Italian aluminum radiators - why are they the best on the market today?

Italian heating radiators. Choosing a leader

Italy is a confident world leader in the production of heating systems. Their scope is wide enough - from central, typical for city apartments and office premises, to one-pipe, used in private houses. Italian heating radiators have long gained a reputation for quality and reliability.

Among their significant advantages is the price. Compared to products from the UK or Germany, Italy heating radiators benefit. The ratio of cost and quality of the Italian systems is ideal. And the service life is more than two decades. The developers take into account both possible pressure drops in boiler rooms and the quality of the coolant. Product design is also not overlooked.

One of the brands that have proven themselves in the Russian market is the Ferrolli company. A small workshop for the production of gas boilers appeared in the Italian city of San Bonifacio almost 60 years ago. It was founded by Dante Ferroli. Today Ferrolli includes a whole group of companies that produce not only heating systems. The brand has been known in Russia since 94.

In the same year, another Italian brand, Global, appeared on the domestic plumbing market. Aluminum radiators have proved themselves worthy in the harsh conditions of Russian realities - with unstable pressure and unstable coolant indicators. Thanks to this, the production of equipment for Russia was established.

The rise of the company was rapid from the very beginning. The brand, founded in 71 by the Fardelli brothers, has produced more than 20 thousand radiators in its first year of operation. Today, Global's production volumes are disproportionately higher.

The Italian company Sira is also trusted by Russian consumers. The principle of production of radiators of this brand is similar to the Global technology. Bimetallic systems have a strong steel core. At the same time, the heat transfer of devices is close to that of those made of aluminum.

It is to the specialists of the Sira brand that the world owes the appearance of aluminum radiators. The first unit appeared just a few years after the company was founded. To this day, the brand maintains its leading position in the production of aluminum heating systems.

User opinions

“Heating radiators from Italy are really of high quality, but for this it is not necessary to buy expensive and well-known brands. We took not very well-known Viertex bimetallic batteries to the dacha and are very satisfied. Their internal volume is small, so that the water circulates better, and the rooms warm up faster. At the same time, I think that they cost us quite inexpensively - about 400 rubles. " “Instead of leaking cast iron, I took Global Style Plus for the whole apartment - in terms of reliability, bimetallic Italian batteries are no worse, but they warm up faster and look neater. While I was picking up sectional radiators, I revised many models, but these seemed more solid and thick-walled. We worked for one winter and fully met my expectations. "
Anton, Nizhny Novgorod.

“I put it at my own risk and peril by Sira Gladiator (not personally, of course). The boiler room in the area is old, but here, although not a complete bimetal, the characteristics are still quite good. As a result, we survived the first winter without leaks, in warmth, and most importantly, they saved money and bought a good thing. " “I am surprised that Radena is more often counterfeited by more famous brands. How many I have already come across them in clearly non-native packaging, once I even saw them with a curve stamping of Rosstandart.Therefore, here the choice must be approached very carefully. I installed such aluminum radiators for myself 8 years ago - they still do not flow ”.

Italian heating radiators Fondital

Italian aluminum radiators from Fondital are made by casting. The line is represented by a large number of positions:

• EXCLUSIVO B3;
• EXPERTO A3;
• CALIDOR80 B2;
• ALUSTAL;
• CALIDOR SUPER B4;
• CALIDOR SUPER and many others.

Radiator depth can be 77 mm and 97 mm, section width is 80 mm as standard. The center distance is 350, 500, 600, 700 and 800 mm. To increase the heat transfer of the battery, manufacturers make a second hole on the back wall, add the number of fins, select their location in such a way as to improve convection.

The batteries are painted in two passes. The first time by the method of anaphoresis, and the second time by the method of spraying powder enamel.

The paint does not break off and reliably protects the material from various mechanical damages. All Fondital heat exchangers withstand an operating pressure of 16 atmospheres - although the indicator is not the highest, but this value is enough for all autonomous heating systems and most centralized ones. The larger the section, the higher its thermal power.

Calgoni - Made in Italy

Italian aluminum heating radiators from Calgoni are premium heat exchangers. The line is represented by two positions Alpha and Alpha Pro. The difference lies in the depth of the section. The Alpha is 85mm and the Alpha Pro is 96mm. Accordingly, the thermal power also differs - 190 W and 210 W, respectively.

