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.

• With no direct connection between the inside and outside air, optimal inside climatic conditions are achieved.
• When the door revolves cold air is entrained with the door wing and the difference in temperature between outside and inside air results in a cold zone directly behind the door.
• For heating the incoming air and air curtain is to be installed directly behind or inside the revolving door which leads to pleasurable climatic conditions, in the entrance area.
