Italian radiators Global have gained recognition due to their reliability and unsurpassed technical characteristics. Like all Italian heating equipment, they have a long service life, their design is carefully thought out. What are batteries from this well-known manufacturer? We will talk about this in our review. We will tell:

• about the design features of Global radiators;
• about model ranges and their differences;
• about the pros and cons of radiators;
• about technical characteristics;
• about popular models.

Finally, we will publish user reviews of these Italian radiators.

Technical characteristics of radiators "Global"

The Global brand and its products were introduced in 1971. Thanks to the extensive experience and continuous improvement of assembly technologies, the radiators of this Italian brand have become known all over the world. Today this brand is one of the leaders in the heating market. In 1994, the manufacturer enters the Russian market and is rapidly mastering it. Since then, Global radiators have become even more reliable and perfect.

In our country, central heating does not differ in the quality of the coolant and the stability of pressure, for which, of course, Global batteries are prepared.

Development and modernization technological processes for the manufacture of high-strength radiators, purely Russian operating conditions of heating equipment contributed. It's no secret that domestic central heating systems are characterized by unstable pressure and disgusting quality of the coolant. This is what made it possible to create equipment that can work in the most adverse conditions.

Subsequently, Global bimetallic radiators appear on the market, which are resistant to water hammer, high pressure, high temperatures and aggressive coolant. Thanks to this, the products of the Italian brand have earned positive ratings from Russian consumers - today Global devices are installed in tens of thousands of houses and apartments.

Model lines

The following series of radiators are presented on the heating equipment market:

• bimetallic radiators Global Style Extra;
• bimetallic radiators Global Style Plus;
• aluminum radiators ISEO;
• aluminum radiators VOX.

Let's take a look at these models in more detail.

Bimetal Radiators Global

The Global Style Extra series differs from the Global Style Plus series in dimensions. One section of Style Extra radiators has dimensions of 415x81x80 mm for models with a center distance of 350 mm and 565x81x80 mm for models with a center distance of 500 mm. As for the Style Plus radiator section, it has dimensions of 425x80x95 mm for models with a center distance of 350 mm and 575x80x95 mm for models with a center distance of 500 mm.

Technical characteristics of both model ranges - working pressure 35 atm, crimping pressure 52.5 atm, maximum coolant temperature +110 degrees, connection diameter ½ or ¾ inch. The heat dissipation of Style Extra radiators is 171 W for models with a center distance of 500 mm and 120 W for models with a center distance of 350 mm. The Style Plus output is 185W for models with 500mm center distance and 140W for models with 350mm center distance.

If a small depth of radiators is important to you, choose the lineup Style extra. Want to get maximum heat output? Then take a look at the Style Plus lineup. The price per section varies between 1000-1100 rubles.

Global bimetal radiators are made of high-strength steel and aluminum. Their sections are interconnected using paronite gaskets - this ensures that there are no leaks. The aluminum "jacket" is created by high pressure casting, which ensures excellent heat transfer from steel to aluminum. The aluminum itself is coated with a double layer of paint - thereby achieving increased coating strength.

Aluminum radiators Global

Aluminum batteries from the Italian brand Global are distinguished by their resistance to poor coolant. For this they have a special fluorine-zirconium coating. It provides alkali and acid resistance, protecting Global batteries from penetrating corrosion. The maximum pressure in the heating system must not exceed 16 atm (test pressure is 24 atm). Maximum temperature coolant is +110 degrees. The permissible pH of the coolant varies in the range of 6.5-8.5.

As in the case of bimetallic models, the coloring of aluminum radiators "Global" during production is carried out in two stages. Center distance is from 300 to 800 mm. Due to their technical characteristics, aluminum batteries quickly warm up the premises and react no less quickly to changes in the temperature of the coolant.

Aluminum radiators "Global" will be a reliable solution for heating private households. IN high-rise buildings it is best to use bimetallic batteries.

