  Duramax DuraCooler Patented Streamlined Header Design

  Our streamlined header greatly enhance interior coolant and exterior seawater flow patterns while reducing system pressure drop within the keel cooler unit. We compared the heat transfer of the traditional square header design to the increased efficiency of the Duracooler streamlined header.

A series of engineered flow diverter “scoops’ are added along the width of the bottom edge of tube assembly creating a diversion of the seawater that “flushes” the stagnated areas between the tubes forcing convection between hot tubes and the lower temperature seawater.
