Expansion tank VAO 50 of the company Aquasystem, with a capacity of 50 liters. Any material, liquid, solid or gas, when heated expands (ie its volume increases) and when cooled it contracts. In water supply installations, the circulating water is constantly heating and cooling, and this leads to its constant expansion and contraction. When water expands automatically its volume in liters increases, and the extra liters, if not stored somewhere, will increase the pressure to high and dangerous levels. This is where the expansion tank intervenes, which is responsible for storing the extra liters created after expansion. It has a special membrane which ensures that the water is drinkable.
It is placed horizontally and requires a little more space than a vertical container.

Finally, the selection of the correct container size is a function of many factors, such as the water content of the entire installation, the system pressure, the total height of the installation, etc. In any case, before making a purchase, you should contact a qualified engineer so that you