The Aluminum ISEO range includes basic models with center distances of 350 and 500 mm. Radiators with a center distance of 350 mm have dimensions of 432x80x80 mm, their heat transfer is 134 W per section. Models with a center distance of 500 mm have dimensions of 582x80x80 mm, heat dissipation is 181 watts. Devices from the Aluminum VOX model range are thicker - models with a center distance of 350 mm have dimensions of 440x80x95 mm, heat dissipation is 145 watts. Batteries with a center distance of 500 mm have dimensions of 590x80x95 mm and a heat dissipation of 195 watts.

All parameters are specified for one section. Connection diameter for Global aluminum radiators is ½ or ¾ inch. The price per section varies between 770-800 rubles.

Advantages and disadvantages of Global batteries

Italian radiators have a number of important advantages:

Internal metal pipes Global devices resist high pressure, and the aluminum jacket gives off heat excellently.

• high quality of metals used for their development;
• resistance to low quality coolant;
• high heat dissipation - up to 195 W, depending on the center distance;
• high-quality two-stage painting;
• reliable protection against leaks;
• resistance to high pressure;
• compliance with all Russian and European norms and standards.

Not without some drawbacks:

• despite the presence of corrosion protection, Global aluminum radiators cannot be used in centralized heating systems;
• high price - On sale you can find cheaper models that are in no way inferior in quality.

Despite this, Global radiators continue to hold leadership in the heating market.

By going to the official website of Global, you can find information about the places where their products are sold. All licenses and certificates for manufactured products are also presented there.

Popular models of radiators "Global"

Global ISEO 500 is the most purchased product of the Global brand.

Among the most popular models, we can highlight the Global ISEO 500 radiators made of aluminum. The center distance of this model is 500 mm, the type of connection is lateral, the design is wall-mounted. The heated area, depending on the number of sections, ranges from 1.8 to 36 square meters. m. The volume of one section is 0.44 liters, the maximum temperature of the coolant is up to +110 degrees.

Bimetallic models used in multi-storey buildings are in the greatest demand. The most popular model is the Global Style Plus 500 with a center distance of 500 mm. The maximum heated area is 37 sq. m, the maximum temperature of the coolant is up to +110 degrees, the type of connections is lateral, the internal volume of one section is only 0.19 liters.

The third model in the list of popular ones is Global Style Extra R 500. These are bimetallic radiators with a center distance of 500 mm, with side connection and wall construction. The maximum heated area for these devices is 34.2 sq. m. The internal volume of one section is 0.21 liters, the maximum temperature of the coolant is up to +110 degrees.

The Italian company "GLOBAL DI FARDELLI OTTORINO and C" has been producing radiators since 1971. Production facilities are located in the province of Bergamo in the city of Rogno. Approximately 40% of production is consumed in the domestic market. The rest is distributed throughout Europe.

In 1994, the company entered the Russian market. Specific conditions - low quality of the coolant and unstable pressure - forced the specialists of the enterprise to specially develop new models of heating devices. So there were bimetallic radiators Global Style, aluminum Klass and ISEO, other brands were modified specifically for the conditions of Russia.

Global Style range and technology features

The production of the following heating devices of the following types and brands has been mastered:

Global is an Italian company, and production is also located in Italy

• Aluminum:
  • ISEO
  • class
  • VIP R
  • MIX R
• Extrusion Radiators:
  • OSCAR
  • Ekos Plus
• Fully bimetallic radiators:
  • style
  • Style Extra
  • Style Plus
• JUNIOR towel warmers

The painting of all heaters is two-stage: first, a layer of paint is applied and fixed, and a protective varnish coating is applied on top. This technology allows you to maintain the original appearance for a long time, and the surfaces also tolerate contact with detergents well. The manufacturer recommends periodic cleaning of dust with soapy solutions (dust greatly reduces heat transfer and is also harmful to health). The use of abrasive or chemically active substances is prohibited.

Aluminum radiators Global

Featured on Russian market models of aluminum radiators "Global" have a reinforced design. Models launched earlier in production were specially changed for operating conditions in central heating networks. These modifications have the letter "R" in the designation. It is available on all molds for casting these models, therefore it is present on each section. Models Style, KLASS and ISEO do not have such letters, as they were immediately developed with a reinforced structure.

