Thanks to the integrated SoftSystem closing mechanism, Liebherr appliance doors close automatically from an opening angle of about 30°. SoftSystem promises gentle closure even when the door shelves are fully stocked. In the home, refrigerator doors are opened several times a day and have to be capable of withstanding high loads and so, when testing them, we simulate over 100,000 door-opening movements to ensure that all components have a long service life.
