Enterprises and organizations that, taking into account the specifics of their activity, must keep access to the building permanently open, need to install an air barrier at the entrances. The purpose of such a barrier is to preserve the conditions of the internal space from the influence of external factors.
Vertical and horizontal thermal curtains, without obstructing the passage of visitors, significantly reduce heat loss, and also limit the penetration of dust, small insects, exhaust gases and unpleasant odors into the room.
Types of devices
The air curtain consists of a durable plastic or metal body, a heating element, a centrifugal fan and a baffle (nozzle). A feature of these devices is the type of heat source:
- electric They are equipped with tenams (tubular electric heaters) of different lengths and power. Electric curtains are characterized by ease of installation and a large temperature range;
- water They have a heat exchanger that requires a complex connection to the central heating system, but the costs of installing the equipment quickly pay off due to low operating costs;
- without heating These designs do not have a heating element, they serve as air barriers for the penetration of mosquitoes, dust, and also cut off the outside air in refrigerating chambers, warehouses and other rooms.
All modern devices are equipped with filters that clean the air flow passing through the device, and a safety system that prevents overheating of the device and short circuit.
Mounting methods
Manufacturers of air-conditioning equipment provide various options for placing air barriers in doorways of any size and type. All devices can be divided into several groups according to the installation method:
- horizontal thermal curtains. They are fixed above the entrance doors of the building. By installing several devices close to each other, you can create a continuous air flow for a wide entrance;
- vertical devices. Mounted on the sides of the doorway. For maximum efficiency, curtains are placed on both sides;
- embedded models. They are used when there are suspended ceilings. The devices are located behind a special panel with a decorative grid.
The model range of mechanisms presented in online stores allows you to choose devices that best meet the most diverse parameters and requirements of enterprises.
Devices for work in difficult conditions
For premises in which carpets are washed or motor vehicles are serviced, it is recommended to use special ones heat curtains for car washes. Splash-proof devices have an anti-corrosion case made of galvanized steel and stainless steel screens, which allows them to withstand high droplet humidity and the presence of chemical elements in air flows. The specialists of the company engaged in the implementation and installation of air-conditioning equipment will be able to determine the degree of protection required for a particular consumer.
Special parameters
When choosing an air-heat device optimally suitable for a certain commercial or industrial object, you need to pay special attention to the characteristics that affect the efficiency of the curtain:
- razmer — the width of the device;
- productivity — the volume of air masses passing over a certain time period;
- heat output power — regulates heat loss;
- availability of additional functions — anti-corrosion coating, automatic control, etc.;
- degree of safety;
- compliance with the interior of the room.
Taking into account all these parameters when selecting an air heat curtain will significantly increase the energy efficiency of the device, eliminate breakdowns and extend its service life as much as possible.
