The newly developed EITEC-PROTEC modular systems will allow simplifications to virtually revolutionise the construction, assembly and also the servicing of flexible aluminium and steel lamella systems: after many years of work our engineers have succeeded in developing a multi-functional aluminium guide profile for universal use in machine construction. On the basis of this innovative profile, complete apron cover systems can be installed in far shorter times. Alternatively, steel lamella systems can be integrated. The EITEC-PROTEC system is simple, light-weight and technically elegant.
