What is the revolving doors
Revolving doors are widely used in commercial buildings, hotel, shopping centers, airports, hospitals and other high-traffic areas.There are four main advantage:
Energy Efficiency: Revolving doors help minimize the exchange of indoor and outdoor air, reducing the need for air conditioning and heating. This leads to significant energy savings for businesses.
Enhanced Security: Revolving doors are highly effective at preventing unauthorized access, improving overall building security. They are particularly beneficial in environments that require stringent security measures.
Improved People Flow: Revolving doors allow multiple people to pass through simultaneously, reducing queuing and wait times. This enhances overall efficiency, especially during peak periods.
Minimized External Disruptions: Revolving doors effectively block dust, wind, and noise from entering, helping to maintain a clean and quiet indoor environment.
Challenges for buildings with revolving doors
Temperature fluctuations due to frequent foot traffic
Frequent entry and exit of people can cause fluctuations in indoor temperatures. Although revolving doors are designed to minimize air exchange, the act of opening the door still allows outside air to enter, particularly during extreme weather conditions. This can result in an uncomfortable indoor environment, negatively impacting the experience of both customers and employees.
Energy Loss from Indoor-Outdoor Air Exchange
While revolving doors are designed to reduce the direct exchange of indoor and outdoor air, some air movement still occurs when the door is open. This air exchange can place additional strain on air conditioning and heating systems, leading to increased energy consumption. The impact on energy loss becomes especially significant during high-traffic periods, ultimately affecting the building’s overall energy efficiency and operating costs.
Intrusion of External Elements
Revolving doors, while effective at minimizing air exchange, cannot fully insulate the interior from the external environment when in operation. Even under normal use, external elements such as dust, insects, and noise can still find their way inside. This poses a significant challenge in industries where cleanliness and hygiene are paramount, such as food service or healthcare. The intrusion of airborne dust and insects can compromise the indoor environment, leading to increased cleaning and maintenance efforts.
What is an air curtain
An air curtain is a device installed above a doorway that creates an invisible air barrier by generating a strong airflow through a motor-driven impeller. This barrier prevents the direct exchange of indoor and outdoor air. The primary function of an air curtain is to block external elements—such as dust, insects, noise, and temperature fluctuations—from affecting indoor comfort.
When applied to revolving doors, air curtains can further enhance their effectiveness, providing an additional layer of protection and improving the overall performance of the door system.

Energy Efficiency
Air curtains create a strong air barrier that effectively blocks the direct exchange of indoor and outdoor air. This reduces the need for air conditioning and heating, minimizing energy loss. Studies have shown that buildings equipped with air curtains experience significantly lower energy bills in both summer and winter, resulting in cost savings for businesses.
Enhanced Comfort
Air curtains help maintain a stable indoor temperature, minimizing temperature fluctuations caused by external weather changes. This is especially beneficial in high-traffic areas, where air curtains can block cold and hot air, ensuring a more comfortable experience for customers and employees when entering and exiting. The improved comfort not only enhances the user experience but also boosts employee productivity.
Isolation of External Elements
Tirai udara, installed above revolving doors, effectively block the intrusion of external elements such as dust, insects, and noise. This is particularly important in industries like food service, healthcare, and retail, where cleanliness and hygiene are essential. By reducing the entry of contaminants from the outside, air curtains help maintain cleaner indoor environments, which in turn lowers the frequency and cost of cleaning and maintenance.
Enhanced Convenience
The installation of air curtains can improve the accessibility of revolving doors, especially in high-traffic commercial settings. Even when the revolving door is open, the air curtain continues to provide a protective barrier, ensuring smooth entry and exit for customers without the disruption of temperature fluctuations or external interference.
