In public buildings doors are often not only very large, they are also exposed to particularly high loads. A strong and reliable electromotive door closer is therefore essential in facilities such as hospitals, schools, commercial offices, aged care facilities or kindergartens. With the new ETS 73, Allegion now has an electromotive door closer in their range that is specifically tailored to these challenges while also assisting with fire protection.
Large, heavy doors in public buildings are the exception rather than the rule, and at the same time doors are often used hundreds or even thousands of times a day. They must also ensure easy access for those who may not have the strength to open heavy commercial doors manually.
The electric motor drive unit of the door closer ETS 73 provides a powerful solution for these situations. It is particularly strong, allowing the almost silent opening and closing of doors up to 250 kilograms and a width of 1.6 metres. It can carry these loads smoothly in winds that are up to Gale Force 9 thanks to motorised wind load regulation.
However, not all doors of a building are equally busy. For example, a home entrance is used less frequently than an office door and the ETS 73 has a setting for this situation. Using Full Power, the door opens quickly and automatically with the help of a safety sensor which permanently monitors movement in the area. In the case of an office door, this is usually not necessary. Here, the sensor can be dispensed with by selecting Low Power mode. This setting is also more energy-efficient.
