Introduction
Many industrial facilities operating today were designed years—or even decades—ago. While their core processes may still be efficient, the hazardous area equipment protecting these facilities often becomes outdated, non-compliant, or difficult to maintain. Changes in safety standards, aging infrastructure, and evolving operational demands make modernization essential.
Ex Industries (exindustries) provides specialized hazardous area retrofit and upgrade services, helping organizations modernize existing installations without the cost and downtime of full system replacement. By upgrading legacy systems with certified ex equipment, Ex Industries ensures compliance, improves safety, and extends asset life in explosive environments.
This article explains what hazardous area retrofit services involve, why they are critical, and how Ex Industries delivers safe, compliant, and cost-effective upgrade solutions across industries.
What Are Hazardous Area Retrofit & Upgrade Services?
Hazardous area retrofit and upgrade services focus on improving or replacing existing explosion-protection systems while keeping core infrastructure intact. Rather than dismantling entire electrical systems, targeted upgrades are applied to meet modern safety and compliance requirements.
These services typically include:
- Assessment of existing hazardous area installations
- Identification of compliance gaps (ATEX, IECEx, NEC, NEMA)
- Replacement of obsolete or damaged components
- Integration of modern certified ex equipment
- Documentation updates and compliance support
Ex Industries specializes in retrofitting systems using explosion proof enclosures, intrinsically safe barrier systems, explosion proof lighting, explosion proof cables, and precision accessories.

Why Retrofit Instead of Full Replacement?
Many facilities hesitate to modernize hazardous area systems due to perceived cost and downtime. Retrofit services offer a practical alternative.
Key Benefits of Retrofitting
- Reduced downtime compared to full system replacement
- Lower capital expenditure by reusing existing infrastructure
- Improved safety and compliance
- Extended equipment lifespan
- Compatibility with modern monitoring and control systems
Ex Industries designs retrofit solutions that minimize operational disruption while delivering maximum safety improvements.
Assessment & Hazardous Area Audits
Every retrofit project begins with a detailed assessment. Ex Industries supports hazardous area audits to evaluate existing installations.
Audit Scope Includes:
- Review of existing explosion proof enclosures and junction boxes
- Condition assessment of cables, glands, and accessories
- Verification of protection concepts (explosion proof, intrinsic safety, purge)
- Identification of obsolete or unsupported components
Audit findings guide the retrofit strategy, ensuring upgrades are both necessary and effective.
Upgrading Explosion Proof Enclosures & Electrical Boxes
One of the most common retrofit requirements involves outdated enclosures and electrical housings.
Retrofit Solutions Include:
- Replacement of aging explosion proof enclosures
- Upgrading explosion proof junction box assemblies
- Modernizing explosion proof electrical box installations
- Converting legacy systems to NEMA 7 enclosure standards
Ex Industries also supports compatibility with recognized brands such as adalet enclosures, appleton explosion proof boxes, and crouse hinds explosion proof boxes, making upgrades seamless.

Cable, Gland & Connection Upgrades
Electrical connections are often the weakest point in older hazardous area systems. Ex Industries provides targeted upgrades using certified components.
Connection Retrofit Services
- Replacement of degraded explosion proof cables
- Installation of modern hazardous location cable glands
- Integration of precision thread adapter solutions
- Use of certified adapters and reducers for compatibility
These upgrades restore enclosure integrity and prevent gas or dust ingress.

Intrinsic Safety System Modernization
Older facilities often rely on outdated control and instrumentation systems that no longer meet intrinsic safety requirements.
Intrinsic Safety Upgrade Services
- Replacement of obsolete barriers with modern intrinsically safe barrier systems
- Reconfiguration of instrumentation loops
- Integration with upgraded control panels
- Compliance alignment with current IECEx and ATEX standards
