The new generation of KAISER fire protection boxes combine all the features of the HWD 68 and HWD 90. In addition, they cover all possible applications that occur in practice with the conduit entries. Thanks to the evaluated AFS technology, the HWD 68+ also guarantees a fire resistance duration of F30-F90 or EI30-EI90. The HWD 68+ also fulfils the F30-B-F90-B fire resistance duration in timber frame and timber panel construction as well as in cross-laminated timber construction. The HWD 68+ enables almost unrestricted and universal electrical installation in fire protection walls.
