80L High Temperature Expansion Vessel
Downloads:
This vessel is specifically designed for Solar Thermal Systems to provide a
buffer of un-circulated liquid. This buffer of cooler water is displaced during expansion and contraction of the fluid caused by heating and cooling of the system. Having this buffer means that it is the cooler un-circulated liquid which is in direct contact with the main expansion vessel, the lower temperature preserves the integrity of the membrane. The correct size of vessel must be considered prior to installation and installed by appropriately trained engineers.
