Choosing an electric air curtain wisely: useful tips and recommendations that you need to know before buying

Keeping the cold out takes precedence when winter arrives. One of the best ways to save energy and keep a comfortable temperature inside is with an electric air curtain. But it can be a little overwhelming to choose the best option when there are so many available.

Energy efficiency, noise levels, and installation requirements are important considerations whether you’re installing one in your house or a commercial space. By doing your research, you can make sure that your electric air curtain fits in perfectly with your decor and operates as intended.

This post will walk you through the most important suggestions and advice for selecting an electric air curtain that suits your needs and ensures that you are making a prudent purchase. Let’s examine the information you should have before completing that purchase.

Operating principle, purpose

An air curtain is essentially a directional fan heater that is mounted on a gate, entrance door, etc.

Such a device’s traditional design consists of:

• an elongated steel body with an air intake grille;
• a turbine of a special design;
• a heating element;
• an air outlet nozzle.

The temperature of the air in the doorway can be monitored and adjusted with the help of sensors and a thermostat found in almost every model of contemporary air curtains.

Air-heat curtains have a very basic working principle. A strong internal fan directs high-speed airflow in one direction, creating a "invisible barrier" that separates the room from the street. An obstruction like this prevents air from leaving the room and from penetrating the interior street air.

Any time of year can be enjoyed with a well-chosen heat curtain model: in the winter, the heat core keeps the cold air from the street from entering the heated space; in the summer, the directed air flow lets you keep the room cool while shielding the area from dust and insects from the street.

Thermal curtains have many applications: they are put in place at door and window openings in establishments with good cross-country mobility, such as stores, eateries, airports, stations, offices, and storage facilities, as well as in theaters, polyclinics, and professional settings. The cost-effectiveness of these devices has also been recognized by private homeowners, who have installed thermal curtains over garage and home workshop doors in recent years. Zone the space with ease with the aid of air-heat curtains. For instance, you don’t even need to install extra doors to "fence off" a private home’s hallway from the interior living areas.

Types of air curtains

How can I select the ideal air curtain? Depending on the coolant type and installation technique, all current models can be categorized.

By installation type

There are three kinds of air curtains available today:

1. Horizontal. Classic design. Installed directly above door (window) openings. As a rule, these are small economy class models, with a capacity of up to 5-6 kW;
2. Vertical. Installed only vertically at the side of the opening. This installation method is chosen in the case when, for one reason or another, horizontal installation is impossible or inconvenient. Today, the climate control equipment market offers designer models of vertical installation, released in the form of columns;
3. Built-in. They are characterized by the fact that the device body is completely hidden under the suspended ceiling. Directed air flow comes out of a nozzle hidden behind a decorative grille.

Universal air curtains, which can be positioned both vertically to the side of the opening and horizontally above it, have recently become available on the Russian market for climate control equipment.

By type of coolant

There are three categories for all air curtains based on how the air is heated:

1. Gas;
2. Water;
3. Electric.

Gas curtain Electrical drape A curtain of water

Propane is burned in gas air-heat curtains to heat the air. These are very specific pieces of equipment that are installed in large businesses that see high volumes of traffic during peak hours. Such systems are not utilized in buildings smaller than sixty square meters. distinguished by high cost, operating cost, and efficiency.

When the heating system or DHW have good access, water air-heat curtains are selected. The equipment works on this principle: hot water from the system goes through a heat exchanger that is powered by a turbine. Owing to issues with coolant availability and supply, there are no low-cost models of water curtains that are longer than one meter.

The primary benefits of these models are:

• minimum power consumption;
• low noise level during operation;
• affordable price;
• long service life;
• high technical characteristics.

Among our countrymen, electric thermal curtains have great popularity. The apparatus is suitable for use in nearly every setting, ranging from industrial gates to tiny windows and doors (with capacities as high as 2.5 kW). Principal benefits:

• availability of the coolant;
• easy control.

The substantial power consumption during operation is regarded as a drawback.

