Ensures automatic closing of the doors.

OTS Series

The hydraulic door closer ensures a smooth and effective automatic closing of the doors, preventing slamming doors. It is ideal for doors with high traffic and allows you to regulate the speed and power of the closing. There are models with a retention option, which allows you to keep the door open if desired.

OTS Series Instructions

Energy savings

Door closers offer significant energy-saving benefits. These devices play an essential role in preventing energy waste by regulating the automatic closing of doors, preventing them from remaining open unnecessarily.

In addition to contributing to safety, door closers are key to maintaining a constant room temperature, avoiding heat or cold losses generated by air conditioning. This efficient temperature control translates into a significant reduction in the costs associated with energy consumption in buildings.

Most relevant characteristics

Thermometric valves

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.

Retention mechanism

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.

Modular system

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.

Durability

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.
