Cast iron radiators MC 140 specifications

older generation remembers that during the period of mass housing construction in 60 - 70s of the last century in new homes throughout established exclusively cast iron radiators.And many of these batteries, already having served on on lveka , and even more, it is quite cope with their task today.Interestingly, when attempts were made to transfer the mass construction industry on steel plate or panel radiators, it was perceived by the public without much enthusiasm. Hosts new apartments, wintered with such "innovations", ruthlessly cut them and sought to establish a "good old" iron.There were times when even this caused panic buying, cast-iron battery fell in the category of scarce goods, and to find them was not so easy.

What won the iron battery as high trust?The secret lies in their inherent operational potential.Let's take a closer look at a battery, or as it is called correctly - cast iron radiator MS 140 specifications, variety, advantages and disadvantages, the basic rules of installation.In addition, try to independently calculate how many sections will require the battery to make it fully coped with the task of heating a specific room.

main advantages and disadvantages of cast iron radiators MC-140

If you go to a specialized hardware store, you can see for themselves in a very wide range of modern radiators.Buyer offers steel radiators of various modifications - from the panel to the tube, lightweight aluminum with a very high heat emission, the most technologically advanced and reliable bimetal.Almost all of them have a very original design, which is easy to fit into the interior of the living room.

Variety of modern radiators

order not to get confused when choosing radiators for your apartment or home, be sure to familiarize readers with the information contained in a special publication of our portal.

So why is a lot of consumers, who reject all new developments and continue to stop the choice on cast iron radiators?

• absolute advantage of cast iron batteries is their highest durability and reliability .Manufacturers estimate their operating resu pc etc. imerno 50 years.This - is not an exaggeration, as the practice shows that such heaters with proper care are much greater.

striking example of this - the battery-record holder, set in one of the palace complex of Tsarskoye Selo.She regularly serves more than 110 years, and has not yet gives no reason to doubt its reliability and make any substitution.But this - officially confirmed with fact, but actually, I think, in the homes of old housing can be found radiators with a solid experience.

By the way, not everyone knows that the history of cast-iron batteries, about the same, extant form, takes beginning in the middle of the XIX century , and it is in Russia.They were first cast in St. Petersburg still in 1855."Father" cast iron radiator is considered to be a Russian businessman Franz San Galli, owner of the factory and at the same time - the talented inventor in the field of water supply and heating.The first batteries were interesting name - "hot box» (heizkörper).And their casting technique, in principle, has not changed to this day - it uses gray cast iron and special-shaped earthenware flask.

To complete the historical digression, we can mention still one eloquent fact.Many there are monuments to the subjects of human life?But the cast-iron radiator has earned such an honor!In the century and a half mark the anniversary, in 2005, at Samara GRES is a monument - a bas-relief.Is this not evidence of the highest reliability cast iron radiator and its undeniable popularity?

• Unpretentiousness cast iron radiator to any heating system - one of its major advantages.And it is made up of several settings :

- Firstly, it is able to withstand very severe baric load - for them it is considered acceptable pressure threshold of 10 ÷ 12 atmospheres.

- Secondly, the temperature range of operation - up to 130 degrees, allowing their use in the central systems with high pressure and coolant temperature.

- Third, the cast-iron batteries have a wide section internal cavities and channels.This is the minimum the risk of blockages, and high resistance to frequent in the central heating systems waterhammer.

- Fourth , iron casting virtually immune to corrosion.This means that the radiators are absolutely not "picky" in relation to the quality of the coolant.It is no secret that circulates through the pipes of central heating systems, water is far from pure, and it hostile environment for many other batteries simply is contraindicated.But not for cast iron.

Summary - iron batteries are suitable for any of the central and autonomous heating systems without limitation.

• high heat capacity iron enables longer retain heat efficiently heat the room.Moreover, it is such a battery as much as possible have the ability, in addition to the convection air heating, to give more heat and infrared light, which is very substantial help of the entire heating system.Remember the "bursting fervor" iron battery - even at a distance from them there is warmth.No other radiator with them can not be compared in this respect.
• MS-140 Cast-iron batteries are folding design.This allows you to set the desired for a particular room number of sections, modify it as needed, to carry out the replacement of the emergency unit.

• Tse on to such cast iron radiators - is readily available.Often, hosts of the economy, even purchased second-hand batteries, which after washing and proper bulkheads serve still very long.

Some of dostoins tv etc. edstavlyayut a kind of "double-edged sword."For example, the wide channels - the one hand, benefit , but to fill them will require a lot more fluid.A high specific heat iron predetermines a very significant thermal inertia radiators.To bring them to working condition will require a lot more energy, ie boiler at startup will work harder, almost without pauses.However, this is offset by during work - iron batteries are longer remain hot even after switching off the heating .