Criteria for choosing thermal curtains

What is the best way to select a thermal curtain? When selecting a model, there are a number of factors to consider, including the device’s necessary length, air flow, turbine design, the kind and power of the heating elements, installation style, curtain control method, etc. We’ll examine these parameters in greater depth.

Dimensions

The length of the device is the first consideration when selecting an air-the-heat curtain. Select a model so that its length spans the doorway entirely, leaving no spaces or ragged edges. The consumer can choose from thermal curtains with sizes ranging from 600 to 2000 mm on the current climate equipment market. Typically, models are bought for 800-1000 mm standard doorways.

The room can be penetrated by outside air if these indicators are lower. The owner will deal with draft issues and a decrease in the curtain’s efficiency if the performance is too high.

The best performance of the curtain for a doorway with a width of 80–100 cm and a height of 2-2.2 m is approximately 900 m 3 /h, with a power of 6–8 kW (depending on the room area and device performance). These calculations were made. Our recommendation is to hire experts for more precise computations. Select a model whose power is 15% less than the ideal or estimated if the curtain is going to be installed inside the vestibule.

These days, a micathermic heater that allows you to adjust energy consumption modes is included in some high-end models.

Control

By control method, all models available in the Russian market can be categorized. The curtains are:

• electronic;
• mechanical;
• with or without a remote control.

Three mechanical buttons are present on the most basic devices:

1. Power on/off;
2. Fan start;
3. Turning on the heating element.

More intricately designed models have an electronic control system that enables:

1. Smooth or stepwise adjustment of the heating temperature;
2. Adjust the turbine rotation speed, changing the device performance;
3. Change the angle of the air flow;
4. Set the operating time of the device;
5. Control the built-in thermostat.

It is crucial to take the control’s implementation into account when selecting the best model. To guarantee the air curtain operates in the most comfortable manner, this is required. Selecting a model with both an electronic control panel and a remote control would be the best option.

Mounting method

These devices can be mounted vertically or horizontally, depending on the air curtain’s design and the size of the space. Only an expert can determine which air curtain is superior in a given situation.

Installing horizontally installation vertically Integrated drapery

Regarding the intricacy of installation and operation afterward, installing the device above the door is more cost-effective, accurate, and practical. There are instances where the room’s design elements make horizontal installation impossible. In this instance, the model you install on the opening’s side should be your choice.

Built-in models work well in spaces with suspended ceilings or niches that can accommodate this device structurally.

It’s crucial to realize that installing the device requires roughly 50 centimeters of clear space above or to the side of the opening when selecting your own model. In order to connect the device, you must set up a connection point, supply a power line with the necessary power, and install the required safety and protective devices.

Range of action

As previously mentioned, the primary function of the air curtain is to produce a dense air flow throughout the whole opening, which enables you to balance out outside influences on the room’s air quality.

The market for climate control equipment currently offers a variety of models with a range of 1.5 to 8 meters (the height of the "air canvas" without sacrificing quality characteristics).

Noise level

In order to minimize discomfort in the space, you should focus on silent models. It should be recognized that SNiP and SanPiN’s norms and requirements must be followed when installing the device in a residential area. Residential buildings have a 40 dB noise level during the day. When deciding which type of thermal curtain to install above a store or office door, look for models whose maximum noise level won’t go above 55 dB. The device’s technical documentation reflects this indicator.

Frequency of door opening

The device power selection is influenced by this parameter. The formula is straightforward: the equipment should be more powerful the more frequently the doors are opened. You can use an online calculator or get in touch with a specialized organization to make the accurate calculation.

Overheating shutdown

Contemporary models come with a respectable array of features that make using them easier. Based on their requirements and financial situation, each person evaluates the issue of functionality. The primary feature of the chosen model is its skillfully executed safety mechanism, which shuts down when it overheats. The inclusion of this feature will raise the model’s price slightly, but it will shield the device from untimely failure and spare you the money needed to fix it.

After compiling the information above, we created a summary table that includes suggestions for selecting an air curtain model for typical openings.
