Comparison of Automatic Sliding Door and Automatic Revolving Door

Automatic Sliding Door and Automatic Revolving Door are the 2 key products and hot sale doors from TSTC Automatic Doors. Do you know the big differences from these 2 type of doors ? Here is the answer as below . 

▪ Automatic Sliding Doors

Definition: Doors that open horizontally via motor-driven tracks, commonly used in commercial and healthcare settings.

Advantages:

Space Efficiency: Ideal for limited spaces, telescopic (foldable) designs maximize opening width while minimizing footprint.

Smooth surfaces (stainless steel/glass) resist corrosion and enable easy disinfection.

Safety & Accessibility: Force-sensitive reversal stops or reverses upon collision, reducing injury risks. Non-contact operation via sensors/buttons supports infection control.

Energy Savings: Rapid closing minimizes air exchange, cutting HVAC costs.

Low Noise: PWM-driven motors and silent tracks (<49 dB) suit quiet environments.

Disadvantages:

Limited Flow Capacity: Smaller openings may cause bottlenecks during peak traffic.

Reduced Wind Resistance: Less effective in high-wind areas compared to revolving doors.

Dependency on Tracks: Debris accumulation in tracks can disrupt operation, requiring frequent maintenance.

Key Applications:

Healthcare: Operating rooms, isolation wards, Hospitals, pharmaceutical facilities.

Laboratories/Cleanrooms: Spaces demanding strict contamination control.

Offices/Retail: Entrances with space constraints or moderate foot traffic.

▪ Automatic Revolving Doors

Definition: Rotating doors with 2–4 wings, typically installed at high-traffic building entrances.

Advantages:

Energy Efficiency:"Always open, always closed" design reduces air infiltration by >30%, maintaining indoor temperatures.

Critical for climates with extreme heating/cooling demands.

Wind & Weather Resistance: Seals against drafts, rain, and dust, enhancing lobby comfort.

Aesthetic Prestige: Creates a luxurious entrance for hotels, corporate towers, and upscale retail.

Crowd Management: Controls flow rate (e.g., a 2m-diameter door handles ~2,400 people/hour).

Advanced Safety Features:Anti-pinch sensors, emergency brakes, and foldable wings for evacuation.

Disadvantages:

High Costs: 3–5× more expensive than sliding doors due to complex mechanics.

Accessibility Challenges: Difficult for wheelchairs, strollers, or large luggage; requires supplemental side doors.

Maintenance Demands: Frequent servicing needed for sensors, motors, and seals.

Emergency Limitations: Despite foldable wings, panic during evacuations may cause jams.

Noise Issues: Motor/rotation sounds can disrupt quiet settings (e.g., libraries).

Key Applications:

Hospitality: Luxury hotels, resorts, and convention centers.

Corporate/Public Buildings: Skyscrapers, banks, and airports.

Shopping Malls: High-end retail entrances.

▪ Summary Comparison

▪ Conclusion

Choose sliding doors for hygiene-critical or space-limited sites (e.g., labs, hospitals). Opt for revolving doors in energy-sensitive, high-prestige entrances with heavy traffic (e.g., hotels, offices). Pairing both types-e.g., revolving doors with sliding emergency exits-optimizes efficiency and safety .
