The equipment items are:
- A heating element,
- Nozzle,
- Electric motor,
- Fan.
The functions of the heating element are performed by a two-pass heat exchanger. It is created from copper pipes, which are equipped with plate-like aluminum fins. Through the pipes that come out of the housing, water is supplied to the heat exchanger.
Its connection to the heating network is realized using flexible corrugated pipes. IN winter period possible shutdown hot water. Therefore, the devices provide water drainage. The water thermal curtain, if installed correctly, is free from corrosion. Its body is made of special materials. The insulation of internal elements is also made from special materials.
Operating principle
The equipment uses air flow, which is warmed by thermal energy coming from the heat exchanger. Electricity is consumed only to rotate the fan and comes from a 220 V network.
The blowing of thermal curtains and heating (partial, maximum) depend on the operation of the fan. The water heat curtain is controlled using a remote control.

When cold outside air enters a heated room, several significant problems are created at once. Firstly, heating costs increase sharply, as they say, heating the street. Secondly, these sensations are far from pleasant, which can also lead to deterioration of health. Such problems can be solved by installing a thermal curtain; it will create a reliable barrier to cold air.
Depending on the heat source used, air-heat curtains are divided into electric and water. The latter are distinguished by their efficiency, using hot water from central heating as a heating element. These devices have become widespread due to several advantages:
- protecting the room from cold air and heat loss;
- protecting people indoors from drafts;
- additional heating of the room in winter;
- maintaining cool conditioned air in summer;
- additional barrier against dust, insects, exhaust gases from the outside;
- low costs of use, unlike electric thermal curtains.
Operating principle and installation of water thermal curtains
The principle of operation of the device is as follows: the fan inside the device creates a high-speed air flow, as a result of which warm air does not leave the room, and outside air does not penetrate it. The heat source of such an air curtain is hot water from the central heating system.
The installation of this unit requires large financial and physical costs, but all this pays off in full later due to low costs and high power. Devices of this type can most often be found in industrial enterprises, but they are also indispensable in other commercial premises or Catering with a large flow of visitors.
Installation is carried out directly in the area of the entrance door: horizontal curtains - above the door, vertical curtains - on the side of the entrance opening. Please note that the vertical curtain should not be shorter in length than the height of the doorway.
The main element of a water thermal curtain
Such an element is radial fan, creating the necessary high-speed air flow. Such a single turbine should be located along the entire length of the thermal curtain. The fan creates a uniform air flow, and its motor is mounted on the side of the device.
But there are units with an engine in the center, and turbines located on the side of it. The reason for this may be high price manufacturing turbines over 70 cm in length. Of course, such simplified curtain designs cost several times less, but do they bring the required effect? Indeed, in the central part of such a device there is no required high-speed air flow, and this leads to a decrease in the main protective function thermal curtain.
Water curtain control type
For a water heat curtain there must be at least two switches: for the fan and the heating element. Additionally, two- or three-stage heating power regulators, a switch to the second fan speed, and a thermostat for maintaining the set temperature can also be installed.
Control of the device depends on the selected model. There is a mechanical control built into the air curtain body, as well as control using a remote control. However, the first option is used only on small models intended for installation on door and window openings standard sizes. This situation is easily explained: the buttons on the body can only be reached at arm's length, and high-power water curtains installed, for example, in warehouses and workshops, are more convenient to control from the remote control.
It is very convenient to use a limit switch in the design of the curtain. It activates the thermal curtain only when the gate or door is open. This device is also good for its economical use.
Criteria for choosing a thermal curtain
When choosing a water curtain, you need to pay attention to the following parameters:
- length of the device;
- curtain power;
- device performance.
- installation method;
- type of device control.
Device performance affects speed air flow air, and accordingly affects the maximum installation height. In order to save money, you should not buy a water curtain with a lower capacity than necessary. Incorrectly selected curtains will not bring the desired effect.
Power is also the main parameter when choosing a thermal curtain, especially if the device’s function includes heating the room by heating the air. On average, to heat a room of 10 m², you need a device with a power of 1 kW. But it should be clarified that the air at the outlet of the thermal curtain will never be hot, since heating elements have high speed blowing
Curtain length different models and manufacturers there are 60-200 cm. For standard doorways Models with a length of 80-100 cm are well suited. In general, the choice of the length of the water curtain depends on the width of the opening: either equal to it or slightly larger. This rule must be observed so that the air flow of the curtain can completely block access to outside air.

