Indirect Dry Cooling Tower (IDCT) systems have been used for over 50 years for various applications in the power industry. Active for more than three decades in the indirect dry cooling market, SPX has supplied the largest indirect system presently in operation in the world.
Steam flowing from the turbine is condensed by cold cooling water in either a surface condenser or in a jet condenser. The heated cooling water is then pumped to the heat exchangers arranged vertically around the perimeter of the natural-draft cooling tower.
