When safety, performance, and reliability are critical, Ex Industries stands at the forefront of explosion-proof enclosure manufacturing. Designed for hazardous locations, our Class I, Division 1 Enclosures and Class II, Division 1 Enclosures provide robust protection against ignition, corrosion, and environmental damage — ensuring safe electrical operation in the world’s most demanding industrial environments.
From offshore oil rigs to chemical processing plants, our explosion proof enclosures and flameproof housings are trusted by engineers and safety professionals worldwide.
What Are Explosion-Proof Enclosures?
Explosion-proof enclosures (sometimes called flameproof enclosures) are heavy-duty junction boxes designed to contain internal explosions caused by electrical faults, arcs, or sparks.
In hazardous areas where flammable gases, vapors, or dust are present, these enclosures prevent internal explosions from spreading to the surrounding atmosphere — protecting both personnel and infrastructure.
Each Ex Industries enclosure is engineered to perfection — combining durable materials, precision-machined threads, and advanced sealing technology to deliver maximum safety.
Built for Class I and Class II Hazardous Locations
Ex Industries manufactures enclosures for both Class I, Division 1 (gas) and Class II, Division 1 (dust) environments — meeting or exceeding all ATEX, IECEx, UL, and CSA certification standards.
Class I, Division 1 Enclosures:
Designed for facilities where flammable gases or vapors are present under normal operation — such as oil refineries, gas plants, and offshore platforms.
Class II, Division 1 Enclosures:
Built for areas with combustible dust (such as metal, grain, or chemical dust) in normal operating conditions — common in pharmaceutical, food processing, and mining industries.
With Ex Industries, you get enclosures that are certified, reliable, and built to perform — even under the harshest environmental conditions.
How Explosion-Proof Enclosures Work
An explosion proof enclosure works by safely containing any explosion that might occur inside.
If a spark ignites gas or dust inside the box, the pressure and heat of the explosion are contained within the enclosure body. Specially designed flame paths allow gases to escape slowly and cool before reaching the outside air — preventing ignition of the external atmosphere.
That’s why Ex Industries uses precisely machined joints, reinforced walls, and high-strength materials in every product.
Precision Engineering for Maximum Safety
Every Ex Industries enclosure undergoes strict quality control and performance testing.
Key features include:
- Flameproof (Ex d) construction for high-risk areas
- Ingress Protection (IP66/IP67) for water, dust, and debris resistance
- Corrosion-resistant stainless steel or aluminum housing
- Custom drilling and tapping for ex proof cable glands, thread adapters, and reducers
- Temperature and pressure tested for long-term durability
Our engineering team ensures that each product delivers absolute safety in line with IEC/EN 60079-1 and UL 1203 standards.

Wherever there is risk, Ex Industries provides protection that performs.
Explosion-Proof vs. Flameproof Enclosures
While often used interchangeably, there’s a technical difference between explosion-proof and flameproof designs:
Explosion-Proof Enclosures are typically built to UL/NEMA standards for the U.S. and Canada, rated for Class I, Division 1 hazardous locations.
Flameproof (Ex d) Enclosures meet IEC/ATEX standards used internationally, offering equivalent protection for Zone 1 and Zone 2 hazardous areas.
At Ex Industries, we manufacture both — ensuring you get the right solution, no matter where your operation is located.
Standards & Certifications
Our enclosures are fully certified and compliant with global hazardous area standards:
- ATEX Directive (94/9/EC) – European compliance for explosive atmospheres
- IECEx Certification – Global acceptance for explosion protection
- UL & CSA Listed – North American approval
- EN 60529 (IP Ratings) – Dust and water ingress protection
- NEMA Ratings (4X, 7, 9) – Corrosion and moisture resistance
- EN 60079 Series – Intrinsically safe, flameproof, and increased safety standards
When you install Ex Industries enclosures, you’re guaranteed certified performance — no compromises.
