High-tech air curtain

High-tech air curtain

The thermal curtain on the front door is a piece of equipment that protects against cold air currents from the street inside the building. The device operates from a powerful fan, which is built into the curtain and creates a high-speed flow of heated air. This contributes to the formation of an invisible obstacle that does not allow warm air to leave the room, and cold vortices to get inside..

Installation and purpose of using the device

The heat fan is set based on the type as well as the type of model. To this end, it is necessary to determine the indicators for the width and height of the doorway, where then such a device and the speed mode of the air flow created by it will be installed. The following rule applies: the lower the location of the opening, the lower the speed should be. The installation of the thermal curtain should be carried out as close to the door as possible due to the fact that the device needs to cover the entire doorway.

The lower the doorway is located, the lower the air flow rate should be.

The lower the doorway is, the lower the air flow rate should be.

It is recommended to mount several curtains with a wide door opening. In this case, the devices will be installed side by side, one after another, and, as a result, a single system will be created that will cover the entire room. The thermal curtain on the front door, the price of which will be increased in this way, guarantees its efficient use. You also need to take into account the speed of the draft that occurs inside the building – this applies mainly to rooms with a large area, which have several doors.

With the correct installation of the heat curtain, the flow of heated air enters the middle of the room even with the doors open, thus providing the room with additional heating

  • Economical in energy consumption. Even taking into account that the device itself is a consumer of electricity, its use is of great benefit. It has been practically proven that the use of an air heating curtain, with its correct selection and installation, makes it possible to save up to 30 percent on energy consumption, which is spent on heating a building in winter and cooling in summer..

This process takes place as follows: warm air masses are lighter than cold ones, in this regard, they rise up, and, as a result, “heavy” cold air accumulates near the floor – thus a gradient is formed. Due to the fact that warm air masses move to the floor from the curtain, the temperature difference in the vertical direction is significantly reduced. As a result, the process of adjusting degrees in the middle position in the rooms in which people are located takes place..

The built-in curtain control system automatically controls the operation of the electric heating device, taking into account the frequency of use of the door. Consequently, the heat curtain will be fully activated when the door starts to rotate. But when the rotation stops, the device will work at reduced speeds, and if there is no need for it, it will turn off altogether (the temperature regime of the institution will correspond to the set norm).

Concealed installation of air curtains

If it is impossible to use an ordinary curtain, the so-called hidden installation method is used. The installation of the device is carried out behind a suspended ceiling, due to which only the lower part with a grate through which warm air flows exit will be visible. Due to this installation method, the equipment becomes almost invisible. The operation of the unit is fully automated, as with a revolving door: when the door is open, it is carried out at full power, in case of non-use – low-speed mode, and when the set temperature is reached – shutdown. This work allows you to achieve an energy-saving mode of consumption of heat and electricity..
