Comprehensive Maintenance & Restoration of Dorma Automatic Door Entrance Systems

The Challenge:

As one of the most frequented luxury hotels in the region, Pamodzi Hotel experiences exceptionally high foot traffic daily, with guests, delegates, and visitors continuously passing through its main entrance points. Over time, the automatic door systems had begun showing signs of wear, including inconsistent sensor responses, delayed opening mechanisms, unusual operational noises, and intermittent controller faults. These issues not only affected the guest experience but also posed potential safety concerns that required immediate professional attention.

Our Approach:

Our Trained technicians conducted a thorough diagnostic assessment of each Dorma automatic door unit, examining every component from the drive motors and belt systems to the sophisticated electronic controllers and safety sensors. The Dorma controllers, renowned for their German engineering excellence, required specialized expertise to properly calibrate and maintain—expertise that Keystone Pro has developed through years of dedicated training and hands-on experience with premium door automation systems.

Scope of Work:

Our comprehensive maintenance service included:

• Complete inspection and testing of all Dorma ES200 and ED200 controller units
  Cleaning and lubrication of guide rails, rollers, and drive mechanisms

   

• Calibration of motion sensors and safety photocells to ensure optimal detection ranges

   

• Adjustment of door opening/closing speeds and hold-open times

   

• Replacement of worn drive belts and hanging components

   

• Electrical connection inspection and terminal tightening
   
• Safety compliance testing in accordance with international standards
  Results Delivered:

Upon completion of our maintenance program, all automatic door entrance systems at Pamodzi Hotel were restored to peak operational condition. The doors now operate with whisper-quiet precision, opening smoothly as guests approach and closing securely behind them. Sensor responsiveness has been optimized to provide the perfect balance between accessibility and energy efficiency, reducing air conditioning losses through the entrance areas.

The hotel management expressed their satisfaction with the noticeable improvement in door performance, noting that guests have commented positively on the seamless, welcoming entrance experience. The preventive maintenance measures we implemented are projected to significantly extend the operational lifespan of these premium door systems, delivering excellent long-term value for the hotel's investment.
