Expansion tank Cal-Pro 105CP by Zilmet, with a capacity of 105 liters. Every material (liquid, solid, or gas) expands when heated and contracts when cooled. In heating installations, the water that circulates continuously heats and cools, leading to its continuous expansion and contraction. When the water expands, its volume in liters increases, and the extra liters, if not stored, will raise the pressure to dangerous levels.

The expansion tank is responsible for storing the extra liters created after the expansion. It is installed vertically, helping save space.

It features a base for free-standing installation without additional installation work.

The choice of the right size tank depends on factors such as the water content of the entire installation, the system pressure, the total height of the installation, etc.

Before purchasing, it is recommended to consult a specialized plumber for the best solution.
