The VSG range of Vessels 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.
Operating Temperature: -10 C - 110 C
