Dorma’s swing door compensates for varying wind conditions
Door technology specialist Dorma has launched two motorised swing door operators that are designed to compensate for varying wind conditions. Two versions are available, the ED100A that is capable of operating doors with a weight up to 100kg and 1100mm wide, and the ED250A, which can operate doors with a weight up to 250kg and 1600mm wide. The doors have wind load control that recognises and compensates for wind loads of up to 150N. The system is compatible with infrared safety sensors and has an energy saving mode that the company says reduces energy use by up to 30% compared with previous Dorma systems.
