Expansion Tanks for Radiant Heating and Plumbing

Radiant Extrol Expansion Tanks

The Amtrol is one of the main elements affecting the efficiency and reliability of the system. This designation system determines the choice of the Amtrol. As mentioned earlier, the outer Amtrol tanks for heating and water are very similar and often used by those unscrupulous vendors, peddling the buyer instead of the accumulator expansion tank for heating. And it was the correct choice of the Amtrol by 90% determines the reliability and durability of the entire system.

In the heating expansion of the liquid, and hence the loading of the Amtrol occurs slowly, and as long as the system varies slightly. However, the operating temperature can reach +90 ° C. Therefore, the primary criterion for selecting the material for Amtrol expansion tank heating system is resistant to temperature and longevity.

In systems of cold water temperature effect is not as important as the temperature of water in the system can not exceed 30 ° C. The main one is the dynamic elasticity of the Amtrol Expansion tank, because system may be included several times in an hour and quickly loading. In normal operation, its frequency response is from 5 to 15 times per hour with a well chosen volume accumulator. If the volume is chosen properly, this value can increase up to 20-30 times per hour. Of course, this operation requires a reliable, flexible Amtrol which can withstand a large number of cycles.

If the expansion tank is designed for back-up water, then neobhodimamembrana with maximum flexibility. If the tanks are designed for drinking water, the tanks used in the construction materials do not violate the chemical and organoleptic quality of water. Such tanks must be accompanied by a security certificate.

Unfortunately, there is no universal material Amtrols. If the material is elastic, it is less durable and keeps the temperature of the bad or vice versa. So, here are the main points that should be taken into account when choosing the material and type of Amtrol:

operating temperature range;
sanitary requirements (water contact with the skin when using the system);
dynamics of the system;
durability;
resistance to water diffusion

The most common failure in the expansion tank - the gap pears. What happens in case of rupture of Amtrols? Water gets into the air cavity and in contact with the walls of the tank. Of course, water is poured off, and the Amtrol changed to a new. However, as a rule, due to contact of water with the walls of the tank is a reaction of oxidation of iron, thus begins the process of corrosion that destroys the walls of the tank.

We must usually 3-4 years before the walls of the tank completely prorzhaveyut and it will become worthless. In this case usually refers to the excess of the maximum pressure during injection of air. But if the master says that all working conditions have been met, then the cause of rupture of the Amtrol to be found in another.

As already mentioned, the Amtrol accumulator may be replacement (in the form of pears) and pressed (diaphragm) that separates the Expansion tank into two parts. Most manufacturers of tanks celebrate the dignity of replacement Amtrols in the possibility of replacing them, which is significantly prolongs the life of the tank. However, as practice shows, the frequency of lesions (gaps) "Amtrol pears" markedly higher than the diaphragm. This may be due to the uneven distribution of loads due to water pressure on the area of "pears".

As a result, the maximum tension on the lower part and the "neck" pear. In the diaphragm water pressure is distributed more evenly over the surface, which ensures a uniform load, and hence the tension. In addition, because of the impossibility of replacement diaphragms, it is made of more durable material, which also reduces the likelihood of damage.

Also, many experts note that the reliability of the Amtrol tank is significantly influenced by the material of the shell. Typically, the stronger the material, so it weighs more and thus serve longer. From this we can conclude that the tanks are better, weigh more and thus more expensive. In addition, it is important to choose the correct amount of Amtrol tanks. Expansion tank for the heating system is chosen so that even at the maximum heating system pressure did not exceed the maximum allowable. Accumulator volume is calculated from the optimization of the frequency of inclusion of fuel flow.
