What is the Heated Air Curtain?
A heated air curtain is a fan-driven device that converts cold or natural air into heated air using various heat sources. Its primary function is to maintain uniform heating in your workplace and block out cold air from entering.
Types of Heated Air Curtain
Heated air curtains can be divided into two types according to different heat sources, and different types of heated air curtains determine different applications.
Electric Heated Air Curtain
Electric heated air curtains are the most commonly used type of heated air curtain. As you can see, they rely on electricity to generate heat.
They use an industrial three-phase power supply as their input power source and utilize a PTC ceramic heater paired with a high-density thermistor. After startup, current flows through the resistor, raising its temperature and heating the air passing through it.
Electric heated air curtains offer high heating efficiency and can output adjustable power in 3-12 kW to achieve multi-speed adjustment. Most importantly, they heat up quickly, delivering heated air in as little as 60 seconds, and they also provide a high air volume.
If you are running a hotel, restaurant, or shopping mall, then electric heated air curtains are very suitable for installation above the entrance or revolving door. Electric heated air curtains can provide a more comfortable environment for your guest area.
Water/Steam Heated Air Curtain
Water/steam-heated air curtains are also a very popular type of heated air curtain. Unlike electric heating, they utilize a wet heating system, using hot water or steam to heat the air and produce hot air.
This type of heated air curtain only requires power to operate the motor, not electricity for heating. This makes it more energy-efficient than electric heating.
However, water/steam-heated air curtains require a continuous flow of heat medium. This means your building will need to be able to provide hot water at 60-85°C or steam at 0.2 MPa-0.6 MPa to heat the air curtains.
Because of their unique heating method, the installation of water/steam-heated air curtains requires leak-free joints, which places high demands on the installation environment and workmanship. If you are located in a cold, high-latitude area with centralized heating, this type of heated air curtain may be a good choice
Benefits of the Heated Air Curtain
Save Energy and Cost
The biggest advantage of heated air curtains is their energy efficiency. They are typically used in conjunction with air conditioning or heating systems. They prevent heated air from escaping, reducing air conditioning energy waste and making the HVAC system more efficient.
In addition, heated air curtains can reduce the workload of the HVAC system, thereby reducing equipment maintenance and even replacement costs.
Improve Environmental Comfort
Another important function is the barrier function. It can prevent dust, dirt, flying insects, and bad smellsfrom entering the interior. The heated air curtain can help you get rid of 80% flying insects to improve the sanitary conditions. The filters in air curtains can improve the air quality by reducing 70% air pollution, thus keeping the air fresh.
In restaurants, canteens, and other dining venues, heated air curtains can prevent fumes and odors from the kitchen from entering the dining area. In industrial settings, trucks entering and exiting inevitably bring exhaust fumes into the workshop. Heated air curtains can keep the air in your workshop fresh and protect worker health.
All in all, the air curtain can improve the environmental comfort for your staff or guests.
Improved Visibility and Safety
The heated air curtain provides an invisible barrier that improves visibility. Especially at the doors of some workplaces and transfer stations, air curtains can reduce the occurrence of accidents such as collisions.
In addition, in cold weather, the heated air curtain can reduce the impact of outdoor fog. If your area receives a lot of snow, heated air curtains can also prevent ice and moisture from accumulating on the floor outside your doorway. Heated air curtains can keep the floor dry and prevent it from freezing.
It enables quick evacuation in the event of fire or other emergencies without the obstruction of physical barriers. The air flow formed by the air curtain can also slow down the spread of smoke to a certain extent.
Applications of Heated Air Curtain
Commercial Buildings
Heated air curtains are widely used in commercial buildings. They improve indoor air quality while reducing energy consumption in air conditioning systems, creating a comfortable working and shopping environment.
Typical applications include installing heated air curtains in shopping malls’ gates to prevent cold air from getting in. In addition, in places like restaurants and entertainment venues where doors are constantly opening and closing, heated air curtains can reduce indoor heat loss by 60%-80% to keep the indoor temperature stable.
Industrial Buildings
During production and processing in industrial buildings, harmful gases and dust are inevitably generated. Heated air curtains can improve indoor comfort in industrial buildings by removing harmful gases and dust, protecting worker health while improving productivity, thus ensuring production efficiency.
How to Install a Heated Air Curtain?
Independent testing has shown that properly installed heated air curtains can reduce indoor energy loss when the door is open by up to 80%. Installing heated air curtains is easy and involves the following steps.
Step 1: Position
First, remove the base plate behind the heated air curtain and position it where you want to install it. Then, secure the base plate to the wall.
Typically, if you’re installing it on a concrete wall, you’ll use expansion screws. For wood or metal walls, you can use various self-tapping screws. It’s crucial to ensure there are no gaps between the wall and the base plate, ensuring a tight fit.
Step 2: Install the Heated Air Curtain
Place the included hanging plate on the heating air curtain. Keep the air outlet facing downwards, hang the heating air curtain on the base plate, and firmly fix the base plate and hanging plate with screws.
Step 3: Turn On the Power
Open the junction box and wire it according to your voltage. For 220V, connect the ground, neutral, and one live wire, while for 380V, connect the ground, neutral, and three live wires. Then reassemble the junction box.
Turn on the power to test the air output of the heated air curtain. If the heated air curtain operates normally and does not wobble, the installation is successful.
The installation methods for air curtains of different models and sizes are slightly different. If you have any questions during installation, please contact Aosun, and we will provide you with professional installation advice.
