Explosion-proof sealant for cable trays in Democratic Republic of Congo

Certified explosion-proof sealants for cable trays include Roxtec Ex seals, Astro 6804 epoxy, AF BAGS fireproof pillows, and NOFIRNO silicone systems, all suitable for hazardous areas.

ATEX and IEC

Ex Certified Cable Seals

Roxtec Ex cable transit devices are designed for use in potentially explosive atmospheres and are certified under ATEX and IECEx standards. They provide protection for Ex e (increased safety for gas) and Ex tb (protection by enclosure for dust) rated enclosures, including transformers, motors, generators, and junction boxes. These seals are suitable for Zone 1 and 2 gas areas and Zone 21 and 22 dust areas, making them ideal for industrial facilities in the DRC with hazardous atmospheres.

Fireproof Pillows for Cable Tray PenetrationsAF BAGS are intumescent and ablative fireproof pillows certified under EN 1366-3, capable of sealing cable tray penetrations up to EI 240. They are designed for cables up to 21 mm in diameter and can be inserted into thin structures without additional framing. These pillows are repositionable, non-toxic, and facilitate maintenance or modification of cable systems.

Explosion-

Proof Epoxy Sealants

Astro 6804 Liquid Epoxy Sealing Compound is a two-component, flame-retardant epoxy suitable for potting cable glands and bushings in explosion-proof enclosures. It offers void-free encapsulation, fast curing, UL 94V-0 flame resistance, and UL 2225 certification for high explosion-risk applications. Its flowable viscosity ensures complete sealing, and it is VOC-free, making it suitable for field applications in oil, gas, and mining operations.

Multi-

Purpose Silicone Seal Systems

The NOFIRNO system provides a long-term, maintenance-free solution for sealing cable and pipe penetrations. Made from high-grade silicone, it is approved for fire, watertight, gas-tight, blast, and shock applications, and can accommodate metallic, GRP, or plastic pipes. Its adhesion-based design prevents damage to sensitive cables and ensures durability in harsh industrial environments.

Selection Considerations

When choosing a sealant for cable trays in the DRC: Hazard classification: Determine the zone (gas or dust) to select the appropriate ATEX/IECEx rated product. Cable size and tray dimensions: Ensure the sealant or pillow fits the cable diameter and tray width. Fire and chemical resistance: Consider products with high EI ratings or chemical resistance for industrial environments.

Ease of installation and maintenance: Repositionable or flowable sealants facilitate future modifications. These products are widely used in mining, oil & gas, and chemical processing industries, making them suitable for deployment in the Democratic Republic of Congo.
