Fire curtains EI60; EI90; EI120 (without irrigation)
Fire resistance limit: 60; 90; 120 minutes (without irrigation with water).
When the alarm is triggered, the curtain is lowered by the Gravigen drive system – without electricity, due to the force of gravity of the lower bar. The lowering speed is 0.15 m / s. In the event of a power failure, the system retains functionality for 72 hours due to the presence of an integrated battery in the control unit.
|Width, max:||6,5 m|
|Height, max:||5 m|
|Box (depth × height):||At a height of less than 4 m 200 × 220 mm||At a height of more than 4 m 300 × 330 mm|
To obtain high resistance at high temperatures, a thin stainless wire is woven into each fiberglass yarn. The inner layer of the fabric consists of thermoactive composite materials, which at 160-180 degrees Celsius expand to 50 mm and provide reliable protection against heat flow.
Fabric canvas is certified as non-flammable and non-toxic.
It consists of three bent, galvanized sheet steel 1.5 mm panels, up to 3 m long. For the construction of long curtains, the panels dock with each other. Both ends of the housing are closed with covers that seal the circuit tightly. The side covers also serve to sense the torque of the tubular motor. The overall dimensions of the box depend on the height of the overlapping opening.
Color execution: any color according to RAL color scale or galvanized steel.

About fire curtains
Fire may occur due to any carelessness, electrical failure, or network congestion. In the event of a sudden occurrence of fire in any commercial, public or industrial building, the main task is to prevent the spread of flame and carbon monoxide throughout its area, threatening the safety of people in it, and also capable of provoking property damage and material assets. And roll fire curtains to minimize harm in the event of an outbreak – one of the most effective means.
These fire safety elements are used to divide the interior spaces into separate segments. They are especially important for large buildings, because on large open areas the fire spreads extremely quickly. Splitting them into separate segments through protective partitions makes it possible to localize the fire, to prevent smoke spread and, as a result, to reduce the possible damage and threat to human lives.
A quality fire curtain – curtains can boast the following advantages:
- Is simple and quick to install;
- Does not violate the organic design of premises and window openings;
- Can be harmoniously integrated in the facade architecture;
- Fire curtains, the price of which varies depending on the manufacturer and other parameters, do not interfere with the habitual operation of the building. In their “assembled” form they are raised to the ceiling and lowered only in case of emergency;
- Enable the integration of light, not thick doors with fire-fighting qualities;
- Can be mounted in tandem with standard gates. This is especially important where there are large congestions and without gates with a special entrance for people simply can not do;
- The fire curtains come into operation only in case of occurrence of fire and reception of a signal from the UPS;
- They reliably localize the burning site, not allowing its products to spread beyond the fenced area for an hour or more. At the same time they provide free access to the infected area to firemen, and also do not interfere with evacuation.
The design of the fire curtain and the principle of its operation
Typically, such products are made in the form of a shaft with a wound web, which is a protective housing made of steel. When the machine starts, the canvas starts to unfold under its own weight, as well as the mass of the cutting part that is at the very bottom, blocking the opening.
The main difference between the curtain varieties lies in the technical characteristics of the materials used for their manufacture. In general, their construction scheme is as follows:
- The basis is a cloth made of heat-resistant fabric, most often glass fiber covered with polyurethane;
- The “control cabinet” becomes an integral element;
- The foundation and guiding fire curtains Moscow have in the form of bent steel structures;
- Necessarily supplied with alternative feeding sources;
- Have in the construction a shaft with a drive;
- Painted with epoxy-polyester composition in any color of the RAL table.
The principle of functioning of such fire-preventing barriers lies in the interaction of thermal sensors, a drive and a system of electromagnets. The latter are connected to thermal sensors, which, in case of ignition, respond to an increase in temperature by sending a signal to the electromagnetic system. Disconnection of electromagnets provokes lowering of the blade.
Varieties of fire protection curtains
Gathering buy fireproof curtains, you should know that they are delineated into two large categories E and EI. The latter includes more robust and fire-resistant structures in comparison with the first, to which the products consisting of one or two layers of specialized fabric belong.
In accordance with the Federal Law No. 123, designed to fill a wide variety of openings, such fire retardants are of several types of fire resistance
- With water irrigation and without it;
- With different fire resistance limits – EI 60, EI 120, EI 180.
Numerical designations are the most important parameters that affect the fire curtains cost. The first letter -E – shows the time of preservation of the whole barrier when the products of combustion are exposed to it. The second letter – I – indicates the time interval at which the protective screen is able to delay the penetration of heat into the room protected by it. They are both measured in minutes. The number in the code says about what minimal time period the canvas can withstand the onslaught of the fiery element.
Fire curtain EI 60 Can be called the most popular option because of a reasonable ratio of quality and product prices. Since the EI 30 fire curtain with a flame retardant limit of 30 minutes does not always allow a safe evacuation and wait for firefighters to arrive. Protective screens with a fire resistance of about 120 and 180 minutes are usually installed together with an irrigation system (usually one-way, with a flow rate of at least 6.8 liters per minute * m2).
Despite the optimal fire resistance of the EI 60 blind, in practice it is often necessary to mount air curtains with a longer protection – EI 90 or even EI 120, which is provided by high-quality products from FireTechnics.
These Fireproof curtains from the manufacturer can be used both independently and together with other elements of the fire safety system of this company. For example, together with smoke curtains and forced ventilation.
