Energy saving is an important issue in winter, when you have to pay a lot for heating. This is especially true for commercial structures, since it becomes necessary to heat large rooms. It is not always possible to save resources, but their greatest consumption falls on frosty and windy weather. 
Doors in shops, workshops, warehouses are often opened, due to which cold masses penetrate into the room. To prevent this process, use electric thermal curtains. The device directs the flow of heated air perpendicular to the draft coming from the street and prevents its movement inside the building.
Air curtains are not connected to ventilation systems. This device works separately. The movement of the heated stream helps to keep warm air in the room. Anyone can install an air curtain, for this it is unnecessary to contact the designers - it is enough to choose the right device and install it in the doorway. An incorrectly selected device will not be able to fully perform the function assigned to it, allowing cold air to enter the room. Consider all the nuances so that the purchase justifies the funds invested in it.
The principle of operation of the thermal curtain
The device is powered by electricity. The basis of the device is a case in which the following are installed:
- heating elements;
- fans;
- engines;
- electrical circuit.
When the equipment is turned on, the fan motors start to work, due to which a directed air flow is formed. Its temperature depends on the power of the heating elements. It should be sufficient to prevent cold air from entering. Thermal curtains can be installed in different positions relative to the doorway.
Installation is allowed:
- horizontally;
- vertically;
- combined.
It can be mounted both on the wall and on the ceiling.
Recommendations for the selection of devices
You need to purchase air curtains in a store specializing in the sale of heating equipment. It is important to take into account the performance of the electric heat curtain, so that the flow of warm air is sufficient to cut off the penetrating cold masses. In rooms where there is a vestibule, devices of low power can be installed at the entrance.
Installing a limit switch on the door helps to save heat and reduce energy consumption. In this case, the heat curtain will only work when needed. That is, when the doors are opened, a sensor will be triggered, which will launch into the device and turn it off after they are closed.
When choosing a thermal curtain, consider:
- the height and width of the opening;
- the length of the jet that is supplied from the body;
- network voltage: 220 or 380 V;
- device performance;
- operating conditions, including the temperature regime that must be maintained indoors, as well as weather factors typical for the region.
The calculation of the parameters should be carried out by a specialist so that the purchase justifies the funds invested in it.
