Engineered to comply with critical UL, CSA, ATEX, and IECEx directives for dangerous gas and dust environments in Boston Metro facilities.
The Greater Boston area and New England represent a highly sophisticated landscape of industrial process fields, environmental engineering facilities, utility hubs, and marine commerce. Operating high-voltage equipment in these regional settings demands compliance with rigorous fire-safety codes, local environmental guidelines, and NECA/OSHA safety expectations.
From the municipal water processing assets like the Deer Island Wastewater Treatment Plant to the LNG importing terminals around the Boston Harbor, process engineers demand explosion-proof systems that offer reliable mechanical outputs without sparking hazards. The regional growth in biotech manufacturing, chemical research, and hydrogen fuel cell development introduces Class I Division 1 and Division 2 atmospheres that need robust explosion protection.
WOLONG's portfolio of AC High Voltage Explosion-Proof Motors addresses these exact conditions, offering safety solutions, high thermal capacities, and resistance to environmental moisture and corrosive marine atmospheres.

A deep dive into our motors' structural engineering, designed for hazardous environments.
The rotor features a squirrel cage design with cast aluminum construction produced via centrifugal or die-casting techniques. This provides a single-piece construction that integrates rotor bars and end rings, ensuring reliable operation and starting torque. For larger capacities, copper bar rotors with reliable bar securing and end ring welding procedures are utilized.
The coil is crafted from polyester film reinforced with glass cloth, using low-powder mica tape with high mica content. Following the VPI (Vacuum Pressure Impregnation) process, the finished unit offers high dielectric strength, moisture resistance, and thermal stability under continuous loads.
Using digital platforms for structural and fluid multi-physics simulations, the frame uses high-strength cast iron or steel. This structure provides heat dissipation, mechanical shock resistance, and vibration margin, keeping the motor's operating temperature within safe margins.
Comprising a fan cover body, air guide cylinder, protective window, and silencer plate. The side-entry air inlet minimizes obstacles and limits noise propagation. Sound-absorbing materials lower the operating noise. Rated at IP22, the design prevents accidental physical contact.
Procuring HV explosion-proof motors from our advanced manufacturing bases in China offers clear economic and technical advantages:
Certified to operate globally, assuring safety, reliability, and regulatory alignment.
WOLONG has secured major product certifications, enabling it to meet the requirements of international markets. Our motors comply with key standards including ISO 9001 quality management, NEMA mechanical performance, and UL/CSA certificates for North American safety guidelines. For explosion protection, our products are certified to IECEx and ATEX standards, allowing safe installation in hazardous zones globally, including Europe, North America, and Australia.
Providing integrated drive solutions tailored for complex process machinery.
Our motors are matched with VFD systems (such as the YBBPX series) to provide step-less speed control, thermal stability, and protection against high harmonic loads.
Our TZYW and YZYKK positive-pressure type motors utilize housing purge systems that keep combustible dusts and gases out of the main motor frame.
Built with efficiency classes up to IE4 and IE5, these motors lower electricity consumption over decades of continuous processing operations.
