GRIDCOOLER Stacked & Angled Tube Keel Coolers

Stacked units for more heat transfer in a smaller footprint; angled-tube units for side-mounted zero-knot or stationary duty.

Two special GRIDCOOLER layouts extend the range. The Stacked GRIDCOOLER places tube banks one above another, which cuts the hull footprint and gives more heat transfer for large cooling loads. The Angled Tube GRIDCOOLER sets its tubes at an angle to improve heat transfer in side-mounted installations where the vessel is stationary or moving at zero knots, as on dredges, barges and fixed stations.
