Discreet and energy-efficient air curtain for revolving doors.
Rotto is a customized air curtain installed above your revolving door, with the exhaust duct adapted to the diameter of the door. The air curtain is equipped with energy-efficient EC motors which enable stepless control of the airflow. Together with the intelligent FC control system, the air curtain allows you to easily optimize your comfort and save energy.
This model of air curtain blows warm air downwards to the front of the opening of the revolving door. This warm air stream is heating the inside air down to the bottom and shields it from cold outside air. The duct with the aluminium blow out vanes matches the door radius.
