Hazardous Area Equipment Protection
Run the equipment you need inside the zone, legally
Most of the equipment a classified area needs was never certified for it, and every gap surfaces at audit or at incident. Weidmüller Klippon® Protect certified enclosures, control stations and purged systems let plant operate and be maintained inside the zone without a shutdown or a de-classification argument.
How Equipment Gets Into the Zone
Certify it, pressurise it, or keep it out. There is no fourth option.
Use Equipment Certified for the Zone
Ex e, Ex i, Ex d, Ex n and Ex t rated enclosures, junction boxes, control stations and instruments, selected against the zone, gas group and temperature class on the classification drawing.
Purge What Cannot Be Certified
A purge and pressurisation system keeps the hazardous atmosphere out of the enclosure, allowing non-certified components inside a Zone 2 area, or Zone 2 certified components into Zone 1.
Certify the Assembly, Not Just the Parts
Populated enclosures and control stations are built and certified as complete assemblies to IECEx, ATEX and cULus, which is what the documentation at audit actually has to cover.
What Sites Get Out of It
The outcomes that matter on site.
Certification Evidence Ready at Audit
Every panel, station and system carries its IECEx documentation, no scrambling when the auditor asks.
Plant Keeps Running In-Zone
Purged enclosures and certified assemblies keep equipment operating and serviceable inside the zone instead of waiting on a shutdown.
Operators Control Plant Where They Stand
In-zone control stations remove the walk to the nearest safe area for routine starts and stops.
Existing Equipment Kept in Service
Re-classification does not have to mean replacement when pressurisation can protect what is already installed.
Which Zone Is the Equipment Going Into
Classification decides the protection method, and the protection method decides what can be installed. Find your zone before specifying anything.
Ex Protection Methods We Supply
Zone, gas group and temperature class are confirmed per project before equipment is specified. Send us the hazardous area classification drawing and we will match certification to it.
Two Decisions That Come Up Every Time
When purge is the right answer, and when a certified panel build is unavoidable.
When Ex p Is the Right Answer
Ex p keeps a positive internal pressure inside an enclosure so the hazardous atmosphere never reaches the equipment. It protects things that were never designed to be certified.
When You Need a Certified Assembly
An enclosure in a classified area is certified as a populated assembly, not as a collection of certified parts. That distinction is what audits turn on.
Weidmüller Klippon® Protect, certified enclosures, junction boxes and control stations
Klippon® Protect covers the approvals a classified area demands, ATEX, IECEx and cULus, across stainless steel, coated steel, GRP polyester and aluminium enclosures, Ex e and Ex i junction boxes, and Klippon® Control Stations with up to four control and indication elements. Enclosures are populated and certified as complete assemblies, so what arrives on site is the thing that carries the certificate.
Where This Application Matters Most
Anywhere an area has been declared a gas or dust zone.
