Servicing your Seematz straightline window wipers

You can contact us with all your questions regarding spare parts, service and repair for your Seematz window wiper installation. We perform service jobs on Seematz window wiper installations onboard ships worldwide.

Refit of Seematz window wiper installation

After many years of service, even Seematz window wipers will eventually come to the point of refitting, due to the harsh conditions to which the wipers are exposed. As every window wiper installation is tailor made, and the execution of each installation is carefully filed including detailed measurement drawings, we can have your set of window wipers built again, exactly corresponding the original sizes and execution. That will normally take 8-10 weeks. After that, we can assist you with replacing the complete set of window wipers (or if you wish, only a part of it). Normally, the power supply, control panel and eventual wash installation can remain in place, thus reducing the impact of a refit both in time and costs. If your vessel is about to be in need of a window wiper exchange, just give us a call!
