How fast do automatic doors open?

Types of Automatic Doors

Automatic doors have become an integral part of modern architectural designs. These doors offer a blend of convenience, aesthetic appeal, and enhanced security. As technology evolves, various types of automatic doors have emerged, each serving specific purposes. Let’s delve into the different types of automatic doors available in the market.

Sliding Doors

Sliding doors are among the most common types of automatic doors seen in commercial spaces, especially in places with high foot traffic.

  • Mechanism: These doors operate by sliding horizontally, usually parallel to a wall. They utilize a set of tracks and rollers for smooth operation.
  • Popular Use Cases: Airports, shopping malls, and office entrances are prime examples.
  • Advantages: They are space-efficient and can handle large volumes of traffic.
  • Considerations: Regular maintenance is essential to ensure the rollers don’t get stuck.

Revolving Doors

Revolving doors consist of several wings or leaves that rotate around a central axis.

  • Mechanism: The rotation can be powered or can be manually pushed.
  • Popular Use Cases: Hotels, large commercial buildings, and skyscrapers often feature revolving doors.
  • Advantages: They are excellent for maintaining indoor temperatures, preventing drafts, and allowing continuous flow of traffic.
  • Considerations: Regular maintenance is needed, especially for the central pivot point.

Folding Doors

Folding doors, as the name suggests, fold into or out of an entrance, usually in a zigzag pattern.

  • Mechanism: Panels are connected via hinges, allowing them to fold as they open or close.
  • Popular Use Cases: Residential spaces, patios, and some commercial establishments.
  • Advantages: Ideal for spaces with wide openings but limited rolling or swinging space.
  • Considerations: Ensuring all panels fold uniformly and smoothly is essential.

Roller Doors

Roller doors, commonly used for garages, roll upwards to open and downwards to close.

  • Mechanism: The door is made of horizontal slats or panels which roll on a track.
  • Popular Use Cases: Garages, storage units, and commercial warehouses.
  • Advantages: Provides robust security and can be made with various materials including steel or aluminum.
  • Considerations: Regular check-ups for the rolling mechanism can prevent jamming or uneven rolling.

Factors Influencing the Speed of Automatic Doors

The speed at which automatic doors operate is not merely a random setting but is influenced by various technical and environmental factors. Fast or slow, the speed of these doors can impact energy costs, safety, and the user experience. Let’s explore the different factors that dictate the pace of automatic doors.


Door Weight and Material

The weight and the material from which a door is made can significantly influence its operational speed.

  • Heavy Doors: Doors made from dense materials like hardwood or metal might operate slower due to their weight, requiring more force to move them.
  • Lightweight Doors: Doors made of lighter materials, such as PVC or certain composites, tend to open or close faster due to reduced resistance.
  • Materials’ Properties: The wear and tear, rigidity, and durability of the material also play roles in affecting the speed over time.

Power Source and Voltage

The source and stability of power, along with the supplied voltage, directly affect the door’s speed.

  • Consistent Power: Doors receiving a consistent power supply can maintain a steady speed.
  • Voltage Fluctuations: Variations in voltage might lead to speed inconsistencies. For instance, a drop in voltage could slow the door’s operation.
  • Backup Power: In cases of power loss, backup sources may not provide the same power level, potentially affecting speed.

Sensors and Activation Methods

The type of sensors and their responsiveness play an essential role in determining how quickly a door reacts.

  • Sensor Types: Infrared sensors, motion detectors, or pressure mats have different response times and ranges.
  • Calibration: Properly calibrated sensors ensure the door starts its operation at the right time, making its speed more effective.
  • Activation Methods: Doors activated manually, say with a push button, may have a slight delay compared to those activated by sensors.

Benefits of Optimal Door Speed

Setting the correct speed for automatic doors is more than just ensuring they open and close efficiently. Optimal door speed provides an array of benefits ranging from energy conservation to safety and efficient traffic management. Here’s why getting the speed just right matters.

Advantages and types of Automatic Doors

Energy Efficiency and Temperature Control

Ensuring doors operate at an optimal speed can be a boon for energy savings and maintaining desired indoor temperatures.

  • Quick Closures: Fast-closing doors can prevent excessive heat or cold from entering a building, which helps in reducing HVAC loads.
  • Energy Consumption: Efficient door operations can lower the energy footprint by reducing the time motors are operational.
  • Weather Impact: During extreme weather conditions, the right door speed can minimize the effect of external temperatures on indoor comfort.

Safety Considerations

Safety is paramount, and the speed of automatic doors directly contributes to it.

  • Avoiding Accidents: A door that closes too quickly might pose a risk to individuals, especially children or the elderly.
  • Sensor Coordination: The door speed should align with sensor responsiveness to ensure users have enough time to safely pass.
  • Emergency Situations: Optimal speeds can ensure doors open or close rapidly in emergencies without causing panic or obstructions.
