Radiator "Global". Aluminum radiators Global - sectional radiators. Italian aluminum radiators brand Global Radiators global 500 technical specifications

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 heating appliances Global, 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 pass primitive filtering 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 specifications:

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 floor mount, 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 they have a wider range of models, as they are used in many countries of the world, while bimetallic ones are only in the states of the 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, have been reinforced according to 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 heating appliances Global, including sectional bimetal 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 pressure coolant manufacturers have developed a separate type of heating devices, these include 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; it has top part- spherical shape, 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 appearance. Most users leave positive feedback about them, 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.

Now residents of the multi-storey sector are massively changing worn-out heating radiators for new and more advanced appliances, which are full of the domestic market heating equipment. Since 1994, bimetallic radiators from the well-known Italian company GLOBAL DI FARDELLI OTTORINO and C have been in great demand in our country. They receive positive feedback from Russian consumers due to their high mechanical strength, resistance to water hammer, temperature fluctuations, and corrosion. To choose based on a preliminary calculation suitable model from the Global series, it is advisable to study the technical characteristics of the battery you like, find out the average cost, find reviews on the forums.

Externally, the bimetal practically does not differ from the long-known aluminum counterparts. At the same time, bimetallic radiators weigh much more - due to the use of a durable inner steel shell, filled with aluminum alloy on top, which provides good heat transfer. The high reliability of Global radiators is achieved due to the fact that horizontal and vertical tubular collectors are connected by welding and form a single whole. Here are the advantages of this technical solution:

• bimetallic radiators withstand an operating pressure of 30-40 atmospheres (hermetic gaskets also contribute to this);
• it is possible to use antifreezes (acid-base index 6.5-9.5);
• heat dissipation of a section with an interaxal distance of 500 mm - from 170 to 190 W.

Models have two sizes, differing from each other in the level of location of the upper and lower collectors. The difference between the levels is called the center distance: it is 350 or 500 mm.

The Global line includes bimetallic radiators belonging to four main series:

1. Global Style - with a flat top, universal in application, suitable for any window sills;

2. Global Style Plus - have increased dimensions and power;

3. Global Sfera - the upper part of the spherical shape;

4. Global Style Extra - an improved modification of the Style series, which has a classic design and is designed for a pressure of 52 atm.

The table shows the main characteristics popular models bimetallic radiators from Global (dimensions of one section are indicated):

Model	Center distance, mm	Dimensions, mm	Heat carrier volume, dm3	Power, W	Weight, kg
Global Style 350	350	80x80x425	0,18	125	1,6
Global Style Plus 500	500	80x95x575	0,2	185	2,1
Global Style Extra 500	500	80x80x566	0,2	166	1,85
Global Sfera 500	500	80x80x568	0,16	165	1,77

What should the buyer consider?

In an effort to buy bimetallic heating batteries more profitably, you should know that by the combination of materials they are of two types

• "Full bimetal" - it has a supply and discharge collectors made of steel, as well as a vertical connecting tube. The coolant comes into contact only with the steel shell.
• Semi-bimetallic - in them only vertical intrasectional tubes are steel. Wherein aluminum tubes collectors that come into contact with water can be destroyed due to electro-galvanic corrosion.

The basis of all Global bimetallic radiators is a steel frame that completely occupies the entire interior space. The upper aluminum body does not come into contact with the coolant, which increases the durability (and price) of the heater. After the issue is resolved in favor of bimetallic radiators, you should continue to choose according to other criteria and compare the characteristics of different models.

1. Heat dissipation. Thanks to a specially designed ribbed surface, the aluminum shell of the radiators gives off heat well and distributes it, far ahead of aluminum models. The greater the center distance, the higher the heat transfer of the battery. A review of the Global series shows that Style Plus is the most powerful: heat transfer is 10% higher than that of their Global Style counterparts with the same center distance.

2. Number of sections. Owners country cottages first you need to perform a thorough calculation of heat loss through all external structures (walls, ceilings, floors, doors, windows). For housing in standard high-rise buildings, you can carry out a simplified thermal calculation or use an online calculator. If a large-panel house is located in the middle lane, then the number of sections for each room is calculated according to the following scheme:

• determine the area of ​​the room;
• the result is multiplied by 100 W (average standard for specific heat transfer);
• the product is divided by the passport value of the thermal power of one section.

