Supported by the integration of Brook Crompton Motors (over 100 years of efficiency designs) and a commercial/industrial motor partnership with General Electric (GE). This dual expertise in NEMA and IEC standards allows us to export certified equipment worldwide.
Optimized industrial performance designed to exceed strict safety regulations.
Engineered for Zone 1, Zone 2, Zone 21, and Zone 22 applications. Our products comply with European safety directives and offer reliable protection in gases, vapors, mist, and combustible dust environments.
Available in IE3, IE4, and ultra-high IE5 efficiency standards. Also offering Permanent Magnet (PM) motor layouts that reduce energy consumption and operating costs in continuous production plants.
A comprehensive product range that covers fractional-power to heavy industrial low voltage AC drives, variable frequency variants, tunnel boring machinery, and underground coal mine equipment.
Excellence in engineering, from high-strength cast frames to precision-wound VPI stator insulation systems.
The rotor features a durable squirrel-cage design, utilizing high-quality cast aluminum produced via centrifugal casting or advanced die-casting methods. The integrated rotor bars and end rings provide reliable mechanical and electrical performance. For larger or specialized capacities, copper bar rotors with high-strength brazed end rings are utilized to ensure operational stability under heavy startup loads.
Our stator insulation utilizes Class F and Class H materials. Coils are insulated with polyester-imide enameled wire, reinforced with mica tape and glass cloth, and processed through our Vacuum Pressure Impregnation (VPI) facility. This procedure eliminates air pockets within the windings, providing resistance against moisture, industrial chemicals, and thermal cycling stress.
The motor enclosure utilizes high-grade cast iron (or steel plates for custom configurations) designed through digital multi-physics thermal and structural simulations. The flameproof joints (paths) are machined to strict tolerances, allowing the enclosure to contain internal explosions without propagating flames to the surrounding atmosphere.
Our dynamic cooling layout features an optimized fan cover, internal air guide cylinders, protective mesh screens, and structural silencer plates. The non-sparking fan is paired with an aerodynamic air path that reduces operational noise while maintaining heat dissipation, even at low speeds under Variable Frequency Drive (VFD) operation.
Wolong drive systems hold comprehensive certifications, simplifying import and compliance clearance for Spanish and multinational industrial operators.
Our manufacturing facilities implement strict QA processes that align with ISO 9001 and ISO 14001 guidelines, maintaining consistency across our production batches.
Our products conform to standard IEC/EN 60079 series guidelines for explosion-proof safety, and are tested under NEMA standards for the North American market, including UL and CSA certificates. Crucially for coal mining export projects, our TESTSAFE compliance offers access to the Australian coal mining machinery supply chain, demonstrating the global versatility of our drive systems.
In modern industrial distribution, lead times and supply chain reliability are critical factors. Our manufacturing operations utilize a robust supply network and raw material sourcing, helping us maintain manufacturing continuity even during global shipping disruptions.
By consolidating operations in high-capacity hubs, we manage costs for key components—including copper wire, electrical steel, and cast frames—without compromising quality. We coordinate directly with major marine ports and European land transport routes, ensuring timely and cost-effective delivery to your site or warehouse in Barcelona.
Every low voltage explosion-proof motor undergoes inspection protocols before dispatch:
Tailored motor solutions for chemical, municipal, and marine operations across Catalonia.
Powering high-capacity pumps, compressors, and mixing equipment in chemical plants near Tarragona and Barcelona. Our Ex d designs contain internal sparks, protecting volatile gas environments (Group IIA, IIB, and IIC).
Compliance: Zone 1 & 2 Gas ProtectionConveyor drives, dust extraction fans, and grain silo machinery operating along the Barcelona harbor. Dust ignition-proof (Ex tb / Ex tc) motors protect against ignition risks from organic and metallic dust (Group III).
Compliance: Zone 21 & 22 Dust ProtectionReliable drives for aeration blowers and submersible sludge pump setups in municipal water treatment plants, where corrosive gases like hydrogen sulfide require high-durability epoxy finishes.
Compliance: IP66 High-Ingress EnclosuresA comprehensive selection of specialty flameproof motors for varied industrial environments.
Industrial regulations in the EU are driving toward increased energy efficiency and predictive maintenance integration. Our future technology roadmap focuses on three areas:
Reducing mechanical losses and maximizing energy savings in varying-speed operations.
Allowing real-time monitoring of ATEX-rated machinery without physical inspection penetrations.
Aligning with Spanish environmental guidelines to reduce lifecycle footprint during repair and recycling.
We modify shaft configurations, supply custom voltage taps (230V to 690V and intermediate frequencies), and construct matching motor skid frames to fit legacy foundations in Catalan refineries.