All models are produced by injection molding. As a result, the sections are reliable, can be operated at pressures up to 16 atm (in individual heating usually 1.5-3 atm, in a centralized - 6-7 atm).

The difference between the models is mainly the depth of the section, the number of air duct ribs and their shape. The main indicator of efficiency, heat transfer, depends on these parameters. For convenience, the parameters are summarized in a table.

Table of technical characteristics of aluminum radiators Global (click to enlarge the image)

Here are the most popular sizes, but in almost all models there are options with a center distance of up to 800 mm. But they are usually made to order. But you need to take into account that the models with a height of 600, 700 and 800 mm, as well as GL / D are a product for the European market. Their working pressure is 10 atm, test - 16 atm. Therefore, such modifications should be used in high-rise buildings with caution, and nothing threatens them in individual heating.

Of the features of operation: the manufacturer does not recommend shutting off the coolant unnecessarily. This leads to acceleration of corrosion processes. To adjust the temperature setting is recommended.

Extrusion Radiators

These thermal devices are made by a different method. Part of the radiator with plates is made by extrusion: it is not cast, as described above, but squeezed out, giving it a given shape. The resulting panels are pressed or glued to the cast headers. This option, of course, has a much lower operating pressure, thinner walls, less weight, and less heat transfer. For our networks, extrusion radiators are very poorly adapted. They can only be used in individual heating: working pressure - 9 atm. The main argument in their favor is the low price. Light weight can be considered as a positive quality: not all walls can be hung with a high structure heavy weight. Then extruded aluminum radiators from Global are the perfect solution. But for normal operation, stable pressure is required. They are also more demanding on the quality of the coolant: pH is strictly within 7-8.

If you choose from two models Global OSCAR or Global Ekos Plus, then they are more suitable for our OSCAR conditions. They have welded vertical and horizontal manifolds, which provides greater reliability compared to similar devices from other manufacturers. They also have a large thickness of pipes (noticeable by weight).

What are bimetal radiators

Everyone knows what aluminum radiators are. But here, they may not know. Outwardly, there are no differences: the forms are very similar. Aluminum is lighter in weight. And it's all because of the design. Global bimetal batteries are made of welded steel tubes around which aluminum alloy ribs are cast. The supply and return manifolds are made of steel, as well as a vertical tube connecting them. All this is welded into a single design. The resulting combined radiator section has the advantages of both metals: the strength and corrosion resistance of steel, and the good heat dissipation of aluminum.

What are the advantages of such a solution:

• high strength and sufficiently high working pressure - up to 30 atm;
• the possibility of using with antifreezes - pH 6.5-9.5;
• high heat transfer - 170-185 W from one section with a center distance of 500 mm.

This combination of characteristics allows the use of Global bimetallic radiators in multi-storey buildings with central heating systems. But for normal operation, it is necessary to clarify the parameters of the coolant in your network: if the pH is higher, either install cast iron, or look for modifications with a stainless steel frame (there are some).

Bimetal radiators "Global Style": specifications

As can be seen from the table, the most powerful is the Global Style Plus radiator. Increased heat transfer is achieved by increasing the depth (95mm instead of 80mm) and additional side fins. Global Style Extra and just Style have a slightly lower heat transfer, but the depth of these models is less. They are suitable if the window sill or a niche of small depth.

The requirements are clear and not excessive. It's not that hard to follow them. And the devices themselves have very good reviews.

Radiators "Global" reviews

“The batteries were changed in 2008. We installed Italian Global Style 500 - four radiators with ten sections and one with six sections. Included was detailed instructions about the radiator itself and how to install it. Installed by a specialist, I helped. For seven years of operation there were no problems. What I don’t like very much: it takes a long time to bleed air through the Mayevsky tap. There are no more comments. The products are of very high quality. I recommend."

