Global radiators have an interesting shape and lightweight design. These designs fit perfectly into the interior of the living space. Their manufacturer is an Italian company that offers a wide range of heating equipment. In particular, this manufacturer specializes in batteries made of various aluminum alloys.
Brief description of the manufacturer
The industrial company Global began its existence in Italy about 50 years ago. It is one of the first concerns to produce aluminum batteries. Finished products are of high quality and durability.
25 years ago, the manufacturer presented its equipment to the domestic market. Since then, heating equipment has become a leader in world rankings. Thanks to the right technology, heaters are used at home and are widely used for heating in public places.
Types of radiators Global
The declared manufacturer specializes in the production of aluminum alloy batteries, as well as bimetallic and extrusion structures. Each of the options has its own distinctive features.
Aluminum
Global Aluminum is manufactured by casting from a silicon-aluminum alloy. It works effectively in any conditions, if the optimal acidity of the coolant is observed. At the same time, it is allowed to use such radiators for country houses and the private sector, equipped with an autonomous heating system. Aluminum structures have a high degree of thermal conductivity, corrosion protection due to a special zirconium coating. They also differ in their insignificant weight.
If the inside of the radiator is not treated with the appropriate composition, due to internal corrosion, it will fail very quickly, and the tightness of the seams will be broken.
Bimetallic
Radiator Global Bimetal is a model made of an alloy of steel and aluminum. The inner part of the collector is made of steel, while on top they are covered with silumin (an alloy of silicon and aluminum). The advantages of these units include resistance to corrosive effects, as well as the ability to withstand operating temperatures up to 110 degrees. The disadvantages of Global bimetallic radiators include high cost.
Bimetallic models are suitable for heating rooms with fluctuating operating pressures. The operation of this type of equipment in apartment buildings with a low quality of the coolant is especially relevant.
Extrusion
The basis of these radiators is aluminum. Radiators are manufactured using extrusion technology. There is a cast core inside. The outer part of the structure is made by extrusion through a special machine. A special feature is a noticeable design, the height of an element can reach about 2 meters.
Extrusion models have some drawbacks. They may only be used in systems with a working pressure not exceeding 16 bar. The acidity of the coolant is normally 7-8 units.
Specifications
Since 1994, the designs of the Global brand have become popular and reliable due to the use of new technologies in the production of batteries. The heaters have the following technical characteristics:
- Maintain high working pressure (about 35 atmospheres).
- They are able to work with heat transfer fluids with pH values of 8.5 (does not apply to all models).
- Suitable for hydraulic tests, as they can withstand pressures up to 24 atmospheres.
- Separate sections have a nipple connection, there is a paranite gasket, which eliminates leakage.
- They are distinguished by increased heat transfer. For example, six sections of a radiator are enough to heat a room of 10 sq. M.
- The outer part of the battery is finished with a special white paint that is UV resistant.
The approximate life of the Global battery is 25 years. This is achieved through a special internal strengthening treatment.
Global heating radiators are easy to install and lightweight. Moreover, the number of sections can be changed at any time thanks to a special fitting.
Benefits of Global Heating Radiators
Global batteries have already been repeatedly used for arrangement in public and residential premises with a positive result. The users of the designs noted some advantages.
- Attractive design. Thanks to the original design, the heaters can be used in any rooms with an already equipped design. They fit perfectly into every interior.
- Comfort. The designs have a convenient way to control and regulate the temperature. For this, special shut-off valves are made. With their help, you can completely disconnect the battery from heating.
- Profitability. When heating is started, the batteries heat up quite quickly, providing effective heat transfer. The air in the room will be completely warmed up in 10-15 minutes.
Some design features will differ depending on the radiator model. The batteries do not lose their properties after dismantling and can be reused.
What to look for when choosing
When choosing radiators, the main emphasis should be placed on the dimensions of the window and the availability of free space under it. The battery should take up almost ¾ of the size of the window opening. In this case, the placement of the heater is carried out so that there is still 10 cm of free space under the windowsill.
The most relevant and productive models are considered:
- MIX;
- VOX;
- STYLE PLUS.
The presented designs have an aluminum and bimetallic base.
Number of sections for efficient heating
To correctly calculate the number of sections, you should know some data:
- room area;
- heat transfer indicator (available on the radiator packaging);
- constant value (100).
All data are entered into the formula N (number of sections) = 17 sq.m. (room area): 120 W (heat dissipation) * 100 = 14 sections. These calculations are mandatory, since it will be impossible to create a comfortable temperature without them.
The correct calculations and advice on choosing the design of the Global brand will help organize heating in the house without compromising the design environment. When connecting radiators with water heating, it is necessary to first clean the carrier from heavy metal connections.
