BXK51 is a standard Class IIB explosion-proof control box with modular circuits. It fits fine chemical and food fermentation workshops with stable and reliable equipment control performance.Carbon steel and stainless steel shells are optional. The wall-mounted box saves space. The optimized sealing structure stops volatile gas from damaging internal electrical components.Ammeters, voltmeters and surge protectors are optional for circuit monitoring. The simple operation panel allows on-site staff to use the device quickly.
BXX51 Explosion-proof Power Maintenance Box
BXX51 integrates power distribution, protection and sockets for high-power maintenance equipment. The built-in circuit breaker cuts power automatically with high safety performance. It supports both steel pipe and cable wiring to match existing pipelines. Spacious interior and neat wiring facilitate daily circuit inspection for workers.Widely used in metallurgy, hazardous waste treatment and coastal chemical industries. The optimized circuit provides stable power output for heavy-duty maintenance equipment.


Explosion-proof Lighting & Power Distribution Box
This box separates lighting circuits and power circuits completely. As core distribution equipment, it provides integrated power supply for chemical, coal and military factories.Die-cast aluminum alloy shell with electrostatic spraying is rust-proof and impact-resistant. Optional IP54/IP65 grades suit both indoor workshops and outdoor equipment areas.Equipped with high-break circuit breakers and motor protectors, it prevents accidents. The explosion-proof structure meets standards for Zone 1 and Zone 2 gas hazardous areas.
Explosion-proof Power Distribution Box
This general explosion-proof box distributes power centrally for hazardous areas with complete circuit protection. Compact and flexible to install in workshops, warehouses and drilling sites.It fits both explosive gas and combustible dust environments with excellent dustproof sealing. Ideal for rubber plants, fireworks factories and chemical warehouses.Designed for mobile drilling rigs and temporary production lines, it supplies stable power and resists vibration. Firm ports avoid loose wires during equipment movement.


BXK52 Explosion-proof Electrical Control Box (IIC)
BXK52 is a high-grade Class IIC explosion-proof control box with strict standards. It is specially used for high-risk gas areas such as hydrogen and acetylene workshops.The reinforced flameproof structure with precisely calculated gaps blocks ignition paths. The sturdy shell has better impact resistance than ordinary explosion-proof boxes.
Application Fields & Scenario


Onshore oilfields: Distribute power and control pumping units in sandy area;Offshore Platforms: Supply power for maitence under salt fog.
Oil & gas tanks: Power lights/monitors with reliable circuit protection;Distillation areas: Separate power circuits for power and lighting loads.
Chemical warehouses: Power distribution and maintenance power for patrol tools;Labs: Control instruments/supply power for test device.
Coal washing plants: Protect circuits in coal dust hazardous areas;Open pits: All-weather power supply for open mining equipment.
Gas zones: Special explosion-proof boxes for methane environments;Smelting workshops: High-temperature resistant power for furnaces.
Explosive gases are divided into different risk levels, so matched explosion-proof equipment is necessary. Tovent BXK51 (IIB) and BXK52 (IIC) control boxes target low and high-risk gas environments respectively. BXK51 is cost-effective for fine chemical and food fermentation workshops. BXK52 adopts enhanced explosion-proof structure for hydrogen and acetylene workshops. Both use modular design for easy component replacement and circuit adjustment. They have good heat dissipation and sealing performance, running steadily for a long time in complex industrial environments.
Most flammable and explosive factories need independent power supply for lighting and production equipment. Tovent explosion-proof lighting and power distribution boxes separate lighting circuits and power circuits scientifically to avoid mutual interference. The built-in overload and short-circuit protectors can prevent electrical accidents effectively. The box shell is anti-collision and durable, suitable for indoor workshops and semi-outdoor equipment areas. Modular internal structure allows users to add circuits later. It has become the mainstream power distribution device for pharmaceutical, printing and dyeing and chemical enterprises.
