Our direct current (DC) motors mean smooth operation of garage doors, allowing for quiet, more energy efficient motion. Digital intelligence systems make it possible for Marantec openers to learn as they work, using the optimal force required to open and close the garage door without jerking or slamming. This feature not only improves safety and saves energy, it also prolongs the life of the entire garage door system.
