12 Guides Air curtains Applications [2022 Reviews]

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.

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.

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.

Sanitation is the basic condition for the survival of the restaurant. Failure to pay attention to restaurant hygiene will not only affect the health of customers but also the restaurant owner will face more serious consequences. In the dining hall, having a good dining environment will attract more customers, and business will flourish.

The air curtain can create an invisible door to block the outside dust layer, harmful gases, flying insects, save energy, and so on. Of course, in different places, the model and purpose of using the air curtain are also different. Let me give you some analysis.

Restaurant Entrance Door:

Restaurant entrance door, often need open often or long time to open, because the door has to be opened to welcome customers. If not without air curtains, harmful insects such as dust, polluted gas, and flies will take advantage of the void and entre restaurant.

Often at the entrance door, a stronger (higher air speed) air curtain is selected. Generally small restaurants, the door height will not be over three meters, so you can choose the cross-flow type air curtains. For some high-end star hotels, they have higher doors and higher ceilings, so centrifugal type air curtains are needed to install them to ensure effects.

Kitchen Entrance Door:

The air curtain can isolate the exchange of odors between the kitchen and the dining area to prevent the cooking fumes from being emitted to the dining area.

Then, the air curtain can also isolate external flies and harmful gases from entering the kitchen. If chefs process and prepare catering food in a place with serious environmental pollution, it will have a great impact on food safety, and customers will eat unclean food. It will have an impact on health.

And if the kitchen is not clean and flies are flying in the sky, the chef’s mood will be affected and the food will be unpalatable. It is a huge loss of restaurant customers. Food hygiene, cleanliness, safety, and reliability are the first priority.

Restaurant cold storage door

Some large restaurants, often have independent cold storage, which requires the air curtain to be installed at the entrance outside the cold storage, which can save electricity bills and isolate external polluted air or pests.

Restaurant back door/unloading door

For the back door or the unloading door, it is often necessary to open it in stages. The environment of the back door is often worse, that is, more flies. Therefore, a stronger air curtain is required, preferably with a magnetic switch, it will operate when the door opens, and stop when the door closed.

For restaurants, the air curtain is to maintain a more comfortable and high-quality environment, thereby improving food safety while saving energy costs, improving customer satisfaction, improving employee comfort.
