The Ridder RB120Eᵖˡᵘˢ tubular motor is a maintenance-free drive unit for driving roll-up screen systems (roof roller-screen NOT PERMITTED, refer to RPR PowerRoller) in greenhouses and livestock houses. The tube motor is integrated as standard into a 63 mm aluminium tube (wall thickness 1.5 mm) and can be used with 63 mm roll tubes. Because it is integrated, the tube motor can be wound up completely.
The almost-silent RB120Eᵖˡᵘˢ tube motor is fitted with a 1-phase 2-core asynchronous electric motor, an integrated brake and permanently lubricated planetary gear unit. The tube motor has a self-repairing thermal protection system, which prevents the burn-out of the drive if the electric motor should overheat.
The RB120Eᵖˡᵘˢ tube motor is almost entirely water resistant. The high protection class, IP55, means that the function of the tube motor will not be affected by a damp atmosphere.