Calgoni batteries are painted in two layers, the painting method is the same as for Fondital heat exchangers. The main characteristics of Calgoni radiators:

• center distance 500 mm;
• maximum working pressure 20 atmospheres;
• test pressure 25 atmospheres;
• permissible coolant temperature 110 degrees.

The heat exchanger is connected to the heating circuit with inch pipes. During installation, a Mayevsky crane must be screwed into the upper end. The sections are delivered from the factory in packs of 10 pieces, and in the retail network you can buy the required number of sections.

Two options for thermal insulation of the facade with mineral wool: wet facade technology and installation on the lathing. The cost of both methods is approximately the same.

Italian firm Global

Italian aluminum heating radiators are more expensive than domestic ones due to their production by casting. Thanks to this, the appearance of the product is better, the corners and surfaces are smooth, the geometry is perfect. The Global brand is no exception, the line of aluminum heat exchangers of which (Aluminum) is represented by two positions - ISEO and VOX. The cost of the section is from 780 rubles.

ISEO heat exchangers are available in two versions with a center distance of 350 and 500 mm. The depth of the ISEO-350 section is 95 mm, and the ISEO-500 section is 80 mm. Both products can withstand 16 atmospheres. The inner surfaces are protected by a fluorine-zirconium layer, which makes the heat exchanger less demanding on the quality of the heat carrier. This was done on purpose in order to optimize the product for Russian conditions. An interesting article: "Which radiators are better for autonomous and centralized heating systems and why?"

Global VOX battery specifications:

• center distance 350 and 500 mm;
• depth 95 mm;
• maximum pressure 16 atmospheres, test 24 atmospheres;
• coolant temperature 110 degrees.

The connections for connecting to the heating circuit are located in the front part (side connection).

Ferroli aluminum radiators

Like all Italian aluminum radiators, Ferroli heat exchangers are made by casting, painted in two ways and assembled on metal nipples with a protective inner coating. The ruler is represented by three positions, which are marked with numbers (3, 5, 5/80).

The only difference is in size:

• 3 - center distance 350 mm, depth 98 mm, dimensions 431.5 / 80 mm;
• 5 - center distance 500 mm, depth 98 mm, dimensions 581, 5/80 mm;
• 5/80 - distance between axles 500 mm, depth 80, dimensions 581.5 / 80 mm.

The working pressure for all is the same 16 atmospheres, the test pressure is standard 24 atmospheres.The battery is connected with inch pipes to a common circuit. The product is quite standard, therefore, the quality, like all Italian sanitary ware, is at its best.

High-quality insulation of the facade of the house with modern materials will reduce heat loss and thereby save on heating.

Rifar aluminum radiators - modern adaptation of proven developments

The young Russian manufacturer deservedly got into this rating. It doesn't have many products yet, but judging by the reviews, the company is moving in the right direction. And here we present one of the best radiators of this brand.

Rifar Alum Series

The Alum line is designed specifically for individual heating systems. Its main feature is the ability to use different heat carriers - water, special fluid and even oil! The series is presented in two standard sizes, with a center distance of 350 and 500 mm. Radiators are produced with the number of sections from 4 to 14. The section has a size of 90/81 mm, the weight of one section does not exceed 1 and 1.42 kg, respectively, and the nominal heat transfer is declared at 137 W for radiators with a center distance of 350 mm and 186 W for radiators with center distance of 500 mm. And this despite the fact that the volume of the coolant is only 0.19 and 0.27 liters!

Such a high value of efficiency is due to the peculiarity of the shape of the internal section of the vertical channels, as well as the large area and specificity of the configuration of the ribs. Another plus is the high speed of movement of the coolant, due to which the intensity of the formation of deposits on the inner walls is reduced.

SIRA - the largest Italian aluminum radiators

Italian aluminum heating radiators from SIRA are produced in two ways: casting and extrusion. Cast heat exchangers are presented in 12 positions, which differ from each other in design. The range of dimensions is different for each model, although the values ​​are standard. So, the center distance can be 350, 500, 600, 700 and 800 mm. The height of the heat exchanger with an equal distance between the axes for different models may differ slightly due to design features.

Another difference in the depth of the section is 75, 80, 90, 95, 96, 97 mm. At the same time, the section width remains standard for all models and is 80 mm. Radiators withstand a working pressure of 16 atmospheres. There is only one color available - white. 15-year warranty.

