Purpose, advantages and disadvantages of MC 140 radiators
The technical parameters of MC 140 cast-iron radiators allow them to be used in steam heating systems of any buildings with practically no restrictions: in private houses, country cottages, apartments in apartment buildings, administrative offices, public buildings, industrial, warehouse, retail premises. The equipment is designed for operation in temperate and cold climates (UHL).
Advantages of heating radiators MC 140
- Long service life. It is one of the most durable types of radiators with a service life of 50 years.
- Reliability. A hundred-year history of this type of radiator on the heating equipment market has confirmed in practice its high reliability.
- Anti-corrosion resistance. Cast iron does not deteriorate over time when exposed to water.
- Undemanding to the quality of the coolant. Cast iron radiators are not sensitive to the quality of the water used inside them. The presence of sand, dirt, high content of salts, acids, alkalis in water does not have a strong effect on the life of cast iron radiators.
- Simplicity of steam heating systems. Cast iron radiators can be used in networks with natural circulation of water, without using a pump. They are compatible with all types of boilers - solid fuel, gas, pellet, liquid fuel.
- Thermal inertness. Cast iron heats up for a long time, accumulates heat well, cools slowly. In a heating system, this is considered a great advantage, since after the burner is turned off, the cast-iron radiator remains warm for a long time, giving off heat to the room.
Cons of heating radiators MC 140
- Sensitivity to water hammer.
- The tendency to slagging of internal surfaces, which over time leads to a decrease in heat transfer.
- Radiators are assembled from separate sections, the joints of which are sealed with rubber gaskets. The life of the gaskets is much shorter than that of cast iron. In order to avoid leaks, after several years of operation, failed intersection gaskets must be replaced.
- The appearance of such radiators is not sophisticated enough; the surface requires painting.
Why does the modern buyer choose cast iron batteries?
Cast iron radiators have many advantages. Judging by customer reviews, people highlight the following advantages:
- High corrosion resistance.
- Excellent thermal inertia.
- Long service life.
- An impressive cross-section of radiators.
- No possibility of electrochemical corrosion.
The excellent corrosion resistance of the radiators described in this article, according to users, is due to the fact that the surface is covered with dry rust during use. It excludes the development of corrosion processes. Among other things, cast iron is durable. Therefore, it is not harmed by debris and stones that get inside from the heating pipes. Buyers like the MC-140 cast iron radiator, the technical characteristics of which will be presented below, also for the reason that it has good thermal inertia.

Advantages and disadvantages of cast iron radiators
Like all other heating devices, cast iron products have their good and bad sides. Experts attribute the following characteristics to the main advantages of such products:
- Reliability - manufacturers give a 50-year warranty for such devices.
- The products themselves, especially with proper care for them, can last much longer.
- Versatility - cast-iron radiators are allowed to be mounted in different versions of heating systems: central, autonomous.
- Low hydraulic resistance makes it possible to use them for systems with central circulation.
- Low likelihood of corrosive processes.
- Affordable price.
- Resistance to aggressive heat carrier.
- Resistance to high temperatures - they can withstand 130 degrees.
- Radiation heating - a cast-iron battery is better than a steel one, capable of heating objects located nearby.
As for the negative aspects of the product of MC models, some experts consider these to be:
- A large mass - one product with an axle distance weighs about 6-7.5 kg, while a whole battery in this case will weigh from 36 to 75 kilograms.
- The need for care - cast iron, even after priming, needs to be painted every 2-3 years.
- Mechanical shocks can crack the structure.
Some features of cast iron batteries can be both an advantage and a disadvantage of the product. Wide channels: this feature causes the need for more water, but also makes it possible to avoid clogging the system.
Technical instructions
1. The installation of heating equipment should be trusted by organizations specialized in the field of construction and installation work, which have an appropriate license.
2. Connecting radiators with less than 10 sections can be done in any way - bottom, top, diagonal. If there are more than 10 sections, then it is recommended to connect in a diagonal way: the coolant inlet is top, the outlet is bottom.
Diagonal connection of the radiator ms 140.
3. Before installing the radiator, it is necessary to carry out a hydraulic test of the integrity of the device, the tightness of the gaskets, the strength of the nipple connections. For this, hydraulic testing is carried out under a pressure of 1.5 MPa. If a leak is detected due to loosening of the nipple connections, they must be tightened and the test carried out again.
four.When changing (increasing or decreasing) the number of blocks in the radiator, it is necessary to use only gaskets that are established by the requirements of GOST 1412. After assembling the radiator, the strength of the intersection connections is checked.
This is done in a standard way - hydraulic tests are carried out under a high pressure of 1.5 MPa, exceeding the maximum permissible loads. During the test, the prefabricated structure shall not leak or allow air bubbles to pass through.
5. After the completion of the installation work, the entire water heating system is pressurized, based on the results of which an act on the commissioning of the facility is drawn up.
Installation
The number of sections has been calculated, the radiators have been purchased, it remains to be installed. There are two options here - contacting specialists, spending money, or doing everything yourself. Let's consider the second option.
Installation process
We select mounts
The first step in the installation is to select a mount for the radiator. In the photo you can see the different types of mounts.
For example, pin and corner brackets are used for sectional radiators. The first ones are used to fix the battery on a brick or plaster wall, and the corner ones are used if the wall is wooden. It should also be remembered that for corner fastening, you need to stock up on self-tapping screws and dowels.
Types of fasteners. As you may have guessed, for our case, attachments No. 3 and No. 4 are applicable
Direct installation
At this stage, you need to choose the places for installing the brackets. Remember that you need at least three brackets for one radiator. Then, using dowels and a drill, you need to fix the brackets.
The next step is to attach the radiator to the brackets.
Advice. There is no need to immediately rip off the protective film from the radiator, first install it on the brackets, and then, without fear of scratching the radiator, remove the film.
Connection examples
Carefully connect the supplied pipes to the radiator. Fasten carefully and carefully, but do not damage the threads, otherwise you will get water leak from the system. Before watching, check out the installation video in our gallery.
It is important to observe certain distances during installation. For example, the installation height above the floor should be approximately equal to 10 centimeters. The distance between the wall and the battery should be 2 to 5 cm.

Operating conditions
The radiator is used in water / steam heating systems with any kind of boiler, in which the heat carrier is ordinary water, without specific requirements for its quality.
Installation should be carried out only in a heating network that is designed, installed and operated in accordance with the regulatory documentation adopted by state industry organizations.
For Russia, such a normative act is the rules of SP 60.13330.2012 or 73.13330.2012.
Consumer Recommendations
Cast iron radiators MS-140 500, the technical characteristics of which are presented in the article, must be installed after choosing the right place. There must be 3 or more brackets per radiator. Using dowels and a drill, the brackets are fixed. At the next stage, judging by the feedback from consumers, you can start attaching the radiator. Do not rush to remove the protective film from the device. First you need to install it on the bracket. Otherwise, the battery could be scratched.
