In view of their design features some elements of the room leads to the fact that the heat leaves it without a fight, without a fight giving way to the street cold. It is no secret that being in such conditions is not only uncomfortable, but also fraught with health consequences. This problem can be solved with the help of the so-called thermal curtain. The principle of its operation is to create a barrier that prevents the leakage of heated air from the room and the penetration of cold air from the street into it.
The equipment that creates such a curtain varies depending on the heat source. The latter can be water or electricity. Experts say that a water thermal curtain is a more economical option. At the same time, her dignity is not diminished in any way, because she:
- Reduces heat loss in the room;
- Creates a barrier for both cold air and dust, insects, exhaust gases;
- Contributes to the blurring of the boundaries of temperature values inside and outside the room;
- Reduces almost to zero the possibility of drafts, which is important for health;
- Allows you to save money on heating in the cold season;
- Allows you to keep open front door without the associated inconveniences.
Creates a thermal curtain fan. Due to its high power, it generates a strong airflow. It is he who is an obstacle to the exit from the premises. warm air. For such a device to work, it is necessary to have central heating, since hot water serves as the source of heat for such a curtain.
The installation of such equipment is quite laborious, but this will soon be compensated by its effective work and low maintenance costs.
As a rule, installation is carried out above the doorway or to the side of it. In the first case, we are talking about a horizontal curtain, and in the second, a vertical one. If it is planned to install a vertical thermal curtain, then all calculations are recommended to be made on the basis that its height should be ¾ (or more) of the height of the doorway.
Fan - the main working element
The radial fan, which creates an air flow barrier, is rightfully considered the main constructive element device that creates a thermal curtain. The fan turbine, located along the entire length of the device, provides maximum efficiency and uniformity of the air flow.
The engine of the device is usually mounted on the side of the turbine, but there is another option: the centrally located engine is framed on the sides by small turbines. Such a solution is relevant in cases where the estimated length of a single-piece turbine exceeds 80 cm. It is rather difficult to manufacture it. A simplified version of the arrangement of turbines and an engine is, of course, cheaper, however, the protective properties of such a curtain will lose to the traditional version.

Control
To control the air curtain, at least two switches are usually used: one for the fan, the other for the heating elements. Additionally, the device can be equipped with two- or three-stage heating controllers. Upon reaching a certain temperature, the device can automatically turn off if a thermostat is installed in it.
The control panel for various models can be wired or built-in. The latter option often occurs when installing small curtains (above windows and doors). This is due to the inaccessibility of the control buttons. Remote controls are convenient because they can be installed in the desired location.
In premises such as a warehouse or hangar, it is advisable to use a limit switch. Its advantage lies in the fact that it brings the device into operation only when the door is open.
What to look for when choosing
The main criteria for choosing a water thermal curtain are:
- device power;
- its length;
- possibilities of management and regulation;
- performance indicators;
- type of instalation.
A number of criteria have already been considered, so it is necessary to dwell on the rest in more detail.
Air curtain performance
It determines the speed of the air flow generated by the fan and the possible mounting height. Example: if you install a curtain over a doorway 1 m wide and 2 m high, then it should "drive" about 700-900 m3 of air per hour. This performance will provide an air speed of 8 m / s near the device itself and 2 m / s near the floor. The degree of performance is directly proportional to the price of the product.
Power
It matters if the air curtain is supposed to be used as a heat source for space heating. It is not advisable to purchase a device with big power for places where there are no problems with heating.
If you purchased a device with a heating function, then please note that the air coming out of it will not be hot, only slightly warm. This is achieved by intensive blowing of the heating elements.
The length of the device can vary between 60-200 cm. The most popular length is 80-100 cm, as they are suitable for standard window and door openings. For industrial facilities other values are required. The length of the devices for them is calculated simply: it is equal to the width of the opening or slightly exceeds it.
Thus, the thermal curtain is an effective and modern facility keeping the heat in the room, regardless of its area.

Economic option climatic equipment are water thermal curtains. They protect the room from the cold, heat it and prevent the penetration of unwanted particles from the external environment. The heating element is the central heating system with hot water.
Air-water curtains are mounted in residential buildings and installed in non-residential premises. Equipment can be placed:
- Above the doorway
- Above the window
- On the sides of internal floors and passages.
Kinds
Water thermal curtain is divided into the following models:
- With horizontal (vertical) mounting. These curtains are used for gates. To cover the entire opening area, it is recommended to install vertical models. They create a directional lateral airflow,
- Ceiling. To hide risers, channels and the equipment itself, products that are built into suspended ceiling,
- special design. Created in the form of a segmented body. Similar Models suspended from the ceiling or placed vertically on the floor.

Design
The elements of the equipment are:
- A heating element,
- Nozzle,
- electric motor,
- Fan.
The functions of the heating element are performed by a two-way heat exchanger. It is created from copper pipes, which are equipped with lamellar aluminum fins. Through the nozzles that exit the housing, water is supplied to the heat exchanger.
Its connection to the heating network is implemented using flexible corrugated pipes. In winter, hot water may be turned off. Therefore, the devices are provided with a drain of water. The water thermal curtain, if properly installed, is free from corrosion. Its body is made of special materials. The insulation of internal elements is also made of special materials.
Operating principle
The equipment uses an air stream that is heated by the thermal energy coming from the heat exchanger. Electricity is consumed only for the rotation of the fan and comes from a 220 V network.
The blowing of thermal curtains and heating (partial, maximum) depend on the functioning of the fan. The water curtain is controlled by a remote control.

