This Reflex vertical expansion vessel is for potable water and comes in various sizing options. Closed hot water circuits cannot compress water, meaning that rise in volume from temperature change has to be accommodated by an appropriate expansion vessel. For cold water, the pre-charge pressure causes the bladder to collapse until the pump begins as the bladder inflates. The system temperature increases from the pressure and volume, in turn allowing expanded water to flow into the bladder to add volume and lessen pressure. After the temperature decreases, the pre-charge pressure pushes water back to the main water circuit.
