Probably, there is no such person who would dream to spend the winter in a cold apartment. Therefore, consumers are increasingly trying to choose more efficient batteries. Among them is the cast iron radiator MS-140, the technical characteristics of which will be presented below.
Why does a modern buyer choose cast-iron batteries?
Cast iron radiators have many advantages. Judging by customer reviews, people distinguish the following advantages:
- High corrosion resistance.
- Excellent thermal inertia.
- Long term of operation.
- An impressive cross-section of radiators.
- The lack of the possibility of electrochemical corrosion.
The excellent corrosion resistance of the radiators described in the article, according to users, is due to the fact that when used, the surface is covered with dry rust. It excludes the development of corrosion processes. Among other things, cast iron is durable. Therefore, garbage and stones that get inside from the heating pipes do not harm him. Buyers like the cast iron radiator MS-140, the technical characteristics of which will be presented below, also for the reason that it has good thermal inertia.
Inertia and service life
As buyers emphasize, even 60 minutes after the boiler is turned off, the batteries will retain 30% of the radiated heat. But for steel radiators, this figure is only 15%. It is impossible not to mention the long service life. If we are talking about a high-quality cast iron radiator, then such equipment can last 100 years, although manufacturers only talk about 30 years.
Due to the internal cross-section of the radiators, the described devices rarely require cleaning. Among other things, cast iron simply cannot cause electrochemical corrosion. Experienced users say: this indicates that there should simply not be any conflict with steel or plastic pipes.
Technical characteristics of the radiator MS-140
The cast iron radiator MS-140, the technical characteristics of which force consumers to choose this equipment, is manufactured in Russia and Ukraine. The maximum temperature of the coolant reaches 130 ° C, while the maximum possible working pressure is 9 bar. In one section there are two channels, which allows us to state: the design of such radiators is sectional. In one such site fits 1.35 liters of water.
How to calculate the heat transfer power? This can be done by knowing the performance of one section. So, its heat transfer is 175 watts. The section weighs 6.2 kg. This must be considered before mounting the device. The width of one section is 98 mm and the diameter of the nipple hole is 5/4 inches. As intersection gaskets of such products, heat-resistant rubber is used.
Considering the cast iron radiator MS-140, the photo of which is presented in the article, you should pay attention to the fact that the sections and plugs are made according to state standards 1412. The SCh-10 acts as a material for them. But the material for the nipples is KCH-30-6F. This part of the radiator is manufactured in accordance with GOST-1215. However, having familiarized yourself with the advantages of the devices described in the article, one should not rush to purchase them. After all, before this it is necessary to find out how many sections will be needed for the heating system to work efficiently.
additional characteristics
Cast iron heating radiators MS-140, the technical characteristics of which should be known to the consumer before buying goods, have many advantages over analog models. For example, the low chemical activity of the metal ensures a long service life in the heating networks of Russia. But low hydraulic resistance allows them to be used in systems with natural circulation.
Customer reviews suggest that the temperature of the working environment is quite high. No other similar device can withstand +130 ° C. For most, the limit is 110 ° C. Such devices have a low cost and high heat dissipation. For all other cast iron batteries, this characteristic is in the “disadvantages” section. But for the models MS-90 and MS-140, the thermal power of the sections is compared with metal and aluminum radiators.
For the MS-140, heat transfer can vary from 160 to 185 watts. The final value will depend on the manufacturer. Cast iron heating radiator MS-140 can be used even with a continuous heat transfer medium. In this case, the internal surfaces of the products will not corrode.
Reviews on the choice of a radiator taking into account sections
According to users, the number of sections will depend on the configuration of the room. The main parameter is the area. However, there are other equally important factors. Among them, buyers distinguish:
- the presence of double-glazed windows;
- zoning;
- ceiling height;
- floor;
- niche sizes;
- number of windows.
People say: if there are several windows, then radiators are recommended to be placed under each of them. This will reduce heat loss. If the cast-iron radiators MS-140 are supposed to be installed in corner rooms, it is best to choose more powerful models. They are filled with additional sections in the amount of one or two. Users claim that this requirement is due to additional heat loss, which will certainly affect human comfort.
If the ceiling height in the room does not exceed 3 m, and the area is 50 m 2 , then you should use a certain formula for calculating the number of sections. To do this, the room area must be multiplied by 100 W, and then divide the resulting value by the heat transfer of one section. If as a result you get a fractional number, then users are advised to round it up. This will provide a margin of power.
Reviews about the features of installation
Cast iron radiator MS-140, the technical characteristics of which were presented above, according to users, should be installed according to certain standards. First you need to choose the mount. They can be represented by corner or pin brackets. The latter are used to fix batteries on a wall of plaster or brick. As for the corner, they are designed for wooden walls. To fix the batteries on the corner, consumers are advised to stock up on dowels and screws.
Consumer recommendations
Cast iron radiators MS-140 500, the technical characteristics of which are presented in the article, must be installed after the correct choice of location. There must be 3 brackets or more per radiator. Using dowels and drills, the brackets are secured. At the next stage, judging by the reviews of consumers, you can proceed to fasten the radiator. Do not rush to remove the protective film from the device. Initially, you need to install it on the bracket. Otherwise, the battery may be scratched.
Conclusion
Cast iron radiator MS-140, the characteristics of which are mostly only positive, has some disadvantages. Customer reviews indicate that they should include impressive weight. The mass of the section at an intersection distance of 500 mm will vary from 6 to 7.12 kg. These will require from 6 to 14 per room. This allows you to calculate what the total mass will be. Now you can imagine that this product will have to be brought in first, and then hung on the wall. This feature can be called a disadvantage, which is expressed in complex installation.
Among the minuses, buyers also call fragility, which is not the most pleasant characteristic. With their massiveness, the described products require careful handling. After all, upon impact, they can simply burst. Fragility also indicates not the highest working pressure, which is 9 atmospheres. As for pressure testing, it varies from 15 to 16 atmospheres.
