For decades, the name DEHNventil has been synonymous with powerful and reliable lightning and surge protection. Since its debut in 1983, this robust device has stood the test of time in demanding electrical environments. Now, DEHN is proud to unveil the next evolution: a newly designed DEHNventil that delivers the same trusted performance in a slimmer, more compact package – half the width, double the convenience.
The new DEHNventil is a combined type 1+2+3 arrester as per the EN 61643-11 standard. It comes in a single compact module that is just four standard DIN modules wide – saving up to 50% of the space compared to the previous generation and many other market alternatives. This smaller footprint provides valuable space in the switchgear cabinet, allowing for easier installation, future expansion, or even the use of a smaller and more economical cabinet. For contractors and panel builders, this translates directly into cost and time savings.
What hasn’t changed is the performance. The new DEHNventil maintains its superior surge protection capabilities with a follow current extinguishing capacity of up to 100 kA rms and exceptionally low residual energy, made possible by DEHN’s integrated RAC spark gap technology. This ensures comprehensive protection for terminal equipment, especially within a 10 m radius of the cable length.
DEHN has also added user-friendly enhancements that make this version even more compelling. The updated design includes a remote signalling contact, enabling 24/7 system monitoring. This feature allows for predictive maintenance and more efficient deployment of service resources, ultimately reducing downtime and maintenance costs.
Additionally, the DEHNventil has been tested for vibration and shock resistance, making it a reliable choice even in environments with mechanical stress. It’s ideal for critical infrastructure, industrial applications, and any installation where reliability is non-negotiable.
Another standout advantage is its single-module construction. Unlike multi-part arresters that may require replacement of individual components, the DEHNventil ensures that once replaced, all protection modes are fully operational again – no partial protection, no guesswork. This not only increases safety but also extends maintenance intervals and simplifies servicing.
In many installations, just a few centimetres of cabinet space can mean the difference between fitting a new component or needing an entirely larger cabinet. The space-saving benefits of the new DEHNventil can lead to real savings on both material and installation costs.
To sum it up, the new DEHNventil is more than just a redesign – it’s a smarter, more efficient, and more powerful way to protect electrical systems from lightning and surge events. With its combination of compact size, full-spectrum protection, and ease of use, it sets a new benchmark in surge protection technology.