Sergey, Rostov-on-Don

“I never would have thought that the shape of a radiator could have a strong effect on the heat in a room. But it turned out that it was. We installed Global Style 500 bimetallic radiators four years ago, and it became much warmer. From it comes a tangible flow of heat. Although they say that there is no need to put them in private houses, we have them. Never regretted. The feedback is definitely positive.”

Elistina, Moscow

“I installed aluminum Global. Very pleased with the quality. They've been working for three years and never had any problems."

“I installed a Global Style 500. It sucks. Of the twelve sections, only the first two are warm.

“The three-year operation of Global aluminum batteries has eliminated all doubts about the quality. The product is really good.”

The range of heating radiators on the modern market is able to amaze any imagination. A huge number of manufacturers, models and forms of heating devices makes their choice very difficult. However, there are not so many truly high-quality products. These can be safely attributed to Italian-made Global radiators. In this article, we will review the products of this well-known brand.

General characteristics of Global radiators

First of all, it should be noted that all Global heaters supplied to the post-Soviet countries are adapted by the manufacturer to our difficult operating conditions. This is especially true for centralized heat supply networks, where pressure surges and the degree of contamination of the coolant can be very different.

But even if we take the individual systems of private houses, then not every owner is engaged in cleaning and water treatment before filling his heating network. Sometimes tap water does not go through primitive filtration and is sent to the system in its original form. A self-respecting manufacturer has no choice but to adapt to these conditions. As a result, Global heaters received the following technical characteristics:

Specifications of Global Radiators

Each section of the Global batteries is completed with connecting nipples and paronite gaskets. In addition to the assembled product, the manufacturer encloses a bracket for radiators of a suitable design or a floor mount, a manual air release valve and end caps.

Model range of aluminum radiators

In this context, the word "aluminum" does not mean at all that the device is made of pure aluminum, which does not occur in nature. Global sectional batteries are made of aluminum alloy, which includes elements such as silicon (up to 12%), copper (2.5%) and iron (up to 1%). Other metals are also present in smaller fractions in the alloy. Such a composition retains the excellent thermal conductivity properties of aluminum and at the same time gives the material strength, corrosion resistance and ductility for high-quality castings.

Traditionally, aluminum radiators for heating have a wider range of models, as they are used in many countries of the world, while bimetallic ones are only in states former USSR. The following series of batteries are currently available for purchase:

• class;
• ISEO.

Note. The production of sectional radiators Global Iseo and Klass was launched quite recently, so these products are considered new.

All models of batteries with a center distance of 350 and 500 mm supplied to the CIS countries were strengthened using a special technology, due to which their working pressure was 16 bar. The remaining products with a height of 600, 700 and 800 mm are not modernized and are designed for a pressure of 10 bar, this must be taken into account when purchasing. Reinforced models can be distinguished by the designation, the Latin R is added to it, for example, the Global VOX R 500 aluminum radiator. The same letter is stamped on each section near the upper manifold. This does not apply to the latest innovations - Iseo and Klass, they were hardened from the very beginning.

The listed series of heaters differ in the shape, number and size of the vertical ribs responsible for the heat transfer of the battery. There are no more fundamental differences, the connecting threads of the nipples are standard - 1 inch. The table below shows the dimensions of all models of aluminum radiators and the heat transfer values ​​of 1 section:

Important. The heat transfer values ​​of each section presented in the table are correct, provided that the difference between the average temperature of the coolant and the air in the room is 70 ° C. That is, in reality, it is at least 1.5 times less, which must also be taken into account when selecting batteries. In addition, the heat flow varies slightly depending on the number of sections assembled together. For example, 1 battery of 8 sections will give less heat than 2 devices of 4 sections.

All Global heaters, including sectional bimetallic radiators, have a protective internal coating, which is applied using a special technology. Its task is to protect the material from corrosion for as long as possible. Thanks to this, even aluminum batteries can function for a long time and reliably in centralized heating networks. True, it is not recommended to install them in apartments of high-rise buildings, since there may not be enough margin for the working pressure for which the radiator is designed.

