For people looking for a reliable, efficient, cost-effective generator solution, water-cool generators are a good choice for even a home generator. Water-cooled generators are well suited for applications where output requirements exceed the cooling capabilities of an air-cooled or hydrogen-cooled generator.
Cool, de-ionized water, supplied by a closed-loop auxiliary system, flows through copper strands in the stator winding, and the warm water is discharged at the turbine end of the generator. The output is heightened by optimization of its bar strand configuration, including hollow-to-solid-strand ratio.
Because high-output machines are so important to the overall stability of the grid, water-cooled generators need to be fairly reliable. Fan efficiency is improved to reduce loss and increase output.
