Air Curtains – Energy-Efficient Airflow Solutions

Air curtains, also known as Door Air Curtains, Door Heater or Airwalls, are essential tools for controlling indoor environments in commercial, industrial, and retail spaces. By creating a controlled airflow barrier at doorways, air curtains separate indoor and outdoor air, reducing energy loss, maintaining comfort, and enhancing hygiene. They are a versatile solution that meets the demands of businesses around the world.

Understanding Air Curtain Technology

Air curtains are advanced devices installed above doorways that create a continuous stream of air across an opening. This airflow acts as a barrier, separating indoor and outdoor environments, reducing energy loss, and improving comfort. Unlike a simple door, air curtains provide an invisible seal, maintaining the desired indoor climate while allowing easy access for people and goods.

They are suitable for a wide range of spaces, including retail stores, restaurants, industrial facilities, and public buildings, making them a versatile solution for businesses worldwide.

Up to 80% of the energy that escapes through an open door can be saved with a good door air curtain.

Benefits of using Air Curtains

Energy savings

Reduce heating and cooling costs by limiting air exchange.

Sustainability

Do your bit against waste! Airflow barriers support you in achieving your sustainability goals.

Enhanced comfort

Maintain stable temperatures indoors for staff and customers.

Climate control

Ideal for heated or refrigerated environments, maintaining desired conditions.

Seamless Access

Allows doors to remain open for people, deliveries, or carts while maintaining climate separation.

Improved hygiene

Prevent dust, insects, and airborne pollutants from entering interior spaces.

Types of Air Curtains

Choosing the right type of air curtain depends on the building type, doorway size, and specific operational requirements. Common categories include:

Teddington C-Series door air curtain in a shoe shop

Commercial solutions

Designed for shops, restaurants, offices, and other public spaces. Typically compact, quiet, and energy-efficient.

Teddington Ratioavent air curtain system for industrial halls

Industrial solutions

Built for warehouses, factories, and production facilities. They provide higher airflow, wider coverage, and can withstand demanding conditions.

Heated vs. Ambient Air Curtains

Heated Air Curtains

Heated systems combine effective airflow separation with additional heating to improve comfort in cooler environments. Depending on the building infrastructure and energy concept, different heating options are available:

  • PWW / Hot Water Heating: Connection to an existing central heating system, ideal for buildings with hot water supply, also in combination with heat pumps.

  • Electric Heating: A flexible solution where no hot water system is available, offering quick and responsive heat output.

  • VRF Systems (R410A / R32): Integrated with modern HVAC and VRF systems, enabling efficient heating using refrigerant-based technology.

  • Hybrid Solutions: Combines the advantages of hot water and electric heating.

  • Steam/hot water: Powerful for industrial applications.

These options allow warm air curtains to be tailored precisely to the building’s heating strategy and comfort requirements.


Ambient Air Curtains

Ambient units focus solely on creating a powerful airflow barrier to separate indoor and outdoor air without adding heat. They are highly energy-efficient and particularly suitable where temperature control is handled by other systems or where heating is not required.

All types can be adapted to different door heights, widths, and usage frequencies, ensuring optimal performance, efficiency, and comfort across a wide range of applications.

Choosing the right Air Curtain

Selecting an air curtain involves evaluating several factors, e.g.:

Door dimensions

Height and width determine the required airflow strength.

Structural Conditions

Consider the available space above the door, whether the device will be integrated into a suspended ceiling, or if a freestanding unit is required. Proper installation ensures optimal airflow and functionality.

Heating

Even a ambient system provides effective shielding and saves energy. However, people find it more pleasant when the air is heated. In addition, the area around the door is heated more effectively.

Control options

Manual switches, motion sensors, or integration with building management systems allow for efficient operation.

Required Performance

In areas with high wind exposure at entrances or where buildings experience positive or negative pressure, a more powerful system may be necessary to maintain an effective barrier.

Usage frequency

High-traffic doors need more robust units.
