RSO Roller-shutter Operators


• Robust construction
Two words: Oblique gear. This proven transmission type, coupled with an AC motor that packs plenty of clout, makes for an industrial roller-shutter operator that makes quick work of even the heaviest of shutters.

• Fail-safe manual operation
What is strength without reliability? In the unlikely event that something goes wrong, the RSO is committed to keeping you in business, with not one but two modes of manual operation. All RSO models come standard with a five metre hand chain, ensuring that the shutter can be easily operated even from ground level, as well as a manual-release pin inside the gearbox that can override the mechanical brake.

• Easy to commission
The strength of a good industrial operator lies not in its complexity, but in its…well…strength. The RSO range of operators is exceptionally easy to set up, and commissioning can be done in mere minutes thanks to a user-friendly cam system.

• Reliable position control
Two mechanical limit switches are the heroes that tame the beast, making sure that the shutter stops in the open and closed positions, every time.

• Rock-solid mounting system
One can imagine that it takes quite a lot of muscle to keep such a colossus suspended several meters in the air – fortunately, CENTURION’s custom-made RSO mounting plates are more than up to the challenge, and includes vertical slots for easy adjustment of the operator.”
