principle of operation and design of the KEV air curtain
Working structure thermal device is not complex. The "box" of the device is a structure made of sheet steel with polymer coated, inside which heaters, a fan, a nozzle are located. The fan draws air from the space, the heating device raises its temperature and outputs it at an angle or directly through a special channel with an air flow into the opening space.
The main condition is the span of the jet, which must be no less than the space along which the thermal curtain is fixed.
In some situations, you may need more advanced thermal protection. In such cases, several thermal devices are installed in a row, which makes it possible to create an efficient system.
To date, air heaters are electric, water or gas. Usually electric curtains used to protect against cold spaces small size, and in large industrial workshops, it is advisable to use gas or water heaters.

Appointment of curtains
Air curtains for openings are an energy-saving element of heating and ventilation systems for buildings of all types and purposes. Teplomash KEV-12P604E are curtains of the "mixing" type, they do not create resistance to the rushing cold air, they simply dilute the cold stream with warm jets, raising its temperature to the required one.
Curtain device
Curtain Teplomash KEV-12P604E has a body made of sheet steel with a high-quality polymer coating. Inside the case there is an air heater, a fan, a nozzle for the jet exit. The fan sucks in air from the room, the air flow is heated in the air heater and is ejected through the nozzle in the form of a jet in the opening plane or at an angle to it.
As a rule, the jet flowing out of the curtain should have a span equal to the width or height of the opening. Therefore, the most important of overall dimensions veil is its length. If the size of the side of the opening, along which the curtain is installed, is greater than the length of the curtain, then several adjacent curtains are arranged in a row, overlapping the side of the opening with a total length.
Curtain fans
Teplomash KEV-12P604E air curtains use cross-flow-fan fans. Long Working wheel of such a fan is located along the air curtain body. This makes it possible to organize air intake and its supply to the nozzle, which is uniform along the length of the curtain, which contributes to proper formation flowing from the curtain of a barrage jet.
The blades of the impellers are directed not along the generatrix of the cylinder, but at a slight angle to it. This softens the "shock" interaction of the blades with the tongue of the fan during rotation of the wheel and reduces the noise level.
Thermal protection of curtains
Curtains with an electric heat source are equipped with a device emergency shutdown heating elements in case of case overheating. Overheating can occur for the following reasons:
- the entrance and exit windows of the air curtain are cluttered with foreign objects (or heavily soiled)
- the fan has failed
- the thermal power of the air curtain greatly exceeds the heat loss of the room in which it operates (for example, in a small vestibule)
Curtain painting The body parts of Teplomash KEV-12P604E air curtains are protected from the outside and from the inside with a high-quality polymer coating. Thermal resistance of the coating is 180°С.
Operating conditions for curtains with an electric heat source and curtains without a heat source:
- ambient air temperature - +20...+40°С
- relative air humidity at a temperature of 20°С no more than 80%
- the content of dust and other impurities in the air is not more than 10 g/m3
- the presence of drop moisture in the air, substances aggressive to carbon steels (acids, alkalis), sticky and combustible substances, as well as fibrous materials (resins, technical fibers) are not allowed
Specifications
The KEV thermal curtain helps to preserve the microclimate of office, retail, warehouse, service or industrial sites. And according to the manufacturer, KEV climate control units will save not only the microclimate, but also the wallet of the owner of the office, warehouse or workshop. After all, the thermal curtains of this trademark consume electricity much more carefully than devices created by competing companies.
How does the KEV air curtain work?
The preservation of the climate of the room protected by the curtain is carried out due to the generation of an air "barrier" - a jet of warm air blown out of the nozzle of the air conditioning unit. Such a "barrier" blocks the door, gate or window opening, preventing contact external environment and heated space. That is, cold air does not come into contact with the microclimate of the office, warehouse or workshop.
As a result, the temperature inside the protected room equalizes, the humidity level stabilizes, and heating costs decrease. In addition, the air barrier cuts off dust and exhaust gases, prevents the penetration of insects and partially traps odors.