SIRA batteries manufactured by the extrusion method are presented in two positions:

• Rubino;
• Alice +.

The peculiarity of this line is that the height of the heat exchanger can reach two meters. The center distance of Rubino varies from 200 to 2000 mm in 100 mm increments. Alice + is available only in large sizes with an axis distance from 900 to 2000 mm in 200 mm increments. The depth is standard for all 100 mm. All radiators of this model range withstand 25 atmospheres and are sold in blocks from 2 to 6 sections.

Domestic aluminum radiators

Russian aluminum radiators are also of interest to buyers. They are produced on modern imported equipment, have good characteristics and affordable prices.

Rifar

Rifar Alum Ventil Battery
This series of radiators is manufactured under license from the Italian company Global, whose products we have already reviewed. Aluminum products are represented by the Alum and Alum Ventil models. Let's briefly describe their characteristics:

• Special design of the vertical channel - no welding required;
• Working pressure up to 20 atmospheres;
• The ability to use antifreeze;
• Heat dissipation 183 W;
• Section price 410 rubles;
• 10-year warranty, 25-year service life.

Despite the fact that Rifar radiators are manufactured in Russia, the requirements for the hydrogen index (pH) are quite stringent - 7-8. At the same time, the passport clearly states that it is prohibited to use a coolant with other parameters.

So if you are not sure about the quality of your system, it is better to choose something else.

Thermal

An inexpensive radiator with a working pressure of up to 20 atmospheres and good pH values ​​- from 7 to 9, a good flow pattern and a protective coating that protects against corrosion. Its sections are only 60 mm thick, so it will easily fit into a small niche. Due to this, the heat transfer of the section is not very high - 167 W, but the price cannot but rejoice - only 250 rubles. per section.

Italian heating radiators

Italian radiators are one of the best batteries for heating a home. Italian manufacturers, like no one else, tried to adapt their products to the climatic conditions of all of Europe, as well as for operation in the harsh Russian climate, therefore such heating batteries - bimetallic, fancy cast iron, steel or aluminum - are always a welcome acquisition that for a foreign that for the domestic consumer. Italian heating radiators made of aluminum are made taking into account the increased aggressiveness of the heat carrier (both physical and electrochemical) and the hydraulic instability of our, especially central, heat supply complexes.

Configuring the inner surface of the Italian aluminum heating radiator also prevents dirt build-up due to poor cleaning of the circulating heat carrier. The coating of the outer surface of the device is made according to an innovative, resistant to external manifestations, technology - two-layer staining of sections with enamel in different ways (the first is by the anaphoresis method, the second is by spraying). Bimetallic Italian heating radiators have a solid steel core, but at the same time, their heat output is at the level of aluminum batteries. They behave well in central heating systems, where water hammers and abrupt changes in water pressure in residential pipelines often occur. The configuration of Italian heating radiators with an aluminum heating surface allows the bimetal battery to fit perfectly into any interior style. For each type of Italian heating radiators, you need to know their functional parameters and operational nuances. Therefore, when choosing the optimal battery, you need to be guided by the following nuances: power; availability of heating battery certification. For centralized heating complexes, cast iron and steel tubular Italian heating radiators will do. and have very good performance characteristics. A big plus of cast iron batteries is resistance to heat carriers with increased aggressiveness (for example, due to pollution). However, the appearance of such radiators often leaves much to be desired, which significantly limits the scope of their application. Cast iron Italian heating radiators are standard - power, dimensions and connection methods. However, special attention should be paid to the possibility of adding sections. You cannot always do this yourself. In such cases, radiators with the required number of sections are ordered directly from the manufacturer.

Buy Italian heating radiators In Rostov-on-Don, Krasnodar at a good price it is very simple: make an order by phone or e-mail.

Perfect enamel coating of Italian radiators is one of the attractive factors for Russian consumers

Their coating on Italian devices is made using modern special technology. To give additional strength and resistance to all sorts of external influences, the technology of two-layer painting of sections is used. First, anophoresis is done - when the battery is immersed in a bath and washed with a paint solution; then the powder enamel is sprayed onto the surface.

Tips for choosing a radiator

As we can see, the price of Italian aluminum heaters is quite affordable, especially when you consider that they will save you enough heat and reduce the consumption of gas or solid fuel to a minimum.