After it may seem from the above that cast iron radiators is almost devoid serious shortcomings.However, it is not - there are also very significant "cons»:

• With all the positive qualities of cast iron, it is non-plastic, hard and brittle alloy. He does not like accented mechanical loads - just may crack.The lack of plasticity - is still and a high risk of damage during sudden temperature drops, the crystal lattice «does not have time" for the linear thermal expansion.For example, if heated to a high moderator battery suddenly gets cold water, the section wall can give a crack.Similarly - and at low temperatures, if the battery is frozen , then with a very high probability it will fail.

• Another important drawback - the excessive massiveness.Even one section (with a center distance of 500 mm), not filled with coolant , depending on the specific model can weigh 6 ÷ 7.5 kg.Plus, the mass of the connecting nipples and caps.As a result, the average battery, for example, only seven sections , can give a load of 50 kilograms already.And if the coolant mass add (and, in each section is - still 1.45 kg), the total weight of the hops have 60 kg.And because it is a conversation about a relatively small battery!What then to speak about the assembly of 10 or more sections.

This feature greatly complicates the installation work - alone, without an assistant, to meet them sometimes becomes a daunting task.Also needed powerful brackets or hooks.And yet one - not every wall structure is able to withstand such a load.

cast iron radiators have to come up with quite complex structures, with emphasis in the surface of the floor or even to gain a reverse side of the wall.

However, some models are cast iron radiators can be equipped with legs, stand, or be directly calculated for the installation on the floor - in this case, the legs become part of the design (for example, on the outer sections of the battery).

• Most comes from the factory radiator only has the primer layer.So, to make batteries maximum aesthetics, have to spend their own painting, but it is not simple as it may seem .

In addition, such repainting have to be carried out regularly, least every 3 - 5 years.

fair to say that some manufacturers still go towards customers and their products are available for sale after staining cycle multilayer polymer resistant paints or powder decorative coating.It is clear that such radiators are already significantly more expensive.

• disadvantage, similar to the above - often criticized for cast iron radiators unsightly, how said , «barracks" appearance.

Honestly, this question is very subjective, that is, lies in the plane of personal preference.Steel panel radiators also may not shine beauty, and who does not like too much the modern look of bimetallic battery, which can be difficult to fit in some interior styles.

In the end, no one bothers to cover radiators decorative screen (of course, so as not to impair the efficiency of the heating system).

How to close the radiator grille

Installing decorative screen, box, lattice to help cope with the problem of unaesthetic kind of radiators.How to choose a decorative radiator grille , so as not to reduce the efficiency of the heating system at home - read in a separate publication from our website.

And some manufacturers and practiced casting sections with a decorative execution - on the walls of the original radiator obtained relief pattern of "antique".

Main specifications of cast iron radiators MC-140

Now - about the specific technical characteristics of the various models cast iron radiators series MC-140

What does she abbreviation "MC» - this through , by the way, there is no consensus.There are versions of "modified standard", "Moscow Standard", "metal sectional", "installation sectional" and other options.

But "140" - it is quite certain value, specifying the depth (distance from the rear to the front side) of each section - 140 mm.Usually this is accompanied by the name and the second a numeric value.

• For example, MS-140 abbreviation - 500 says that it cast iron radiator with depth sections 140 mm and 500 mm center distance.

This - the most common series, which was used for installation in high-rise apartments with their large-scale construction.The average power of heat transfer such section is about 160 watts.

• But this series include still and radiators MS-140 - 300. As is clear from the classification of the name, they are different center distance- only 300 mm.Taki batteries were not as moves, but in some cases (such as low location sills), they were used.Of course, the heat transfer area have significantly less that is reflected in the characteristic heat capacity - only about 120 watts from one section.
• Available MS-140 - 500 and still one species.They are the two vertical channel sections are connected outside the diagonally arranged ribs .Such fins dramatically increases the active heat transfer area, and a section of the power increases to 190 watts.

However, these radiators are difficult to paint and require frequent cleanings.The area of ​​dust settling on the flat surfaces of ribs - big and strong when they dust talk about 190 watts from the section is no longer necessary to - losses could be around 30 ÷ 40 watts.

starting material for casting sections themselves, and very often - blind or through-traffic jams, is gray cast iron (according to the classification - MF -10).Couplings, nipples produce or malleable cast iron (CN - 30 - 6- F ), or steel (08 KP or 08 ps ).Carving on the sections, nipples and external to the traffic jams - G1 ¼ "Straight through tubes have, in addition, a threaded hole G ¾ or ½ inches.

tightness connecting nodes between the sections is provided by O-rings.For their production used a special heat-resistant rubber (PI or TTC), or paronite.

production of cast iron radiators is engaged in a number of enterprises in the Russian Federation and neighboring countries.They all adhere to, in principle, common technical standards, although the performance of the batteries may vary slightly.
