Flamco Baseflex Heating Expansion Vessel 8L 12L 18L 25L 35L — Central Heating Sealed System Size:8L controls absorbency and promotes adhesionThe Flamco Baseflex is a Contra Flex diaphragm heating expansion vessel for sealed central heating and closed circuit cooling installations available in 8L, 12L, 18L, 25L, and 35L capacities (MPNs 2530025305). As water temperature rises in a sealed system, it expands and must have somewhere to go the Baseflex temporarily absorbs this expanded volume, maintaining system pressure within safe operating limits and preventing repeated activation of the