Thermal curtains are designed for a clear separation of air zones in which it is necessary different temperature, using a narrowly directed air stream. Such installations are used in various premises to create and maintain conditions of climatic comfort.
Depending on the source of energy used to heat the coolant, there are separating devices of the following types:
- water;
- electrical.
Water thermal curtains are climatic devices that create a narrow high-speed air stream to separate two different temperature areas. Installation thermal device above the door or window block provides the creation of a powerful air barrier that maintains the required temperature in the room when windows or doors are opened.
Heated water from central or autonomous water supply served in water thermal curtains as a source of thermal energy. Set optimum temperature heated water is set by a special regulator. The climatic household appliance has additional function, which provides effective ventilation without heating by using a built-in single-phase electric motor with a speed control.
Shop "Termomir" offers customers a wide range of thermal air curtains. Sale of heat curtains is carried out on the official website wholesale and retail.
One of the most effective options for protecting against the penetration of cold air into the room is a thermal curtain. With a wide air flow, the device separates the heated room from the cold air from the street, protects from dust and insects, provides a comfortable microclimate in the entrance area, saves energy for heating, and keeps air-conditioned rooms cool in summer.
Air curtains are installed on entrance groups buildings with a large number of visitors: in shopping and entertainment centers, metro lobbies, cafes and restaurants, large offices, banks, clinics, etc.
Curtains come with heating - electric and water (on hot water), as well as without heating - air.
Electric air curtains are powered by the mains, they can be both domestic and industrial, they usually have several operating modes with power switching and can work without heating ( summer mode). Curtains with a power of up to 5 kW operate at a mains voltage of 220 V, and from 5 kW and above - 380 V. Household curtains are actively used for doors in country houses and cottages.
Thermal water curtains differ from electric curtains in much greater power, therefore they are actively used for large objects - doorways and gates of large warehouses, shops, workshops, hangars, etc. Such air curtains are fixed-mounted, connected to the main hot water and are characterized by high efficiency and air capacity.
Air curtains without heating are used where it is necessary to separate the zone of heat and cold without additional heating. These devices are not equipped with heating elements, but work like large fans, allowing you to separate from heated rooms cold rooms, areas or warehouses with refrigerated products, prevent smoke and dust from entering other rooms, for example, in working shops and workshops, etc.
Thermal air curtains have the main technical characteristics: power, air capacity and installation height. According to these parameters, the calculation and selection of heat curtains is carried out. Dimensions are also important, or rather the width of the curtain - it should be sufficient to block the entire doorway, providing full protection.
Thermal curtains are most often produced in a horizontal version and are placed above the door or gate on the wall or ceiling. Veils vertical installation are placed on the side of the doorway and have an important characteristic no longer width, but height. Sometimes, at high doorways, several such curtains are used, installed one above the other. There are also models universal installation, which are connected from the side or from above at the request of the user. Thermal curtains often come with a remote control. remote control- keyboard, wired or wireless. Such a device greatly facilitates the use of the air curtain and increases comfort. A large assortment of thermal curtains is presented below on the page and in the menu of the site. If you find it difficult to make a choice, please contact our specialists for advice.

One of the main types of climate control equipment that reduces building heat loss is a water thermal curtain capable of operating in the presence of a central heating network or hot water supply.
Installations of this type are successfully used in the absence of the possibility of installing electrical units in residential and amenity premises, production shops, office and shopping centers.
The principle of operation of a water thermal curtain
Modern air curtains, water curtains are an improved air heater that provides the creation of a cut-off flow in door and window openings different section. The air flow is created with ventilation unit, which may have different design. The cut-off curtain is heated when air passes through a water heater, which is connected to the hot water supply network.
This design has whole line advantages over traditional electric heaters:
The use of thermal curtains in various modes allows not only to prevent the penetration of cold air into the room in winter. When the coolant is turned off, it works effectively even in the summer heat, in addition, such devices prevent insects and small animals from entering the serviced premises.
Classification of water thermal curtains
Specialists classify thermal water curtains according to a number of specifications. Moreover, each modification is most effective only for protecting premises under certain conditions.
According to thermal power, they distinguish:
- Household (local) thermal curtains, which can be used for installation on small openings. Most often, such installations can be found on the windows of stalls, small retail outlets, cash desks. They are also used as window curtains in residential premises.
- A thermal curtain of medium power is effective at an opening height of up to 3 meters. This category includes most of the modifications used to protect the entrances to shopping and office complexes.
- To protect the opening at a height of up to 7 meters, powerful thermal curtains are used. Most often they can be found in production and storage facilities, logistics centers.
- For large openings, heavy-duty curtains are used. Basically, such devices are produced according to individual orders on the basis of specially developed projects for the energy supply of buildings.
According to the method of installation, horizontal and vertical thermal water curtains are distinguished. Most often, horizontal modifications are used, which are mounted above the doorway. The use of several such units allows you to protect even very wide openings. When installing vertical curtains, they are mounted from one or two sides of the entrance, while in height they must cover at least 2/3 of the opening.
In some cases, built-in curtains are used, placed behind suspended structures ceiling. At the same time, only the air-supplying decorative grilles remain visible.
The most popular brands of thermal water curtains
The market is widely represented by products of both domestic and western manufacturers. The following brands are most in demand:

Basic rules for installing water curtains
For installation of air curtains, it is necessary to use only standard mounting brackets provided by the manufacturer. At the same time, it is necessary to maintain a distance of at least 30 cm from the ceiling or side wall. Failure to comply with this requirement may lead to a decrease in the efficiency of the unit due to obstructed air intake by the unit.
When installing horizontal curtains, it is necessary to select a kit that covers the entire width of the opening, otherwise certain areas of dips in the created drip will be observed.
