Modular Explosion-proof Electrical Solutions for Corrosive Hazardous Areas
This set of explosion-proof electrical products has four main models for explosive and corrosive sites like petroleum, chemical, coal and ports. The control column works for on-site operation, master controller for commands, meter for power monitoring and switch for circuit conversion.
Modular design fits various production lines with high safety and practicality.
Customization for High-risk Area Explosion-proof Control Unit

We can customize housings made of cast aluminum, stainless steel and anti-corrosion resin to adapt to dry, humid, strong corrosive and other complex industrial working conditions in hazardous areas.

We provide multiple protection grades including IP54, IP55 and IP65, which fully meet diverse dustproof and waterproof requirements for both indoor and outdoor explosion-proof working sites.

Our products support IIA, IIB and IIC explosion-proof grades, which can match different types of flammable and explosive gas environments in various high-risk industrial workshops.

Customers can add meters, physical buttons and indicator lights as required, so as to freely combine different control and monitoring functional components for on-site use.
BZC Series Explosion-proof Operating Column
Tovent BZC series explosion-proof control column is core on-site control equipment for high-risk areas, manufactured in line with international explosion-proof standards. Its sturdy housing reaches IP65 protection grade for dust and water resistance, suitable for indoor and outdoor explosive gas and dust environments. With well-arranged internal parts and smooth operation, it realizes start, stop and adjustment functions. Impact-resistant and anti-aging, it runs stably long-term and serves petroleum, coal and chemical industries to guarantee on-site safety.


BZA8050-□ Series Explosion-proof Anti-corrosion Master Controller
BZA8050 master controller performs excellently in corrosive and explosive workshops filled with strong acid, alkali and volatile substances. Its special anti-corrosion housing resists chemical erosion and the integral explosion-proof structure passes multiple tests. The precise internal cam components work accurately without failure after repeated use. Adapting to T1-T6 temperature groups, it works all day long under harsh chemical working conditions.
BYB8050 Series Explosion-proof Anti-corrosion Ammeter
BYB8050 explosion-proof & anti-corrosion electric meter is designed for power monitoring in explosive and corrosive environments, displaying real-time voltage, current and energy consumption accurately. The clear dial ensures easy reading in dim light. The sealed explosion-proof structure blocks flammable gas and the anti-corrosion housing resists chemical erosion. Widely used in chemical plants, offshore platforms and gas stations, it is basic monitoring equipment for high-risk areas.


BZZ8050 Series Explosion-proof and Anti-corrosion Changeover Switch
BZZ8050 explosion-proof & anti-corrosion change-over switch has a wide voltage adaptation range for high and low voltage explosion-proof circuits with strong universality. Supporting multiple wiring methods, it connects with various explosion-proof control systems flexibly. Flexible installation includes cabinet embedding and wall mounting. Standardized parts facilitate maintenance and replacement. With high adaptability and stability, it is a widely used switching component in industrial explosion-proof circuits.
High-quality Certified Explosion-proof Control Devices for Coal & Mining Industry


Coal and mining industry belongs to high-risk explosion-proof fields, where electrical equipment must have strict safety certifications and super stable performance. Tovent’s four series of explosion-proof control and instrument electrical appliances are fully certified for mining application, adapting to underground tunnels, coal yards and dust explosion areas. The products feature anti-dust, anti-impact and anti-vibration design to fit the complex vibration environment of mining equipment. The control column realizes on-site equipment operation, the master controller manages remote commands, the electric meter monitors power consumption, and the change-over switch completes circuit conversion. The whole set of devices works coordinately to ensure the normal operation of mining electrical systems. We have standardized production workshops and complete quality inspection processes. All products are tracked throughout the whole life cycle to solve after-sales problems for mining users quickly.