Water thermal curtains produced by the Teplomash company are modern compact equipment with a water heat source, which is installed above door and gate openings to provide mixing and shutter protection of openings. Thermal curtains with a water heat source are designed for effective protection premises from cold street air. In addition, they can significantly reduce heating costs, since damper curtains cut off and heat cold air from the street, while mixing curtains only heat cold street air before supplying it to the room.
Design features and advantages of water curtains
Air curtains "Teplomash" are fully factory-ready products. Almost all Teplomash air curtains can be installed both horizontally and vertically. Curtains are produced in different lengths, but if the door or gateway is wider or higher than the length of the curtain, you can put several curtains in a row.
The water horizontal thermal curtain is fixed on a durable ceiling structure threaded rods or on the wall - using the included brackets. To ensure maximum performance, it is essential to ensure correct location curtains in relation to the doorway. Obstacles in the path of air flow from the curtain significantly reduce its efficiency.
A water-heated thermal curtain installed vertically on one or both sides of the doorway is attached using standard brackets directly to the wall or to the floor on a special bracket.
Thanks to the use of hot water as a coolant, a water thermal curtain for the front door is economical. In addition, the curtain allows:
- keep the front door open, which is important for shops;
- create an air barrier that prevents cold street air;
- heat cold air from the street before supplying it to the room;
- have a beneficial effect on human health, protecting the opening from the penetration of dust and insects;
- keep cool in hot weather in air-conditioned rooms by protecting the opening with a flow of cold air without heating.

A water thermal curtain is one of the types of climate control equipment designed to maintain a certain temperature in a room by preventing the leakage of warm air to the outside and cutting off cold outside air. This is a kind of thermal barrier that separates the room and the outside space with a flat stream of air, which is supplied under pressure.
Equipment that creates a thermal barrier is intended for installation in the plane of a door or gateway in places with a large flow of people: in industrial workshops, public and residential buildings, shopping centers, warehouses, restaurants.
How does a water heat system work?
The principle of operation is quite simple: a radial fan directs an air flow onto the opening - a kind of barrier through which warm air cannot leave the room, and the cold one cannot penetrate inside.
The fan turbine is located along the entire device - this ensures efficiency and a uniform supply of hot air that is pumped through the body. The air movement pattern is as follows: cold air is taken from the floor, blown through the heating circuit and released as a hot stream parallel to the plane of the doors or gates.
The engine is attached to the side. If the length of the turbine exceeds 0.8 m, then the engine is located in the central part, and additional small turbines are installed on the sides.
The cut-off curtain heats up as air passes through the water heater. The water curtain requires central heating or a hot water supply to operate.
The fully assembled design looks like this:
- heat exchange mechanism;
- control system (electronic);
- fan;
- frame;
- guide blinds;
- brackets;
- side covers and covers.
Classification
The water thermal curtain can be presented in various models intended for use in buildings with certain conditions. Equipment is classified according to different characteristics, including:
- by purpose: general, for car washes;
- by air flow: small, medium, large;
- by location: vertical, horizontal;
- By geometric parameters: according to the cross-section of the body - round, elliptical, rectangular, others; The structure of the nozzles is semicircular and straight.
Control
The water curtains are controlled by two switches, which can be mechanical or electrified.
The fan - which can be two-speed - and the heating elements are switched separately. The control system can be equipped with additional 2 (3)-stage heating power regulators. If the fan is two-speed, then its speed is also regulated by the remote control.
If a thermostat is installed, the equipment may automatically turn off when the set temperature value is reached.
The control panel, depending on the model, has the following varieties:
- built-in – for small curtains that are installed above doors or window openings in small rooms;
- wired – in large rooms where control of the built-in button is difficult, and the remote control can be placed in a convenient place.
In warehouses and hangars, limit switches are used, which bring the system into operation only if the door or gate is open.
Unique advantages of the system
Water thermal curtains have such design features that give them a number of advantages over electric heating devices:
- Less energy consumption with equal heat transfer. Cost savings can reach 30%.
- Possibility of installation in case of technical difficulties: insufficient power of the electrical network, large opening height (up to 12 meters).
- Convenient Maintenance, due to the simplicity of the design.
- Maintaining a stable temperature in the room and equalizing the temperature difference in the ceiling area and at the level of human growth - this makes it more comfortable for people to stay in the room and creates favorable conditions for storing any goods.
