Abstract: A printing press liquid circulation system including a cooling pan having a dedicated power return drain having a power drain orifice and optional cooling capacity located on and as part of the pan. The system induces or suctions flow of liquid from the pan, having a pan supply orifice, to a reservoir through a return conduit by connecting the return conduit to a power return drain. Proper design of the power drain orifice and the pan supply orifice allows for a matched pan supply and return system for an open hydraulic circuit, free of foam and flooding with no adjustments required.
