Roller Shutters Protection Without box
The PEI Rolling Shutters without Box are unique in their design and customisation for the user. The reliability of Rolling Protection without Box guarantees up to 1,000,000 movements, thanks to the return motor equipped with multiple springs, which is reliable and operates with very high forward speed.

Mechanism
SURE-SPRING®
SURE-SPRING® mechanism
The P.E.I. equipped with the SURE-SPRING® mechanism, they represent the most advanced stage of technical innovation in the field of shutter rollers.
- Suitable for HIGH-SPEED work
- The multiple springs remain COAXIAL with each other
- The springs NEVER INTERSECT each other
- REDUCTION of the overall diameters
- EXCELLENT reliability
- SPEED up to 150 m / min
- ACCELERATION up to 2g
- 2,000,000 movement guarantee
- SAFETY on anchoring the band to the tube because adhesive products are NOT used
- PRACTICALITY in maintenance as the replacement of the band is very quick and simple
- Also suitable for work environments with STRONG AGGRESSIVE chemicals
- HEALTHY for the environment
SURE-SPRING® HP VERSION
SURE-SPRING® Mechanism HP VERSION
The SURE-SPRING HP winding mechanism responds to the need for an increase in power required by the winding of very large protection.
The optimal sizing of the springs develops an adequate towing power for the movement of the “J” Series Shutters
Translation of motion
The rotational movement of the tube with respect to the fixed central pin is obtained by means of a sliding toothed member.
This system allows you to compensate for the elongation of multiple springs by means of an axial displacement of the fixing of the springs themselves using a multi-start threaded pin.
Innovative characteristics
This new system allows multiple springs to work with an optimal shape, keeping the coils closed thanks to their sliding movement along the axis.
Fixing terminals
Mechanical fixing of the band on the tube
It is the most reliable method to ensure the safety of anchoring the band to the tube.
Scheme
SURE-SPRING® operation diagram
- In the roller n ° 1 (traditional system) the springs are fixed to the heads housed at the ends of the pin. In this execution, the springs are arranged, during winding or unwinding, in a typical helical configuration with obvious wear problems due to rubbing between the coils themselves, as well as between the coils and the central shaft.
- In the roller n° 2 (SURE-SPRING® system), the springs are fixed to a movable head which, during winding and unwinding, slides longitudinally, always keep the coils of the springs packed and concentric. This shape of the springs avoids most of the wear mentioned above, allowing much higher performance and a much longer operating life of the shutter roller.
