They reach 19 metres high – the interception rod of the irod system by OBO. The flexible system protects extremely sensitive biogas plants as reliably as free-standing PV systems or installations in potentially explosive areas against direct lightning strikes. The benefit of irod: There is no need for shovel or digger to move the earth and no concrete foundation needs to be poured.Solid concrete feet, each weighing 16 kg, give both the interception rods and the stands sufficient support. During installation, it is very easy to align the threaded rods. Thanks to these features, irod is ideally suited for the installation in already existing systems.
