In the world of explosion proof electrical equipment, ensuring circuit safety in hazardous areas is essential. That’s where Ex Industries stands out — as a global leader in providing high-performance Safety Barriers, Intrinsic Safety Barriers, and Isolation Barriers designed for Ex Zones, Class 1 Division 1 Enclosures, and ATEX Certified Enclosures.
Our advanced barrier electrical systems protect personnel, equipment, and infrastructure in explosive atmospheres by limiting energy transfer — guaranteeing safe operation even in the most demanding industrial environments.
What Are Safety Barriers?
Safety Barriers are electrical protection devices that prevent excessive voltage or current from passing into hazardous locations, where flammable gases or vapors may be present.
At Ex Industries, our intrinsic safety barriers, zener barriers, and isolation barriers form the foundation of safe electrical circuit design in hazardous area enclosures.
They ensure that even if a fault occurs in non-hazardous zones, it cannot produce sparks, arcs, or excessive heat that could ignite an explosion.
These barriers are essential components in intrinsically safe circuits, commonly used in ex equipment, ex proof enclosure systems, and explosion proof cable glands configurations.
How Safety Barriers Work
Intrinsic safety barriers work by controlling and limiting the electrical energy allowed into hazardous areas.
There are three main types used by Ex Industries customers:
- Zener Barriers – Simple, cost-effective barriers using zener diodes, resistors, and fuses to shunt excess energy safely to ground.
- Isolation Barriers – Advanced electronic barriers using galvanic isolation to separate safe and hazardous circuits while maintaining signal integrity.
- Intrinsic Safety Barriers – Certified devices that maintain intrinsic safety (IS) standards, ensuring no spark or thermal event can occur.
These barrier types are crucial in connecting field instruments, sensors, and control panels inside hazardous location enclosures while maintaining system certification under ATEX, IECEx, and UL/CSA standards.
Applications of Safety Barriers
Ex Industries Safety Barriers are used across multiple industries that demand hazardous area solutions:
- Oil & Gas refineries
- Chemical processing facilities
- Mining and Marine industries
- Power generation plants
- Pharmaceutical production
- Food and beverage manufacturing
In each environment, ex proof junction box, explosion proof enclosures, and hazardous location cable glands are paired with intrinsically safe barriers for total circuit protection.
