Abstract[English]
An entrance system (1) has a movable barrier element (40) positionable to close off and open up, respectively, a passage between different temperature zones. A direct heating arrangement (50) that comprises one or more heating elements (51) is provided in a vicinity of a surface of the movable barrier element (40). The direct heating arrangement (50) is configured for generating heat locally at one or more areas of the movable barrier element (40) susceptible of ice build-up, thereby preventing or mitigating such ice build-up.[French]
Un système d'entrée (1) comprend un élément barrière mobile (40) pouvant être positionné respectivement pour fermer et ouvrir un passage entre différentes zones de température. Un agencement de chauffage direct (50) qui comprend un ou plusieurs éléments chauffants (51) est disposé à proximité d'une surface de l'élément barrière mobile (40). L'agencement de chauffage direct (50) est conçu pour générer de la chaleur localement au niveau d'une ou de plusieurs zones de l'élément barrière mobile (40) sensibles à l'accumulation de glace, ce qui permet d'empêcher ou d'atténuer une telle accumulation de glace.
