Expansion Vessels

Rep-Diaphram-greybg

Aquaflex Expansion Vessels incorporate a diaphragm/bladder arrangement which provides a flexible barrier between the system fluid and the precharged air in the vessel. As the system water expands, the bladder also expands, pushing against the precharged air cushion. This is how the expansion is accommodated in a closed-loop system. The NR vessels are fitted with a relief valve preset to 3 Bar. The F and R series vessel’s are not fitted with relief valves. Pressure setting must be specified when ordering.
