The system remains operative in the face of multiple adverse scenes. It has an invulnerable system of anti-vandalism security

Automatic control

It It is operated, remotely or in-situ, activating the electrical, hydraulic or manual nitrogen circuit. The opening is in 20 seconds.


It resists a weight of up to 6 tons above its surface, which makes it very safe in case of external blocking.


The centralized management from the control center minimizes maintenance costs.


Anti-vandal safety: The door is almost impenetrable from the outside to prevent misuse and intentional damage.
Normal interior-exterior hydraulic (non-electrical) open-close function.

Includes a supplementary hydraulic system to the electrical system which ensures that the opening system works in even the most extreme conditions (motor or electrical panel breakdown).

Emergency interior-exterior opening function (safety backup cell): Addition of a second propulsion system connected to the general hydraulic circuit that is activated in the event the electrical propulsion system cannot work. The energy is stored in a waterproof oil/pneumatic tank (no refill required) that contains N2 as the propelling element to drive the oil of the hydraulic circuit and enable up to four manoeuvres.

Interior emergency opening function (manual pump 45 cc/cylinder):

A manual pump is also proposed as a recovery system. With a manual 45 cc/cylinder pump, the largest on the market, the system can be opened in two minutes with around 80 piston strokes.
Thrust force: 6,234 kg to 100 bar (2x3117 kg).
Two hydraulic cylinders with 600 mm stroke.
Normal operation time: 40 seconds to open.
Emergency operation time: 20 seconds (adjustable).

Recovery circuit:
The recovery circuit has a cycle switching valve which allows the door to be closed by pushing a hydraulic switch inside the unit in the event of an emergency system malfunction.

Control system: The control system uses an automaton which enables the system parameters to be monitored using a SCADA application.
