The original intention of the air curtain is for climate protection, which prevents the exchange of indoor and outdoor air after opening the door.

When the door is opened, if, without air curtains, the heated or cooled air in the room will flow out, causing energy loss. After the air curtains, it can up to 80% of the energy loss be saved. Under normal circumstances, the average payback period of the air curtains is 2 to 3 years.

We can also use it to prevent dust, outdoor pollution, prevent flying insects from entering, keep the indoor air clean, and improve the comfort of employees or customers.

  • Increased available space near the door area

Retail Stores and Convenience Stores

For retail stores and 24-hour convenience stores (such as 7-11, Go-Mart, Circle K, etc.), economical type air curtains are required to be installed. For this kind of small store or small business places, some stores have only one entrance, and some stores have two doors, which are divided into front entrances and back entrances.

Regardless of the front door and the back door, they need to be protected by an air curtain, but there are some differences in choosing the type of air curtain.

The front door is the place where customers enter and exit. These places are sometimes required to add a door sensor device (auto operation) and heating function, and some even require the air curtain to have a decorative. For the rear door, it is the unloading area and the surrounding environment is more complicated, so it needs an air curtain with stronger air speed to maintain it.

Why Need Air Curtains Used in Retail Stores and Convenience Stores?

Cold Storage and Refrigeration

Some food, Cargo, or medical supplies need put in cold storage. In the cold storage, the temperature can reach minus 30 degrees, which will form a huge temperature difference with the outdoors. The greater the temperature difference, the faster the temperature exchange between inside and outside when the door is opened, the greater the energy loss.

Moreover, if cooled air is lost, it will become a temperature abnormality in the cold storage, which will have a serious impact on food safety and cargo safety in the cold storage. It is strongly recommended to install an air curtain to reduce energy loss when the door is opened.

After opening the door, the temperature in the cold store rises to the set value, and the refrigeration device starts to work and cool. In the absence of an air curtain, the compressor has a higher working frequency and longer operation time. Therefore, the air curtain can reduce the burden of refrigeration equipment and extend their used life.

At the door of the cold storage, fog and icing are often generated. Not only will it damage the products in the cold storage, but it will also cause the ground to be smooth. Threat to worker safety and reducing transportation efficiency. Also need to remove those annoying ice layers and reduce the cost of deicing/frosting in the refrigerator.

Some places will adapt to PVC door curtains, but this isolation method will bring a lot of trouble. For example, after a period of use, the PVC door curtains are dirty, and the PVC door curtains are frequently pushed open, reducing work efficiency. The PVC door curtains will also obstruct the view. Illuminated as a potential collision hazard.

Therefore, the ROI of the air curtain is very high, and it can help cold storage companies save energy/money.