Model range of bimetallic radiators

To work in centralized networks with high coolant pressure, manufacturers have developed a separate type of heating devices, including the Global bimetallic radiator. As the name implies, the elements of its construction are made of 2 metals - steel and aluminum alloy.

A strong internal frame is made from steel pipes by welding, through which the coolant flows. Outside, the frame is covered with aluminum alloy fins, which allows to maintain the effective heat transfer of the battery. The following models of bimetallic devices are sold under the Global brand:

• TYLE;
• STYLE PLUS;
• STYLE EXTRA;
• SOLO;
• SFERA.

One of the most popular is Global Style Plus radiators, their frame is made of steel pipe 38 x 3 mm (horizontal manifold) and 16 x 2 mm (vertical tubes). Due to this, the price of the product is significantly higher than that of aluminum batteries with the same characteristics.

But the device will function normally in any adverse conditions, even defrosting will not overcome it immediately. The table of dimensional and thermal characteristics of batteries is presented below:

Otherwise, the differences between the models are purely in the configuration of the fins, or even simply in the form of sections. For example, the Global Extra radiator has the same number of fins as the Style, only it looks more streamlined on the outside. The Global Sfera model boasts an even more rounded shape, its upper part is spherical, hence the name.

Conclusion

Global Italian radiators are an excellent solution for any home, they stand out not only for their high quality, but also for their stylish design. appearance. Most users leave about them positive reviews, there are practically no complaints. So that you do not have them, you need to choose the right number of sections and type of battery for your heating system.

Radiators Global are products of the Italian company GLOBAL Radiatori, one of the well-known manufacturers since 1971. The products meet high quality standards, which contributes to the continuous expansion in the global market. Radiators are available in two types: aluminum and bimetallic. Let us consider in more detail the features of the radiators of this company, their model range, advantages, disadvantages, technical characteristics, as well as installation and operation features in modern conditions.

Bimetal Radiators Global

These radiators are specially designed for harsh climates. The radiator has inner part made of steel, which gives high strength and allows avoid corrosion. The outer layer is made of aluminum, and this provides high heat dissipation. The design of the radiators prevents the formation air locks. Can withstand pressure surges up to 40 atmospheres. Service life up to 20 years. Installation is carried out in systems autonomous heating and in apartment buildings with central heating. Consist of sections. The number of sections affects the power of the radiator: the more sections, the more power. Economical, functional. Comfort heating mode.

Of the models of bimetallic radiators Global, the following can be distinguished:

Models of aluminum and bimetallic radiators Global also have two standard sizes, differing in center distance of 300 mm and 500 mm.

Having considered the list of Global radiator models, you can see some Advantages and disadvantages.

High-tech alloys are used in the production of these radiators, which guarantees long service life. Sections allow you to change the length of the radiators required for this space. The advantages include modern design, build quality, ease of installation, high heat dissipation. Bimetallic radiators can be installed in buildings with an individual heating system and in multi-storey buildings with central heating. Aluminum radiators Not recommended for central heating system, since the aluminum inner layer can be destroyed by the chemicals that are contained in the water. Global aluminum radiators are best installed in private homes. The chemical compatibility of the heat transfer medium must be observed.

There are other manufacturers of radiators on the market. There are manufacturers that have a lower price compared to the price of Global radiators. GLOBAL Radiatory has extensive experience in the field of innovative development of radiators, which allows us to work on new modifications.

For example, intercollector channel the Global radiators are wider than those of the same Sira Group radiators, resulting in fewer blockages.

You can also find an abundance of *bad* Chinese copies of bimetallic radiators from another Italian manufacturer Viertex. In order not to find yourself in such a situation, it is necessary to always require a certificate when buying radiators.

The cost of Global radiators depends on model, center distance and number of sections. To heat an area of ​​1.5 - 2 m², one section is taken, but it is necessary to take into account the choice of a model with the required technical characteristics. Thus, it is possible to calculate the number of sections for the area of ​​the required room.

The cost of one section aluminum radiator Global can vary from 390 to 520 rubles. The cost of one section bimetal radiator is from 650 to 750 rubles.
