Design Software

DEHNplan, the quick way to standard-compliant external lightning protection.
With just one tool, you can easily plan standard-compliant external lightning protection for your project.

The BIM-enabled software for engineering offices, planning engineers and lightning protection installers facilitates your planning by visualizing the protected volume and separation distances and by providing an automatic bill of materials. Regular updates keep the system permanently up to date. You do not need any special prior knowledge to use DEHNplan: your expertise in lightning protection and earthing, as well as CAD knowledge, are the most important prerequisites for using DEHNplan optimally and efficiently.
