Delta Roll 4000 Electrically Operated Door

Roller Shutters - Our Delta Roll 4000 electrically operated door is designed for areas where security and frequent use are of paramount importance. The door is electrically driven either via a safe drive motor gearbox or an inboard mounted motor with chain drive to the barrel plate wheel. All inboard drive doors are also fitted with a helical torsion spring inside the barrel and safety brake anti fall bearing on the non-motor end. Either of the drive systems is in full compliance with the latest European legislation relating to industrial doors. The size of the motor and spring is determined by the weight of the curtain.
