Global

The Global brand was founded in 1971 by the Fardelli brothers. At the beginning of its activity, the company produced only aluminum radiators. In 1994, the company successfully began to conquer the Russian market and then, they had to start producing bimetallic batteries as well. Equipment manufactured by Global meets Russian GOSTs.

Modern radiators manufactured by a company from Italy are made of high quality materials. Inside are steel vertical and horizontal tubes. The outer part of the radiator is aluminum, which indicates high strength.

Ferroli

Of the Italian manufacturing companies, Ferroli, which is steadily developing, should also be mentioned.

Ferroli aluminum radiators

Ferroli POL aluminum radiators have a high thermal output.

Ferroli radiators are very convenient thanks to the following points:

  1. Slow change in temperature gradient (slight temperature difference at different heights, which are between the ceiling and the floor).
  2. Proper location of batteries in a horizontal version (installation under the window and along the walls facing the outside, in order to reduce the negative effect of the cold that comes from windows and external walls).
  3. Attractive appearance and a large selection of models.
  4. Durable and high quality.

You can also pay attention to the German heating radiators.

As you can see, Italian radiator manufacturers offer a wide range of radiators and are leaders in the production of aluminum and bimetallic batteries. Especially on the market there are products of a large number of manufacturers from Italy.

Sira is a model of efficiency and beauty

Features of Italian batteries

The Sira heating radiator, being one of the best representatives of bimetallic radiators, organically combines the advantages of a steel core and an aluminum heat exchanger.

Overview of heating radiators "Sira"

Benefits of Sira batteries

Thanks to the use of two materials, Sira batteries are distinguished by the following features:

  1. The presence of an all-metal frame completely eliminates the contact of the coolant with aluminum, so that the latter is protected from corrosion, which, as a rule, is caused by a bad coolant.
  2. The use of high-quality materials and constant control of the production process significantly increase the life of the radiator compared to similar products from other manufacturers.
  3. The special shape of the heat exchanger increases the power of the panel.One section of the radiator allows you to heat a large area of ​​​​the room, so you can use smaller radiators (or fewer sections).

But the main advantage of Sira radiators is their elegant and attractive appearance. Their characteristic curved body without sharp edges and protruding corners will not disappoint even the most demanding customer.

In addition, they can be installed in children's and other similar institutions where security issues are given increased attention.

Advantages of Italian heating panels:

  • innovative design and smooth outer surface - batteries do not accumulate dust and are easy to clean with common household detergents;
  • low inertia - after a minimum period of time after switching on, the air in the room will warm up to a comfortable temperature;
  • strength - the radiator perfectly withstands high pressure inside the system (up to 170 atmospheres) and tolerates hydraulic and pneumatic shocks well;
  • long period of operation - the absence of welds, which are often destroyed, allows the manufacturer to guarantee a 20-year period of operation of their products;
  • the highest quality technology for assembling individual sections - unique patented O-Ring gaskets are used;
  • noiselessness - during thermal expansion, the steel frame does not make noise and crackles.

Aluminum radiators Sira

Aluminum heaters are produced according to two technologies: casting and extrusion. Cast modifications are more massive and reliable: they do not have seams, but their price is higher - more metal is consumed, the technology and equipment itself are more expensive. Extrusion is made from several parts: the central part with ribs and air ducts is squeezed out, giving them a given shape. Then it is pressed, welded or glued to the collectors. This design is less reliable - there are seams, the collector walls are thinner. But less metal is consumed, and radiators cost less. Often recycled aluminum is also used in this technology, which also reduces the price.

What are the best aluminum radiators? Of course, cast. But with a very limited budget, extrusion can also be used. They will work well with a small stable pressure and good quality of the coolant, that is, in individual heating.

Cast aluminum radiators

Overview of heating radiators "Sira"

Some models of die-cast aluminum radiators: Sira Ali Princess, Ali Queen, Ali Royal

The company provides a 15-year guarantee for all heating devices of this group. Outwardly, they are slightly different: there are a different number of air ducts, the shape changes. But in any case, there are no sharp corners. Sira cast radiators can be used in heating systems with high and low temperatures, from alternative energy and heat sources. They have a low inertia, because the heating of the room occurs in a matter of minutes after the system is turned on. A small amount of water in the radiators also makes it possible to maintain the required temperature level in the room with high accuracy (it is possible to install radiator regulators).

Technical characteristics of Sira aluminum radiators are summarized in the table. Collector diameter - one inch, working pressure - 16 atm

Please note that when installing, each radiator must have a manual or automatic air vent valve.

Some models of extruded aluminum radiators: Sira ALUX, Rovall, Swing

Despite the shortcomings of the technology itself, Sira gives this type of product the same great warranty: 15 years. For 50 years, considerable experience has been accumulated, technologies have been worked out. At the factory, all radiators undergo two-stage testing. Apparently, the technology used is advanced, since the working pressure of this group exceeds that of those made by casting: 25 atm, versus 16 atm.

Innovation and Design

Onice's design and technology are the result of years of research and innovation, seeking new solutions for living spaces. The appearance of the Onice is a benchmark for the entire industry, representing one of the most modern examples of Italian style in industrial design. Its exclusive lines, fluid and dynamic, make it suitable for any space, making it the perfect piece of furniture for the most modern and prestigious environments.

The electronic display of a new ergonomic concept has been designed to provide the best possible intuitive use, together with comprehensive temperature management and usage schedule. Its locking system provides additional security for the elderly and children, who are thus insured against the possible consequences of incorrectly set parameters.

Connecting the Sira battery

The Italian company produces not only heating devices, but also components that are necessary for installation. Sections of the radiators are connected at the factory, so the device is provided with high-quality tightness. If there is a leak, you will have to buy a repair kit.

