Automation for Roller Shutters

Tubular Motors and Central Drives for Roller Shutters

DoorHan roller shutter automation systems provide compact, powerful, and whisper-quiet motorization for residential window shutters, commercial shopfronts, and industrial roll-up doors. Engineered to slide directly inside the rolling shutter steel octagonal shaft (40 mm, 60 mm, 70 mm, 102 mm), DoorHan tubular motors provide invisible, space-saving drive power without requiring external motor brackets.

Available in a wide range of torque ratings (from 10 Nm up to 300 Nm), our tubular motors include models with integrated manual emergency crank override (NHK series) and built-in radio receivers.

Key Technical Specifications & Engineering Standards:

• Compact Tubular Design: Fits neatly inside the winding barrel, preserving clean architectural aesthetics and saving overhead space.
• Mechanical Manual Crank Override: Integrated emergency crank mechanism enables manual operation of storefront shutters during electrical power cuts.
• Electromagnetic Disc Brake: Instant mechanical braking holds the shutter firmly locked in any intermediate position.
• High Thermal Duty: Built-in thermal cut-off sensor prevents motor overheating during repeated consecutive cycles.
• Centralized & Group Control: Compatible with multi-channel group controllers for simultaneous or sequential automation of entire building facades.

Quality Assurance & Engineering Compliance:

DoorHan commercial and industrial roller shutters and steel rolling doors are manufactured in full compliance with European safety standard EN 13241-1 and ISO 9001:2015. Slats and bottom profiles undergo continuous roll-forming inspections, high-tensile wind lock retention tests, and anti-corrosion salt spray verification. We supply civil contractors with detailed guide rail anchoring details, hood dimensions, and electrical motor interface manuals.

DoorHan roller shutter motors provide effortless everyday automated shading, insulation control, and commercial physical security.
