The interior of the door closers incorporate a thermoconstant oil, designed to maintain the same closing speed and prevent the need for door adjustments in the event of abrupt temperature variations.
This ingenious element ensures stable and efficient operation, automatically adapting to environmental changes without compromising the integrity and safety of the door.

Door closers equipped with a hinged arm and retention offer the flexibility to hold the door open at the point of your choice.
These mechanisms allow the smooth passage of people in circumstances such as social events, meetings or simply when you want to encourage interaction and connection in a space.
In contrast, those that lack retention automatically close once their travel is complete.

The OTS73X models incorporate an innovative modular system to greatly facilitate the planning and installation of any application.
Components can be interchangeable for combination with all versions. The mounting plate is concealed and uniform according to EN 1154.

All models are easily installed, with adjustment valves located at faceplate to provide greater convenience during the process.
Complying with EN 1154 certification, the door closers have successfully passed more than 500,000 durability cycles and have obtained the highest classification for corrosion resistance, reaching grade 4 according to EN 1670.
