Safety Features Explained

Our commiment to the world's safest high-speed door systems.

Efaflex are at the forefront of designing the safest industrial doors on the market today. In 1998 Efaflex introduced the world to its proprietary safety system, the TLG light gate. With over 45 years experience in developing the most up to date safety features, we at GEA Automation are of the opinion that Efaflex produces the safest and most reliable industrial door systems available today.

Countertension explained

The door leaf counterbalance is a back-pull mechanism: Tension springs are installed in the side frames. The tension springs are connected to the synchronous shaft by heavy-duty belts. The tension springs are tensioned when the door system is closed, and relaxed when the door system is open.

This way the door system can also be opened by hand (without electrical power) in case of emergencies. In normal mode, the motor is assisted by the force of the tension springs. The spring tension is calculated for each individual door - as standard - depending on the door type.

Minimum safety requirement: As adhering to EU Standards* (See standards and directives below)

Safety Edge

Efafex safety edges are designed to guard against any possible shearing or crushing points on Efaflex High Speed Doors. They are to be used on doors where there is any movement and risk of crushing.

Safety edges are a rubber profile with a contact strip in the middle which triggers an automatic stop when the contact strip detects any contact.

The rubber of the safety edge compresses, providing protection for people and objects from crushing.


Infared Photocells on 1 or 2 points of an EFAFLEX high speed door will stop the door and return it to the up position when either beam is broken, this is an effective safety feature at a standard height of 300mm from the ground, this is a customisable feature relative to the clients needs.


With absolute safety

In order to avoid crashes in the lower area of the door, where nearly 90% of all crashes happen, right from the beginning, you are on the safe side by using our TÜV-certified infrared light grid EFA-TLG®. The system is unique worldwide and it is completely self-monitoring. It is directly installed into the lateral door tracks so that it is well protected. EFA-TLG® monitors the closing plane of the door up to a height of 2.5 metres. Crossing infrared rays generate a nearly flat light grid which can detect even the smallest obstacles without contacting them. If there is something in the way, the closing movement is stopped immediately or not initiated at all, respectively. This unique door technology protects persons, doors, vehicles and material.
