Door Closer VTS 73x FL
With the concealed door closers VTS 73x FL, you can make your fire doors particularly smooth-running and barrier-free. The integrated electric free swing function enables the door to be opened almost freely – almost as if no door closer were installed. At the same time, the system ensures safe and reliable closing of the door in the event of fire. The VTS 73x FL door closers, concealed in the door leaf, give your doors an elegant and modern appearance: closer and guide rail are invisible when the door is closed, so the design of your architecture remains in clear focus.

Standards and safety requirements
Our concealed door closers VTS 73x meet the highest standards: they are ideal for barrier-free construction according to DIN SPEC 1104 and DIN 18040, approved for fire doors and tested according to EN 1154, EN 1155 and EN 1158 – for maximum safety and comfort.
door closing device with controlled closing sequence
DIN EN 1154 refers to door closing devices with controlled closing action. This standard specifies the requirements and test methods for door closers used on swing doors to ensure that they can reliably close again after opening. The classification of door closers according to this standard is based on criteria such as application class, durability, door closer size, and suitability for fire and smoke protection doors.
Electrically operated hold-open devices for turn-leaf doors
The standard EN 1155 refers to electrically operated hold-open devices for Turn-Only doors. These devices allow doors to be held in an open position and to close automatically when required, for example in the event of fire or smoke. The standard defines the requirements and test methods for these devices to ensure their functionality and safety.
Closing sequence controller – requirements and test method
The EN 1158 standard refers to closing sequence controllers for double-leaf hinged doors. These controllers ensure that the two door leaves close in the correct order to provide effective sealing, especially for fire and smoke protection doors. The standard specifies test requirements and conditions and covers both separately mounted closing sequence controllers and those integrated into the door closer, which may be equipped with electrically operated hold-open devices.
barrier-free construction
The DIN 18040 standard deals with the planning principles for barrier-free construction. It is divided into different parts that cover various aspects of construction to enable people with disabilities, elderly persons, and children to participate equally in everyday life. An important aspect of this standard is the easy opening of doors without external assistance. In this context, requirements are placed on door closers, such as limiting the operating forces to ensure that doors are easily accessible.
Door hardware for use by children, elderly and disabled persons in private and public buildings
DIN SPEC 1104 aims to enable effortless passage through doors, especially for children, elderly people, and persons with disabilities. It recommends the use of manually operated closing devices with a sharply decreasing opening moment. This means that the force required to open the door is reduced by about 40 percent in the range from 2 degrees to 60 degrees of door opening. This specification thus supports barrier-free access in accordance with the principles of universal design.