If it is decided to choose a Global Style radiator model with a center distance of 500 mm, the number of sections is found by dividing the area of ​​\u200b\u200bthe room by two. For example, a 10-section battery is enough to heat a room with an area of ​​20 m. To ensure a power reserve, during the calculation, refinement coefficients are used, depending on the number and orientation of windows, the presence of 2 external walls.

3. Design and dimensions. If the niche in the wall is deep and the window sills are large, it is better to buy a model from the Plus line: its depth is 15 mm more than that of Style, there are additional ribs on the sides, higher heat transfer. Sfera modular elements have an elegant rounded shape and a shallow depth. Flat batteries are combined with any interior and save space.

The characteristics are selected in such a way that Global (full bimetal) are ideal option for installation in houses with central heating. However, there are reviews that for the normal performance of functions, before buying, you should find out the parameters of the coolant in the network: if the acidity is above 9.5, then you will have to install cast-iron batteries or look for models with a stainless steel frame.

User opinions

“Almost 6 years ago, during the renovation of an apartment, we decided to change the batteries. A familiar plumber suggested that we buy the Global Style plus 500 model. They have not been disappointed in the choice so far - the stylish appearance, compact size. But, of course, the main advantage of Global is its excellent thermal performance. At full power, sometimes we turn on the radiator, which heats the room with a loggia. The rest of the devices work at half strength, with the help of thermostats we turn down the heat. ”

Ekaterina Gurieva, Moscow.

“I have long heard about Italian radiators manufactured by Global good feedback, but fully appreciated the bimetal only after installation in own apartment(before that we had Chinese batteries). The difference is noticeable: Global heats up instantly, quickly distributes heat around the room, and dries the air less. This winter in our corner apartment it was the first time we didn't turn on the electric radiator: the Global Style handled the heat perfectly."

Andrey, Moscow region.

“As a plumber, I will say a few words about heating radiators manufactured by Global. These batteries do not cause problems during installation: they mounted them on the wall, fastened them with Americans - and that's it. The mounting kit always has a special nipple that allows you to quickly connect the batteries to the system. Customers do not complain about full bimetal: usually such radiators work reliably. And the manufacturer gives a guarantee for 5 years. The only downside is the heavy weight due to the steel frame.”

Eugene, Yekaterinburg.

“In order for the apartment to be warm, it is necessary to choose the right number of sections for bimetallic radiators. The Global model you named has a thermal power of one section of 120 W at an average water temperature of central system+75°. Based on this, a 14-section heating radiator is needed for a room of 17 m2. I advise you to install taps at the inlet and outlet: one - to reduce the flow of coolant (and the temperature in the room), the other - to service the batteries (wash them once every 3-4 years).

Peter, Magnitogorsk.

“We decided to choose the Global Style Extra 300 radiator model, but after installing them in the apartment it became + 22 ° (cast-iron batteries heated the air up to + 22 °). Why is it so cold if there are as many as 10 sections in a room (17 squares)? I'm disappointed".

Maria Streltsova, St. Petersburg.

Price

The more sections turned out in the calculation, the more expensive the heating radiators will cost. But in this situation, it is undesirable to save money: with an excess of heat, you can screw on the tap, and with a shortage, you will have to buy more sections, again pay for delivery and installation. The table shows the average price for 1 section, as well as the cost of 12-section batteries with different heat dissipation.

Radiator brand Global	Heat output of the section	Price for 1 section / cost, rubles
Style 350	125	1100/13 200
Style 500	168	1125/13 500
Plus 350	140	1650/19 800

The Italian company Global has been producing heating radiators since 1971. For almost half a century of history, a small workshop has grown into a large enterprise with its own factory and laboratories. It supplies bimetallic and aluminum radiators to the Russian market.

Global aluminum radiators are presented in a wide range. These are Vox and Vox Extra, Iseo and Klass, VIP, GL and Oscar, all models are able to withstand severe water hammer in a central heating system.

The main advantage of Italian aluminum heating radiators is high heat transfer. Aluminum is an excellent conductor of heat, thanks to which one battery can heat a large room. These radiators also have other features:

• Aesthetics. Batteries will perfectly fit into the interior of a private house or a luxurious city apartment, they will not require the installation of screens.
• Thoughtful design. All models are suitable for installation under window sills and in niches: thanks to the numerous fins, air flows freely between the sections and heats up quickly.
• Versatility. You can use radiators with pipes made of steel, metal-plastic or polymer pipelines. Leaks and other problems are excluded.
• Section structure. Each element is attached to each other with nipples using special three-layer gaskets. The radiator can be reduced or enlarged by adding several sections, making the heating system as efficient and economical as possible.