For the correct installation of heating radiators, it is necessary to take into account some recommendations:

  1. In order to remove the radiator during repairs without turning off all the heating system, it is necessary to install shut-off valves for each device.
  2. The hanging bracket can only be installed in a horizontal plane. The deviation can only be allowed by 0.1 degrees. If there are large discrepancies, then the heat transfer of the device will decrease. It is impossible to fix the radiator close to the wall.The distance between the appliance and the wall must be at least 3 to 10 cm for air movement.
  3. The thermostat must be installed separately for each device. The control valve must be installed on the heat carrier supply pipe. You can fix it on the radiator using a special adapter.
  4. In the RS series, the lower connection is made using a special connection block. In addition, a duct extension is installed at the same time. Sufficient circulation of the heat carrier and uniform heating of all sections of the radiator is carried out thanks to the unit. If you install a radiator with more than 10 sections, then you need to lengthen the duct.
  5. After the radiator is connected to the heating system, it is necessary to screw the plugs onto the device. In the traditional model of the radiator in the case, you can see 4 holes for connection. After the battery is installed, 2 inlet channels remain. The most optimal solution would be to connect Mayevsky's automatic faucet to the upper hole of each radiator in order to remove excess air from the system.
  6. Sections can only be connected in production. With self-connection, the radiator will fail in further operation. But employees of a company that has a manufacturer's license can perform a technical connection. If the work was carried out by a specialized company, then the guarantee for the radiator remains unchanged.

Radiators

It is difficult to imagine a modern house or apartment without heating radiators. They allow you to comfortably spend time in your home in the frosty season. At the same time, their appearance should match the style of the interior.This fact determines the popularity of acquiring bimetallic radiators.

Among the many variations, Sira bimetallic heating radiators are the most acceptable in terms of price-quality ratio. At the same time, many buyers note that the installation does not require the possession of special skills.

Overview of heating radiators "Sira"

The Sira RS radiator is ideal for introducing metal radiators after the old cast iron ones. The installed elements will last a long time and, if properly installed, will not require replacement and technical repairs until the next overhaul.

The most common combination for a bimetallic radiator is steel and aluminum.

The ability to use the desired metal in “problem” places in a greater proportion increases the strength characteristics of the future room heater. Each millimeter of the battery is calculated and manufactured precisely and scrupulously, so there can be no doubt about the quality and durability.

Overview of the range of bimetallic radiators

Radiators of the Bimetal line have a two-layer structure. The basis is a steel core, which is a connection of collectors and channels through which the coolant moves. Welded joints are made according to the technologies used in the aviation and aerospace industries. The outer shell is aluminum alloy.

The layers are interconnected in a patented way. Models successfully combine the resistance of steel to corrosion and the high heat transfer of aluminum.

Hybrid radiators have a bimetallic composition. Their difference lies in the fact that they have 2 alternative connection options: from the mains or from the heating system.

Bimetal devices are assembled from separate parts - sections.The tightness of the joints is ensured by special gaskets.

A few years after entering the heating market, Sira becomes known in many other countries, delivering quality and durable radiators. Further improvement of assembly technologies has made it possible to achieve impressive results, thanks to which the products of this Italian brand are becoming known almost all over the world.

What are the main features of Sira bimetallic radiators?

  • Resistance to high pressure - this gives them the ability to work in centralized heating systems.
  • Adaptation to Russian working conditions - the manufacturer has done everything possible so that his products can work even in the most severe conditions.
  • High quality workmanship - it was achieved through careful control over the technological processes of production.

Overview of heating radiators "Sira"

Bimetal models are excellent Italian quality!

Sira devices are made from environmentally friendly components, which allows you to achieve high quality finished products. These Italian radiators are used to heat apartments, offices and workrooms, clinics and hospitals, kindergartens and schools, as well as industrial and industrial premises. They tolerate water hammer well, cope with increased pressure in heating systems, and resist the effects of aggressive coolant.

Bimetallic batteries can boast such an advantage as a high heating rate - in this parameter they easily bypass competitors. One of the factors affecting the speed is the small internal volume. It should also be noted that the Sira bimetallic heating radiators are resistant to leakage - high-strength gaskets located between the individual sections are responsible for this.

Radiators "Sira" are made of steel and aluminum - such a "sandwich" of two metals allows you to achieve resistance to negative influences. The production of aluminum "shirts" in some models is carried out using extrusion. Due to this, exact dimensional conformity and resistance to destruction are achieved. As a result, very durable and reliable bimetallic batteries of true Italian quality are born.

The main guarantee of the strength of Sira bimetallic batteries is the use of high-strength steel, from which the internal cores are made - they are responsible for resistance to pressure and corrosion.

Also on the market are aluminum Sira models - they will be useful for heating private houses as part of autonomous heating systems. The devices are distinguished by a long service life, good appearance and a large margin of safety.

Extrusion batteries brand "Sira"

The Aluminum line is manufactured by extrusion. With this method, the aluminum melt is squeezed out using a special machine (extruder) through the molding holes.

The group is represented by two models: Rubino and Alice+. Thanks to the extrusion technology, the heaters can be placed vertically and reach two meters in height.Batteries are inferior in strength to bimetal and aluminum casting.

Characteristics of radiators:

  • operating pressure - up to 16 bar;
  • manufacturer's warranty - 25 years;
  • coolant temperature - 110 °C.

The Rubino model is made in a restrained style. It has a wide range of sizes: from 0.2 to 2 meters. The number of sections is offered to choose from - from 2 to 10. Cost - from 600 rubles per section.