When planning the purchase of heating radiators, do not focus on the appearance of the product and its cost. First of all, it is necessary to clarify whether the working atmosphere and the presence of water hammers in your heating network allow the installation of aluminum radiators. If you live in a private house, there are no restrictions, but for high-rise buildings it is advisable to choose a bimetallic option. The number of sections in the battery is calculated based on its thermal output and the volume of the room.

When calculating, it is better to resort to the help of specialists. Pay particular attention to the labeling. If large Italian manufacturers of bimetallic and aluminum radiators strictly control the quality of their products, assembled in Russia or China from original components, then many one-day Chinese firms stamp dubious products decorated with the words “Italian Design”. Do not forget to check the phone numbers of the manufacturer's official service center. Remember: the price of an Italian appliance simply cannot be low.

Features of aluminum radiators

The production of aluminum radiators can use casting technology or extrusion (extrusion). The extrusion method is used to reduce the cost of production, but its technical parameters suffer. The glue used instead of welding reduces the reliability of the device.

Solid heat sinks have greater reliabilitythan combined, due to the lack of joints using gaskets that can leak over time.

Aluminum
susceptible to corrosive processes, therefore, the inner layer of the radiator must be protected from contact with the coolant. Under normal conditions, aluminum is little affected by water; a protective oxide film forms on its surface in an air environment and in the presence of oxygen, but there, where oxygen access is limited- aluminum starts to react. Sometimes hydrogen is released during reactions with water; it can explode a radiator in the presence of a flame. To avoid this, the taps on aluminum radiators must be kept open.
This problem can be solved in two ways:

• Apply to the inner surface of radiators protective polymer layer;
• Reduce acid-base balance pH of water up to 8.

Strengths of aluminum radiators

If we compare them with the main competitors in the heating appliance market - cast iron and bimetallic radiators, the following advantages of aluminum can be noted:

• high heat transfer
• low cost
• light weight

Weak sides

Disadvantages are:

• instability to corrosive processes;
• fear high pressure, used in apartment buildings.

High heat transfer contributes to low system inertiaassembled from aluminum batteries. This means that the system will circulate a coolant with a lower temperature compared to similar systems with cast iron or bimetallic radiators, which reduces the load on the boiler and prolongs the duration of work.

Most often, aluminum radiators are installed in private houses and small cottages. However, use in city apartments is also possible, today batteries with enhanced properties are produced.

Italian made aluminum radiators

One of the most well-known manufacturers that manufacture and supply aluminum heating radiators from Italy to our country is the FONDITAL concern.The devices of this company are designed taking into account the increased aggressiveness of the coolant (both physical and electrochemical) and the hydraulic instability of domestic, especially centralized, heat supply systems.

The configuration of the inner surface of the radiator also prevents dirt deposits due to poor-quality cleaning of the circulating coolant. The coating of the outer surface of the device is made according to modern, resistant to external influences, technology - two-layer painting of sections with enamel using various methods (the first one is based on the principle of anaphoresis, the second one is spraying).

The most common representatives of FONDITAL heating devices are Calidor S3 radiators, Garda and Solar devices.

The younger, but no less reliable, "brothers" of FONDITAL radiators are the Nova Florida heaters. Its ExtraTherm radiators are characterized by increased durability (designed for operating pressures up to 0.16 MPa) due to the cast production and the use of the "injection molding" method.

In addition, the ExtraTherm production line is represented by various modifications of devices (MAIOR, Serir - 6 atm, ASTOR, GENIALE, etc. - 16 atm), which are aimed at taking into account all kinds of technical nuances of heating.

The competition for these manufacturers is the relatively young company Radiatori (Italy, Bergamo). For ten years in the market of heating equipment, Radiatori has seriously declared the reliability of its HELYOS radiators. Their hydraulics and aerodynamics provide almost 100% heat transfer efficiency and improved space heating.

Carrying out a large complex of tests of its products allowed the company to offer a serious guarantee for its devices - up to 10 years (with an estimated service life of 50 years).

Heating systems from Italy, like no others, are adapted to the European market. A separate discussion is demanded by such a joint product of our domestic and Italian developers as bimetallic radiators Rifar.