Italian aluminum radiators - great choice for autonomous heating systems. They are suitable for almost any coolant. Thanks to the reinforced construction, they will last more than 10 years even in a city apartment with centralized heating.

• Installation will not cause difficulties. The sectional structure will allow you to create a radiator of the required length, and there are factory kits for connecting pipelines.

Aluminum Italian batteries - optimal solution for both autonomous and centralized systems in apartments and private houses, industrial, agricultural and commercial buildings.

Clumsy cast-iron batteries, for many years the symbol of Soviet systems heating are gradually becoming a thing of the past. The modern market is ready to offer instead heating devices with a much greater heat transfer potential, and manufacturers specially develop models adapted to Russian conditions(for example, Italian aluminum radiators Global, Fondital, bimetallic Sira and others).

When should you choose aluminum?
Huge speed of heating the air in the room (5 times faster than steel and cast iron batteries) - business card aluminum radiators. In addition, they are famous for their modest dimensions and low weight (the weight of one section without a thermal carrier is less than 1 kg). Due to the small amount of thermal inertia, Global aluminum batteries have a high response rate to changes in the parameters of the control thermostats.

However, it is not always possible to use aluminum radiators. If for private houses in which chemical composition Since the coolant is practically neutral in terms of pH, they are optimal, then in apartments with central heating, where alkaline additives are used in large quantities in boiler rooms, the service life of aluminum is sharply reduced. To neutralize the harmful effects of alkalis, Italian Globals are finished from the inside with an additional protective layer of fluoro-zirconium alloy or polymers, which significantly increases their durability.

There is an opinion that aluminum heating panels are not able to withstand high operating pressure in the network. However, this statement is true only for products made by the extrusion method with the connection of elements using welds. Sectional cast radiators, consisting of individual segments, are made somewhat differently:

Aluminum cast radiators Global easily withstand the working pressure in the network of 1.6 MPa and maximum temperature coolant 110 °C, which exceeds the parameters of the standard characteristics of thermal centralized systems.

Overview of popular radiator models

The indisputable advantage of aluminum radiators is their cheapness, in order to buy Global radiators, you do not have to go to significant material costs. Let's compare the main models that are in demand:

Buyer opinions

Even this brief overview of radiators manufactured by Global allows you to choose the right model for use in a centralized heating system, and for autonomous aluminum radiators - the most best option, which is confirmed by numerous positive reviews about the Global sectional radiators:

“Renovating with my husband private house, reworked the heating, before we had just pipes of large diameter instead of batteries. But ugly: the house was surrounded by all the walls. Yielding to fashion, they wanted to install bimetallic Chinese radiators in the house, but the craftsmen convinced that for our conditions it is best to use the Italian company Global. To be honest, global warming has already arrived for us! It’s always warm at home, and we also installed special taps that regulate the temperature and now we can maintain a comfortable mode in every room: lower in the bedroom, warmer in the kitchen.”

On the Russian market radiators from the Italian company Global Radiatori are very popular due to their high quality and large assortment. The products of this manufacturer are designed taking into account the specifics of domestic heating systems. The most popular are aluminum sections Global Vox and bimetallic "Global-Style" (these radiators are very popular today).

Types of radiators

Heating radiators "Global" are produced in three varieties:

• bimetallic;
• aluminum;
• extrusion.

All types of products have their own characteristics, technical characteristics, advantages and disadvantages, which will be discussed in more detail in the article.

Bimetal radiators

Reliable, high quality bimetallic radiators "Global" are the standard of quality. They are made from strong and durable materials. Products model range Style is best radiators heating. In them, the part in direct contact with water is made of steel, and the outer part is made of aluminum.

Bimetallic radiators "Global" are designed for operation in systems with high operating pressure (up to 35 atmospheres) and can be installed both in central and autonomous heating systems. The most basic advantage of this series is the thermostat, which is installed in the structure. It contributes to almost instantaneous provision of comfortable air temperature for staying in the room. Bimetallic radiators, the price of which is about 850-900 rubles per section, are resistant to aggressive environments and corrosion, and also have high thermal conductivity. They are double-colored with heat-resistant compounds, which ensures their resistance to mechanical damage.