How electric thermal curtains KEV are arranged
Climatic installations of this type are designed on the basis of a thermal convector circuit. That is, the main structural elements The air curtains are a body, a heating element and a turbine driven by an electric motor.
Both the turbine and the heating element are located inside the case, and the engine is mounted from the side (or bottom / top) side. The design of the housing and the layout of internal and external units is determined by the installation scheme of the air curtain, which can be hung over the opening ( horizontal version) or mounted on a wall or floor, on the side of a gate, door or window (vertical mounting). In addition, depending on the installation scheme, a nozzle is equipped on the lower or side face of the body - a narrow slot through which warm air. Jet positioning air curtain carried out with the help of external pads mounted on the housing nozzle.
As heating element curtains use tubular electric heaters or radiators connected to a water or steam heating system. Moreover, thermal curtains with electric heaters are easy to install, but expensive to operate. But "water" or "steam" curtains are famous for their cheap operation, but they will require professional installation, with a possible restructuring of the heating system.
The air curtain turbine is designed as a radial fan. Its dimensions, as well as the characteristics of the engine, are selected based on the performance (volume of air mass pumped per hour) and the thermal power of the air conditioning unit.
How to choose a curtain?
As a rule, curtains are selected according to the dimensions of the protected opening. Moreover, the geometry of the gates, doors or windows must comply with and performance characteristics(thermal power and performance) of the air conditioner and its dimensions. After all, the curtain still needs to be mounted.
Therefore, the installation housing must fit into the dimensions of the lintel or the distance from the edge of the opening to the wall. And the performance characteristics must correspond to the area of the gates, doors or windows protected by the curtain.
Moreover, in order not to immerse our readers in the intricacies of engineering calculations that determine the identity of power and heat losses, we recommend paying attention to the data indicated in the passport of the thermal curtain. After all, most manufacturers indicate the maximum dimensions of the opening that the curtain being sold will protect.
Therefore, the best selection criterion is the passport of the thermal curtain.
The range of industrial thermal curtains brand "KEV"
Far from the entire assortment of the KEV brand can be included in the segment of industrial climatic equipment. Only air conditioning equipment with an installation height of 3 meters, powered by a three-phase (industrial) power supply. Only some models of the Teplomash company fit these criteria, namely:

However, vertical installation is also possible, when a 2-meter opening is blocked with the help of KEV-12P3041E. The air curtain can be powered only from a three-phase network (380-400V). Among other advantages, it should be noted the possibility remote control with this model, a two-circuit structure of the heating element, which allows switching between 12 and 6 kW of thermal power, and the ability to work only on blowing, without heating. In a word, KEV-12P3041E is a highly productive and economically profitable option thermal curtain. The price of this model is 18-25 thousand rubles.
- . This installation is mounted only in a horizontal position, blocking the opening up to 3.5 meters high. Moreover, the electric heat generator KEV-9P2020E facilitates the process of installation and maintenance to a level that provides for a minimum qualification of performers. However, ease of installation does not detract from the performance of this model. Curtain Teplomash KEV-9P2020E generates 4.5-9 kW (at one and two stages of the heating circuit), pumping up to 1.5 thousand cubic meters of air per hour. Another plus of this model is water resistance. Therefore, the KEV-9P2020E air curtain can be mounted not only in a warehouse, but also in a car wash. The cost of this curtain is 13-18 thousand rubles.
- Thermal curtain Teplomash KEV-6P2221E . This model can be connected both to a household network and to an industrial line. However, the height of the opening protected by this curtain is only 2.5 m. Therefore, the KEV-6P2221E model should be attributed only to the “semi-professional” segment of the Teplomash assortment. However, the power of this installation is 6 kW, and the productivity is 1.6 thousand m3/hour. That is, for 12-19 thousand rubles you can purchase a curtain with quite "industrial" performance characteristics.
