Global bimetallic radiators: overview, characteristics, reviews

Russia is a country of central heating, with cities riddled with heating pipes. Due to the fact that the pipes are mostly underground, during repairs, abrasive impurities or even sand get into the coolant. With such water, aluminum batteries do not last long, and on the inner walls gradually begins to appear corrosion, which later leads to leaks. This was faced by the Italian manufacturer of radiators Global, when he came to our country in the 90s of the last century. To solve the problem of poor-quality coolant, the company developed bimetallic radiators, which are now known around the world.

Advantages of bimetallic radiators Global

The peculiarity of these batteries is that they are made of two layers of different metal. The inner layer is made entirely of steel, which is more resistant to harmful impurities than aluminum. However, the outer layer is still made of aluminum, which is excellent at dissipating heat. This design gives Global’s bimetallic radiators excellent performance.

• Coolant quality: >8.5 pH.
• Heat output of one section: 175 W.
• Operating pressure: 35 atmospheres.
• Pressure at pressure test: 52 atmospheres.

The design of Global bimetallic radiators largely repeats aluminum radiators. Sections are curved so that the heat is evenly distributed around the perimeter, and side lamellas provide additional heating efficiency.

In the manufacture of bimetallic devices at the factory pays special attention to each stage of production. For example, the painting of batteries takes place in several steps. First, the surface undergoes 4 stages of pre-treatment to make the paint better lay on the metal. Then the device is lowered into a bath with paint, then fired in a furnace and covered with finishing enamel. After that the device is fired again and then the second layer of paint is sprayed. In this way, the radiators retain their original appearance longer.

Comparison with Chinese radiators

Bimetallic radiators Global were the first on the market, and over time other companies began to produce similar models, but not all of them are the same in quality. For example, among Chinese radiators there are fakes. In such radiators of steel is not the entire inner casing, but only the vertical collectors (pipes), the horizontal ones are made of aluminum. With this design, the whole meaning of bimetallic radiator is lost, because the coolant with gradually destroying metal impurities passes through the aluminum collectors and negatively affects them. Especially at the junction of steel and aluminum, because in this place usually the layer of aluminum is several times thinner than in the collector itself. Such a device will fail much faster than an original full-bimetal radiator.

In addition, in Global devices vertical tubes and horizontal collector are connected by welding, which ensures 100% tightness of the connection. Other radiators may use threaded connection or adhesive, which can lead to contact between aluminum and water at the point of connection and further – to through corrosion, as in this place the aluminum layer is usually quite thin.

Reliability

Thanks to this design and the use of special alloys created specifically for the production of batteries, bimetallic radiators “Global” serve for at least 25 years. Thanks to the control at each stage of production, the share of defects at the factory is less than 0.001%. The high quality of the Italian brand products is also confirmed by international and Russian certificates.

5 pluses of Global radiators

In the rating among manufacturers of bimetallic radiators, the company’s products are in the top. What distinguishes the company’s products is the characteristics of the products. In addition to a pleasant design and high-quality painting, the technical characteristics of bimetallic radiators are very important.

1. Resistance to poor-quality heat transfer medium with a hydrogen index of 7-9,5 pH.
2. Good heat output, allowing rapid heating of the room.
3. High working pressure and immunity to hydrostatic shocks.
4. Service life of at least 25 years.
5. Competent construction with various design and size options.

According to all these indicators, we can say that the company Global produces the best bimetallic radiators for apartments or houses.

Below are the products of the company that are in the greatest demand.

Review. Global STYLE EXTRA 500 10 sections side connection RAN30I0VDKKKM1U.
Anas (25.09.2019)
Strengths: Looks stylish, not bulky, and most importantly, quality workmanship.
Disadvantages: None so far. Only installed the radiator today.
Commentary: Today is the first night I sleep without a heater. The cold was terrible. This radiator is top, heats perfectly! We will see how to continue to operate, so far pleases madly!

Review: Global Style 500 – Quality heat
Alexandr 1987 31.03.2011
FEATURES: Excellent heat output, design, quality.
Disadvantages: Not found.
For a long time I wanted to change my cast iron radiators to bimetallic. Although cast iron radiators are famous for their heat output, for some reason I did not notice it at all. And now I finally got my hands on them. Having consulted with my friend about the correct choice of radiator in relation to the area of the room and all the parts that are connected to it, we installed a six-section radiator Global Style 500. The room has become really warm, and together with it it can be added or reduced, as there are adjusting valves. In winter now absolutely no discomfort and plus it is a great design and ergonomics, which fits in the room. And I would like to add that as soon as the heating season ends, it is necessary to close the valves, as the water is drained from the risers and the radiator is subjected to corrosion. On the hall I want to install the same radiator, only already eight-section, very well as for me it has proved itself.

If the radiators of heating – Global. Already made more than one apartment with them. And at home, and at my parents, my acquaintances recommended. After all, the Italians, has long been on the market, well, and taking into account the terms of operation of this company in my environment … reliable. Universal in style. They’re super warm. What else do you need from radiators?
