In Norway, many places can only be reached by water - accordingly, people often move from place to place by ship. The automatic doors in particular are exposed to extraordinary stresses: strong winds, high humidity, heavy swell, freezing temperatures and, last but not least, salty splash water. A case for Gilgen: Accordingly, our Norwegian sales partner Bjelland Automatic AS equips the fast boats of Nordland County Municipality Transport with encapsulated FD20 swing door drive units - they are installed in a specially developed steel housing and thus perfectly protected. Of course, the cabling passages and linkage axles are also waterproof. Access to the drive controls is ensured via an inspection hatch on the housing. One of the advantages is that the integration of the Gilgen pheripheral components does not differ from a conventional FD20 drive.