- Neutralization of drafts, which leads to a reduction in the risk of colds.
- Protection against the entry of insects, small animals, and dust into the building.
- Can be used as an air conditioner if the coolant circulation system is turned off.
The water curtain creates additional convenience at car service stations, car washes, checkpoints and public catering points, since thanks to it Entrance door can always remain open. In addition, it not only creates insulating protection, but also serves as a heater for the warehouse vestibule.
The scope of its application depends on the functionality of the equipment: from air screening of warehouses and hangars to preserving the interior of an office or shopping center from street dust.
Selecting a water thermal curtain
Water curtains are needed, first of all, for air isolation of the interior of the room from the outside air. Productivity, that is, efficiency, is what it is main characteristic equipment.
There are other important criteria that you need to pay attention to when choosing a particular model:
- type of room;
- is there a vestibule;
- what are the usual weather conditions?
- for what purpose is the veil purchased;
- desired type of installation;
- control method;
- dimensions (length) of the device necessary for high-quality closing of the opening;
- what power is needed - this factor is most important if it is necessary to heat the room;
- performance, affecting air flow speed and unit height.
Thermal curtain market
The most famous companies on the Russian market are:
- “Ballu” (international holding) – products with minimal energy consumption. Among the models: horizontal BHC-H20-W45, BHC-H10-W18; vertical: Stella BHC-D25-W45, StellaBHC-D20-W35.
- “Frico” (Sweden) - excellent design, excellent quality, versatility, but high cost. Model options: AR3515W, ADCSV25WL.
- "Tropic Line" ( domestic brand) – functional and efficient equipment for reasonable prices. However, only a few models (for example, X432W, X540W) are industrial water devices, the rest are household ones.
- Teplomash (Russian manufacturer) - the products are reliable, easy to use, and the cost is affordable.
Serial Russian models "Teplomash"
As an example, we can take a closer look at the thermal power of serial models Russian manufacturer- Teplomash company:
- . Here are the 100 series (opening: 1–2.5 m), KEV - P114E and P115E - with ceramic heaters with PTC self-regulating effect and thermostats.
- Medium power. In that model range you can see the series: 200 (opening: 2–2.5 m); 300 (3–3.5 m) and ceiling series 300 (built into a suspended ceiling).
- Interior. The 600 Series is available in elegant vertical columns and horizontal elliptical or segmental illuminated options.
- Industrial thermal. Series 400 (opening: 3–5 m); series 500 (up to 6 m).
Heavy-duty designs - water thermal curtain series 700 for openings up to 12 meters high. Usually made to order for special equipment (hangars for airplanes and helicopters).
Installation of models of these series can be either vertical or horizontal – on the side of the door or gate. If necessary, it can be installed on both sides of the opening.
In all designs, the shell provides a degree of protection - IP-21 (from vertical drops and large particles). If the room is dominated by high humidity, then upon request the degree of protection IP-54 can be provided (for some models).
Installation
Installation of a water heat curtain is labor-intensive and requires the involvement of a specialized company - this will provide warranty service and subsequent services.
The costs required to install the equipment are fully recouped during operation due to high power, efficient work and low maintenance overhead.
There are 3 ways to position the system:
- Horizontal installation - above the door or gate opening.
- Vertical installation - on the side of the entrance opening.
- Hidden installation - placement of a built-in unit behind suspended ceiling elements with the cut-off flow output through air supply grilles.
The height of vertical water thermal curtains must be at least ¾ of the height of the heated opening.
Horizontal curtains must cover the entire width of the opening. Failure to comply with this rule will result in a failure in the air barrier.
To mount the system, only standard brackets recommended by the manufacturer may be used. Distance from the surface (at horizontal installation– from the ceiling, for vertical – from the wall) must be at least 0.3 m. Otherwise, air intake by the equipment will be difficult, which will lead to a decrease in productivity.
The equipment is connected to the central heating or hot water supply system using quick-release parts. If necessary, due to the type of insulated room, install a pump that increases air circulation to enhance heat transfer.
Thanks to the generation of an air insulating barrier, water curtains create a special microclimate in premises for various purposes: from offices to warehouses and hangars. Such structures require energy costs, but overall energy consumption is reduced by protecting the building from freezing. Water thermal curtains can be considered an optimized energy source, working by circulating hot water in common system heating.
