Requested a quote for the ATEX junction box for a Zone 1 installation at a chemical plant. Needs delivery timeline and IP66 test report.
What our clients say about our explosion protection solutions
Our clients rely on CanineSafety for dust-tight junction boxes and zener barriers that perform under pressure. Every unit is pressure-tested and flamepath-verified before shipment.
The ATEX junction boxes we ordered for our solvent recovery unit arrived with full certification docs. Installation was straightforward, and the IP66 rating has held up through monsoon season.
We replaced our old terminal boxes with CanineSafety’s blast-resistant enclosures. The pressure relief panels are a game-changer for our hydrogen vent area. No more shutdowns from false alarms.
The intrinsic safety zener barriers we installed on our 4-20 mA loops have eliminated nuisance trips. The compact DIN-rail design saved us 30% cabinet space compared to the previous brand.
Dust-tight junction boxes from CanineSafety passed our internal audit with zero non-conformances. The silicone gaskets and stainless steel construction are exactly what we need for Zone 21 areas.
We needed explosion-proof enclosures that could withstand salt spray and vibration. CanineSafety delivered custom units with 316L steel and bonded grounding. Two years in, no corrosion issues.
Clear answers about ATEX enclosures, zener barriers, and blast-resistant systems for hazardous areas.
Our ATEX-certified junction boxes are approved for Zone 1, 2, 21, and 22 areas. They are built with 316L stainless steel, IP66 ingress protection, and flameproof joints that meet EN 60079-1 requirements. Each unit is pressure-tested and flamepath-verified before shipment.
A zener barrier limits the electrical energy that can reach a sensor or transmitter in a hazardous zone. It uses precision zener diodes and current-limiting resistors to keep voltage and current below ignition levels. Our modules are ATEX and IECEx certified, available for 4-20 mA loops, thermocouples, RTDs, and digital I/O signals.
Yes. Our blast-resistant electrical enclosure system is designed for installations where internal arcing or gas ignition may occur, including hydrogen stations and battery energy storage. It features reinforced steel construction, explosion-relief panels, and bonded grounding. The design complies with NFPA 496 and EN 60079-2 standards.
We offer multiple cable entry configurations including metric and NPT threaded entries, compression glands, and blanking plates. All entries are certified for flameproof sealing. Custom entry layouts can be specified at the time of ordering to match your installation requirements.
Absolutely. Every enclosure and barrier ships with a full documentation package including the ATEX certificate of conformity, IECEx certificate, test reports for pressure and flamepath verification, and a declaration of incorporation. We also maintain traceability records for each serialized unit.
Understanding our scope and limitations
Our ATEX-certified enclosures are tested and marked for use in gas Groups IIA, IIB, and IIC, and dust Groups IIIA, IIIB, and IIIC. Certification applies strictly to the enclosure assembly as supplied — any field modification, such as drilling additional entries or replacing cable glands with non-certified parts, voids the certification and shifts responsibility to the installer.
Zener barriers are passive devices that require a separate, certified earth connection to function correctly. They work with 4–20 mA loops, thermocouples, RTDs, and digital I/O, but are not recommended for high-frequency signals or circuits where the loop resistance exceeds the barrier’s specified maximum. Always verify the barrier’s voltage and current ratings against your instrument’s operating range before installation.
Each blast-resistant enclosure is hydrostatically tested to 1.5 times its rated pressure. The rated pressure is determined by the client’s process hazard analysis and is stated on the nameplate. Standard ratings range from 10 psi to 50 psi internal overpressure. The pressure relief panels are designed to open at a set threshold, venting gases in a predetermined direction — this does not mean the enclosure is sealed after a blast event.
We supply and deliver the equipment with full documentation, but we do not perform on-site installation or commissioning. Our team can provide remote technical support during installation, and we recommend engaging a certified electrical contractor familiar with hazardous area practices. Any damage caused during installation is not covered under warranty.
Standard junction boxes ship within 10 working days. Custom configurations — such as non-standard cable entry patterns, special mounting brackets, or bespoke internal terminal layouts — require 4 to 6 weeks from approval of the engineering drawing. Rush orders are possible with a 30% surcharge and subject to material availability.
