Ex-p pressurized panels designed and supplied. ATEX safety certified.
Maximum Safety in Explosive Atmospheres: Tailored Solutions for Zones 1, 2, 21, and 22. The design of pressurized electrical panels (Ex p protection type) represents the most technologically advanced solution for installing standard industrial components in hazardous areas. Thanks to internal overpressure, our panels guarantee complete segregation of ignition sources, ensuring compliance with the ATEX Directive 2014/34/EU and IECEx standards.
- THE ADVANTAGES OF PRESSURIZATION in enclosures or enclosures
- Why choose a pressurized enclosure over an explosion-proof (Ex d) solution?
- Cost Reduction: Use of standard components (inverter, PLC, touch panel) inside the enclosure, eliminating the need for costly individual certifications for each component.
- Lightness and Flexibility: AISI 316L stainless steel or aluminum enclosures are much lighter and easier to install than heavy cast iron Ex d enclosures.
- Optimal Heat Dissipation: The flushing cycle and pressure maintenance promote heat exchange, ideal for high-power equipment.
- Simplified Maintenance: Quick access to internal components via hinged doors, eliminating the dozens of screws typical of explosion-proof enclosures.

1. What is the difference between an Ex p and an Ex d
enclosure?
While the Ex d (explosion-proof) type of protection contains
the explosion inside a very heavy and robust enclosure, the Ex p
(pressurization) type prevents the explosive atmosphere from entering the
enclosure. This allows the use of lighter stainless steel enclosures and
standard industrial components, dramatically reducing weight and maintenance
costs.
2. Can I install a standard inverter in a pressurized
enclosure?Yes, this is one of the major advantages of Ex p protection.
Non-ATEX-certified components (such as inverters, PLCs, or industrial PCs) can
be installed inside a certified pressurized enclosure, since the purging system
with clean air or inert gas eliminates any risk of ignition before power-up.3. What happens if pressure is lost inside the enclosure?
The IEC 60079-2 standard provides for redundant safety
systems. In the event of a loss of overpressure below the minimum limit, the
control system immediately activates an alarm or disconnects the power supply,
depending on the zone classification (Zone 1 or Zone 2) and the risk
assessment.4. In which ATEX zones can Ex p panels be installed?
Pressurized panels are suitable for installation in Zones 1 and 2 (for gases) and Zones 21 and 22 (for dust). Depending on the required level of protection (pxb, pyb, or pzc), they guarantee maximum safety even in the constant or occasional presence of explosive atmospheres.
5. What certifications must accompany a pressurized panel?
Each panel must be supplied with the CE marking and the Ex symbol, accompanied by the Declaration of Conformity to ATEX Directive 2014/34/EU. It is also essential that the technical file include the pressurization system certificate and the final inspection of the complete panel.