Aluminum Italian radiators for heating, judging by their appearance, you can not only heat the house, but also decorate its interior

According to the main parameters, Italian radiators for the Russian market, according to experts, are maximally optimized for both autonomous and centralized heating systems in our country. They take into account not only external characteristics such as design, but also more serious ones: here and the unstable quality of the coolant; and probable pressure drops, even water hammer (in the case of outdated boiler equipment); and types of common heating systems in the regions and much more. The devices initially (at the design stage) take into account the potential increased aggressiveness of heat carriers (physical and electrochemical), hydraulic instability of Russian heat supply systems.

Bimetallic Italian heating radiators

Heating equipment manufactured using bimetallic technology is gaining more and more popularity and popularity. Salons offering Italian bimetallic heating radiators note the increasing demand for this type of heating device. This is, rather, connected not with high purchasing power (and bimetallic devices are somewhat more expensive than aluminum ones), but with their longer service life and reliability.

An example of such a combination of positive qualities of radiators made separately from aluminum and steel are bimetallic devices from the Italian companies Global, Sira.

The principles of equipment production at the factories of these companies are generally similar: bimetallic radiators are made by the method of aluminum ribbing of a steel base. Such equipment has a strong steel core, but at the same time, its heat dissipation is at the level of aluminum devices.

Global Style radiators, for example, perform well in district heating systems, where hydraulic shocks and sudden pressure drops in indoor pipelines often occur. The configuration of batteries with an aluminum heating surface allows the bimetallic radiator to harmoniously fit into any interior style.

You can endlessly argue about which manufacturer is better in the production of heating radiators. But the fact that Italians are unsurpassed masters in all areas of heating technology is a statement that has been tested by time and comfort.

Radiators from Hungary

Solid cast aluminum radiators NAMI have long been known in the Russian market. Many sellers characterize these models as the best combination of quality and price. Indeed, NAMI has a series also adapted to non-standard characteristics of the coolant - it is called NAMI Grande:

• Radiator Nami Classic
  Double anti-corrosion coating;
• Heat carrier temperature up to 120 ° С;
• Acceptable pH value up to 12;
• Working pressure 12 atmospheres;
• Heat transfer section 195 W;
• Section price is less than 400 rubles;
• 10-year warranty.

There are also standard NAMI Classic radiators. They cost about the same, but do not have such high characteristics and therefore are not particularly interesting.

In general, Hungarian radiators are really good and have a very reasonable price - after all, this is not Italy. And they are produced at factories in China or in Russia.

Fondital

An Italian brand founded in 1970. The company's products are in great demand all over the world, including Russia. Fondital constantly delights users with new products and a wide range of high-quality equipment models.

Fondital radiators are manufactured using the injection molding method.

Types of aluminum radiators

Models are classified into four groups: cast, extrusion, combined and anodized.

The latter are made of aluminum high purity (98%), and the surface of the plates undergoes anodic oxidation, after which the strength, heat transfer and durability indicators of the products increase.

These models are expensive and not in demand in the market.

Cast

For the production of cast radiators used aluminum and silicon alloy - durable and resistant to oxidation - corrosion. This type of battery is manufactured using injection molding technology. This technique creates sections of dense metal, devoid of pores, which reduce heat transfer.

Combined

Combines the advantages of cast and extrusion radiators... Blocks and individual sections consist of vertical extruded elements that are assembled into cast manifolds. They have both optimal heat dissipation and budget.

Extrusion sectional

Radiators consist of sections extruded on the extruder, which are pressed, welded or bonded with composite glue to each other. Outwardly, such batteries are no different from cast ones, except for specific seams on the inner ribs.

Photo 1.The internal structure of an aluminum extrusion heat sink. The product consists of separate sections.

Extruded sections are cheaper, but have a number of disadvantages. When pushing through the steel profile in the alloy production, the ribs do not reach the smoothness of the shapes, which is traumatic, and due to the peculiarities of the connection of the elements, the radiators can leak.

Ferroli

Of the Italian manufacturing firms, the steadily developing Ferroli should also be named.

The Ferroli company is more than 65 years old, and since the beginning of its opening, it has gone from a small workshop for the manufacture of gas boilers to a huge industrial group with a reliable position in the heating technology market.

Ferroli aluminum radiators

Ferroli POL aluminum radiators have a high thermal efficiency.

Ferroli radiators are very convenient due to the following points:

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

As you can see, Italian manufacturers of radiators offer a wide range of them, are leaders in the production of aluminum and bimetallic batteries. Moreover, products of a large number of Italian manufacturers are presented on the market.