Features of bimetallic radiators "Style 500" and "Style Plus"

Bimetallic radiator 500 "Global" (series "Style") is made in It has a flat top, its height is 57.5 cm, depth - 8 cm, center distance - 50 cm, weight - 1.97 kg. The heat transfer of such a section is 168 watts. This heating element can be used with various types pipes (metal-plastic, copper, polypropylene). The radiator "Global-Style" 500 consists of separate parts. The sectional assembly system using nipples allows you to increase or decrease the number of sections.

Radiator "Global-Style Plus" has collectors of simple shapes without pockets, in which the formation of air pockets is excluded. tubes between them large sizes, which makes it possible to work with contaminated coolants. The design of the model makes it possible to increase thermal power through the top air chamber. Heating elements of the Style Plus brand are manufactured with center distance parameters of 350 and 500 mm. For these bimetallic radiators, the price is approximately 10,100-10,200 rubles for 12 sections.

Advantages of bimetallic radiators

Bimetallic radiators from the manufacturer Global have a lot of advantages.

1. Ease of installation. Sections can be removed or added during installation.
2. Excellent thermal conductivity. Due to aluminum, which has good heat-conducting properties, radiators have a high heat transfer rate. The coolant temperature can reach up to 120-135 ºС.
3. Strength. All products at the factory are tested by pressure testing at 52.5 atmospheres.
4. Long service life. This indicator is provided thanks to quality materials used in production.
5. Resistance to mechanical damage. The outer surface of the radiators is covered with powder enamel, which protects it from scratches and abrasions.
6. Resistance to aggressive environment. Inner part radiators is made of high-strength steel, which is resistant to acids.
7. Attractive design. The fade-resistant white color is well suited to a variety of interiors.

Extrusion Radiators

Extrusion heating radiators "Global" Oskar are designed for vertical mounting. This type of product is distinguished by its original design, which consists of separate parts interconnected by sealing Teflon rings and adhesive-sealant. The radiators are light in weight and have an exclusive design.

The manufacturer produces types of sections with different center distances - 100, 1200, 1400, 1600, 1800 and 2000 mm. This type of radiator requires certain characteristics of water, which is a coolant. The hydrogen index should be at least 7-8 units, and water filtration from heavy elements is also necessary. This model has a high heat dissipation, but is inferior in strength, which does not allow it to be used in harsh working conditions.

Differences between bimetallic sections and aluminum radiators

Radiators differ from each other in production technology and material of manufacture. In addition, they have different working and maximum pressure. This indicator is important when installing sections in multi-storey buildings with central heating, where high blood pressure in the pipeline of the system. Aluminum radiators use one metal completely, while bimetal radiators use high-quality steel inside and aluminum outside. It is very important to consider that an aluminum radiator is not suitable for installation if the heating system consists of copper pipes or the boiler has a copper heat exchanger.

Features of installation and operation of aluminum radiators

Because in autonomous heating the operating pressure of the coolant is low, then reliable and inexpensive aluminum radiators "Global" are well suited here. Their installation does not differ from the installation of bimetallic sections, but there are some recommendations from the manufacturer that should be followed.

1. Radiators consisting of ten sections or more must be connected diagonally to the system, which makes it possible to increase their efficiency by 10%.
2. It is not recommended to install decorative elements on the front of the heating equipment. This contributes to a decrease in the level of heat transfer of radiators.
3. Heating devices that have ten or more sections should be mounted on additional brackets.
4. The operational life of the equipment also depends on the quality of care for it. To do this, before the start and during the season, the surface of the sections should be systematically cleaned from dust and dirt.
5. Humidifiers made of porous materials should not be installed on radiators. This can lead to water leakage, which will eventually damage the paintwork of the sections.
6. If the system is not going to be used in winter, it must be drained of water. AT summer time it is desirable that the sections are completely filled.
7. It is not recommended to self-paint the surface of aluminum sections, this reduces their effectiveness.
8. Do not use different chemical additives or impurities that artificially increase the temperature of the coolant.

The efficiency and durability of "Global" radiators, first of all, depends on the indicators of the heating system. Each type of sections is designed for certain parameters of working conditions, and their installation must comply with all the manufacturer's requirements specified in the technical data sheet.
