Critical functions of Expansion tanks

• Reduce system corrosion by eliminating the exposure of system expansion water to oxygen.
• Prevent negative pressure at the highest points of the system, avoiding the intake of air into the network.
• Avoid the evaporation of the system liquid.
• Avoid cavitation inside pumps and fittings.
• Keep liquid in reserve, in order to avoid a pressure drop caused by occasional losses of volume such as deaeration at system start-up.
• Compensate for variations of volume due to temperature changes.
