Sliding telescopic systems
These utilize multiple overlapping leaves to maximize clear opening width in narrow corridors. They offer superior space efficiency compared to single-slide units in tight spaces.
Operational trade-offs
Advantages include maximizing traffic flow in restricted footprints. Limitations involve increased mechanical complexity and higher maintenance costs due to multi-track synchronized leaf drive systems.
Swing door operators
Electromechanical arms automate existing manual doors, making them ideal for retrofitting office entrances. While cost-effective, they require significant clearance space for leaf swing paths.
Operational trade-offs
Advantageous for low-cost accessibility upgrades. Limitations include limited traffic capacity and potential safety hazards if sensors are not correctly positioned for the swing arc.
Revolving door assemblies
High-performance circular systems maintain a constant seal between interior and exterior climates. They drastically reduce air infiltration but limit peak traffic flow speeds compared to sliding solutions.
Operational trade-offs
Superior for climate control and prestige entrances. The main limitation is the high upfront cost and inability to handle rapid, high-volume pedestrian surges effectively.
