Revolving Door Retrofit Kits in Dubai: Upgrade Old Revolving Doors Without Full Replacement (2026)

Many of Dubai's older office towers and hotels still run their original automatic revolving doors from the building's first fit-out — often 10, 15, or even 20 years old. The motor still turns, but the belt slips, the safety sensors are outdated, and spare parts are getting harder to source. The good news: in most cases, the answer isn't to rip out the whole revolving door and rebuild the entrance. It's a revolving door retrofit kit.

What Is a Revolving Door Retrofit Kit?

A retrofit kit replaces the worn mechanical and safety components of an existing revolving door — drive system, sensors, control electronics, and wear parts — while keeping the door's structural wings, canopy, and enclosure in place. It's the same principle as retrofitting an old car engine rather than buying a new car: the shell stays, the parts that fail get replaced with current-generation equivalents.

What's Typically Included in a Merac Retrofit Kit

• Drive belt replacement — high-strength rubber timer belts (e.g. DORMA XL-series compatible) to replace stretched or cracked original belts
• Safety sensors — vertical laser (Time-of-Flight) sensors and radar motion detectors to bring the door up to current presence-detection standards
• Emergency stop button — a dedicated, clearly marked stop control for building safety compliance
• Safety bumper — pressure-sensitive rubber bumpers on the leading edge of each wing
• Slip ring replacement — restores clean power/signal transfer through the rotating canopy for smooth, uninterrupted operation
• Brush seals — fresh horsehair brush seals to cut draft, dust, and noise between wings and the enclosure
• Program switch / control panel — updated control logic for speed settings, night locking, and emergency collapse (breakout) mode

When Retrofitting Makes Sense vs Full Replacement

Retrofitting is the right call when the revolving door's structural frame, glass wings, and canopy are still sound but the drive, sensors, or controls are failing or obsolete. It typically costs a fraction of a full replacement and can often be completed with minimal disruption to the entrance — important for towers, banks, and hotels where the main entrance can't be closed for weeks. Full replacement only becomes necessary when the structural frame is damaged, the footprint needs to change, or the original manufacturer no longer supports the model at all.

Completed Revolving Door Retrofit Projects by Merac Dubai

Silmen Merac has successfully completed revolving door retrofit projects at several landmark properties across Dubai, including:

• Hilliana Tower, Al Sofouh, Dubai
• Hanover Tower, Jumeirah Village Circle (JVC), Dubai
• CBI Bank, Jumeirah Beach Road, Dubai
• Crowne Plaza, Sheikh Zayed Road, Dubai

Each of these retrofits replaced worn drive, sensor, and safety components on the buildings' existing revolving doors — restoring smooth, safe operation without the cost and disruption of a full entrance rebuild.

Benefits of a Revolving Door Retrofit

• Lower cost than full replacement — you keep the existing structure and glazing
• Faster turnaround — no structural works, no long entrance closures
• Improved safety compliance — modern sensors and emergency stop controls bring older doors up to current standards
• Better energy efficiency — a revolving door that seals and rotates properly keeps conditioned air inside far better than a worn, gappy one
• Extended service life — gives an aging revolving door another decade of reliable operation

How the Retrofit Process Works

1. Site survey — Merac's technicians inspect the door, identify the manufacturer/model, and diagnose which components need replacing
2. Parts sourcing — compatible belts, sensors, and control components are sourced or fabricated to match the existing door
3. Installation — retrofit works are scheduled around the building's operating hours to minimise disruption to the entrance
4. Testing and handover — the door is tested through full rotation cycles, safety sensors and emergency stop are verified, and the system is handed back to facility management

Retrofit work can also be bundled into an ongoing Annual Maintenance Contract (AMC), so the newly retrofitted components are inspected and serviced on a regular schedule going forward.

Need a Revolving Door Retrofit in Dubai?

If your building's revolving door is slowing down, jamming, or running on outdated safety sensors, Merac Dubai can retrofit it rather than replace it — the same approach we've used successfully at Hilliana Tower, Hanover Tower, CBI Bank, and Crowne Plaza.
