Description
The SolarWave expansion vessels from Global Water Solutions are the high-quality solution for solar thermal systems. They control the expansion and contraction of the heat-transfer fluid in the solar circuit of indirect heat-transfer systems. A correctly sized SolarWave vessel makes topping up the system after periods of non-use or during extreme temperature rises unnecessary, prevents the discharge of system fluid through the pressure relief valve and maintains the minimum operating pressure throughout the system. The high-temperature butyl diaphragm and the high expansion volume factor are designed for the demands of solar thermal applications. Available in vertical and inline versions.