Working functions of radiators

The work of any radiator is to release heat into the room air. The heater itself heats up from the boiler, which is part of the heating system of a house or apartment, and the main task of this system is to provide warmth to housing throughout the heating season without interruption and emergency stops. Modern heating devices are composite structures of several metals, mainly aluminum and steel, they are called bimetallic. There are also radiators without the inclusion of dissimilar metals in the design, and Italian aluminum radiators are the brightest representatives of this range of devices.

If the heating system includes aluminum radiators made in Italy, then they usually have their own regulation of heating the coolant, which is carried out in automatic mode, which greatly increases the comfort of using them. In addition, for installation in multi-storey buildings, heating batteries have been developed with automatic regulation of the coolant supply, which helps to constantly control the temperature in the premises.

But, in addition to the function of distributing heat, heating radiators must be safe in operation - do not leak even at the risk of water hammer, do not have surfaces with risk zones for a person (you cannot burn yourself), have an ergonomic shape and universal design, the structure should not interfere move freely and safely through the rooms.

Multi-section bimetallic aluminum radiator

Reinforced radiators withstand operating pressures up to 16 at, while conventional devices are designed for 10 at. Bimetallic radiators can operate at a pressure of 35 at. Standard aluminum heating radiators are designed to operate at 6 at. Since the devices work with a hot coolant, they must have a margin of safety for both the case itself and the connections.

What are the best Russian-made aluminum heating radiators?

For the production of radiators, imported innovative equipment is used, which makes it possible to achieve high results and produce high-quality products.

Some Russian enterprises operate under an Italian license, so the products have decent technical characteristics. Batteries from the Russian manufacturer Rifar are capable of:

• withstand a pressure of 20 atmospheres,
• they use not only water, but also antifreeze,
• provide heat dissipation of 183 watts,
• operated for up to 25 years.

If you are interested in Thermal aluminum batteries, then this option also has a pressure of up to 20 atmospheres, a protective coating, and at the same time it has a lower cost than the previous series of Russian production.

Advantages of aluminum radiators

Aluminum for the manufacture of heating devices is used due to its low specific weight, which allows radiators to be mounted on almost any surface of the premises. The light weight of the devices means simple and quick installation, savings on delivery and ease of repair. In addition, the thermal conductivity of aluminum is 3 times higher than that of cast iron. Also:

1. Due to the improved design, aluminum radiators have a large convection area that can be adjusted;
2. The inertia of such a heater is low, so the rooms warm up quickly, allowing you to save on energy resources;
3. In addition, the low inertia makes it possible to regulate the temperature much faster with the built-in thermostat quickly;
4. Due to the thinner walls of the device, more coolant is placed in its section, therefore, both heating and cooling of radiators are faster;
5. The cost that Italian manufacturers set for Russian consumers is quite competitive with domestic models;
6. Aluminum does not require additional painting, as the radiator body is covered with powder enamel, which does not emit toxic substances when heated.

Disadvantages of aluminum heaters

1. In centralized heating systems, the coolant may be of poor quality, therefore it is not recommended to install italy heating radiators in them due to the possibility of rapid corrosion of the body, but many companies adapt to the realities of Russian service and produce devices with surface protection from the inside - this is a fluorine-zirconium layer;
2. Pure aluminum, upon contact with air, is instantly covered with an oxide film, but it is destroyed as a result of the movement of the coolant through the sections, and because of this, hydrogen is released into the heating system, which causes corrosion of the aluminum body. Also, corrosion of aluminum can begin upon contact of aluminum and alkaline solutions in water;
3. If you need to drain the coolant during the repair or maintenance of the system, this is done only with a Mayevsky tap so that air does not get inside the radiator.

Internal surfaces ↑

The configuration of the actual internal surfaces of the radiator has already been designed in such a way as to prevent the accumulation of dirt due to a possibly poorly cleaned coolant. The finished sections are coated from the inside, as a rule, with fluorine and zirconium. Combining with aluminum, fluorine provides reliable protection against the damaging effects of both acidic and alkaline solutions. As for zirconium, it is widely used in the industry as a corrosion-resistant element, it enhances the protection of radiators from the unnecessary influence of a likely corrosive medium (coolant).
