SOL Perpetua™ System Installation - Installation Materials

Because of the need to maintain a vacuum in the system for long periods of time, copper or stainless steel must be used throughout; plastic piping and connectors cannot be used. Preferably one metal such as copper is used throughout. Galvanic action between different metals will create non-condensing gases which will interfere with the functioning of the condenser hence increasing pressure and increasing the boiling temperature of the working fluid.
