A wide variety of heating equipment from different manufacturers is presented to the attention of potential buyers on the market. Radiators KZTO Harmony is the embodiment of a unique engineering solution, which determines their demand. Each section is a double walled tube. The coolant moves freely along the inner cavity.
Technical characteristics of radiators Harmony
Harmony batteries are available in several varieties. All radiators belong to the equipment of a new generation, since they combine an attractive appearance and high technological characteristics. The models are equipped with columns with blind ends, their difference lies in the diameter of these columns.
The last sections can be mounted with different pitches. Columns are 25 and 40 mm in diameter. These characteristics are inherent in models with the letter designation "A".
The design features of the C-marked sections are identical to the previous models, the main difference being the design. They are equipped with hemispherical ends and tubular columns. These instruments differ in column diameters and spacing. This design decision made it possible to make Harmony radiators extremely effective.
The surface is covered with polymeric compounds of different colors. The maximum allowable pressure of heating equipment is 15 atmospheres, the pressure test reaches 25 atmospheres. The set includes thermostatic fittings. Heat transfer rates reach 4,483 watts. The manufacturer gives a 5-year warranty for its equipment.
Principle of operation
The coolant moves in the column cavity and heats the air contained inside the second pipe, which is the body. This design solution made it possible to achieve the effect of double heat transfer.
In this case, the heat inertia of the vertical segments of the system decreases, and it is not necessary to fill them with water throughout the volume. The inner and outer surface of the "shirt" heats up rather quickly, and hot air flows upward. Thanks to this, the convection effect is obtained and the heat transfer of the radiators increases.
Compared to classic models of radiators completely filled with water, the heating of Harmony radiators is faster and more efficient.
Advantages and disadvantages of radiators
Radiators Harmony, like other types of heating equipment, have advantages and disadvantages. However, the merits prevail.
- The design of the batteries is simple and at the same time it is non-separable, which guarantees high strength of the connections and no leaks.
- Heat transfer rates are significantly higher than those of analogues from other manufacturers.
- Ease of installation - due to their low weight, tubular pipes do not cause difficulties in installation. Many owners carry out all the work on their own, the main thing is to prepare a working tool in advance.
- A wide variety of design solutions - thanks to this feature, it is possible to choose the most suitable model that will advantageously fit into the design of the room.
- Resistance to high pressure indicators - there is no question of phenomenal resistance, but the vast majority of models from this manufacturer can withstand operating pressures from 12 to 15 atmospheres.
- Corrosion resistance - the greatest resistance is inherent in specially protected models, the inner surface of which is treated with a polymer coating. At this point, it is especially recommended to pay attention when buying heating items for an apartment.
Disadvantages of Harmony radiators:
- high cost, especially on a model with an unusual design;
- there is no resistance to water hammer - with a sharp and strong increase in pressure in the heating system, the steel battery may fail.
The smallest durability is typical for designer models of radiators with thin welded seams. It is recommended to use such batteries only in country houses, since there can be no water hammer in an individual heating system, the pressure is relatively low.
Review of popular models
Heating batteries from the manufacturer Harmony are produced in three modifications: A, C and R. Series A has two varieties, which differ from each other by the size of the section (25 and 40) and the diameter of the tube. The center distance can range from 15.5 to 200 mm, the maximum length is 2 m and 24 cm.
Model А40 1
It is a single-row battery, the pipe diameter of which is 4 cm, the interval between adjacent pipes is 5 cm. The product is characterized by a modern design, the inner surface of the structure is treated with an anti-corrosion coating - polymer.
Model А40 2
It is made in the form of a two-row radiator, the spacing between the tubes and the cross-sectional dimensions are 5 cm and 4 cm, respectively. The model is universal in its use - it can be installed in combination with a thermostat and in a system with a forced circulation coolant.
The maximum temperature of the working fluid should not exceed +120 degrees Celsius, the test pressure should not exceed 25 atmospheres.
Model A25 1
It is a single-row structure, the pipe diameter of which is 2.5 cm, the interval between the two sections reaches 4 cm. The battery has an attractive appearance, depending on the customer's preferences, it can be made in a radius or angular design.
Model A25 2
Has almost the same technical characteristics as the previous model. The only difference is the two-row design, due to which the heat transfer of the device is capable of reaching 5,295 W.
When buying radiators, experts recommend giving preference to tubular structures that are made of alloy steel. This material has high performance characteristics and a long service life.
Before purchasing radiators, you need to familiarize yourself with the indicators of the heating area. This will allow you to choose the most suitable model for your particular case. For example, in a living room with one or two windows, 1000 W is enough for every 10 sq.
Corner rooms tend to be colder. When carrying out standard calculations, it is recommended to add a few more sections to the resulting number. If the ceiling height is more than 3 meters, it is better to give preference to radiators, the power of which is approximately 4% higher.
