Specialty GRIDCOOLER Keel Coolers
When faced with limited space or larger cooling requirements, a stacked GRIDCOOLER® Keel Cooler reduces the footprint of the keel cooler while providing greater heat transfer. The design is ideal for cooling larger engines, reducing the number of units required, or fitting into an existing application in the case of repowering.
The aluminum GRIDCOOLER Keel Cooler is designed specifically for unpainted aluminum hull applications in fresh or cold seawater environments. 5000 series aluminum alloy was selected based on its compatibility with unpainted aluminum hulls and saltwater corrosion resistance. The alloy compatibility between the hull and keel cooler prevents pitting and avoids potential damage from interacting metals.
An angled tube GRIDCOOLER Keel Cooler optimizes the heat transfer for side mounted zero knot or stationary applications. The design exploits the natural convection current created by the heat exchanger. The unique position and angle of the tubes are crafted to maximize the flow of raw water between the tubes. This configuration also resists the collection of silt and other debris from building up on the unit.
The angled tube GRIDCOOLER Keel Cooler’s tubes are positioned to enhance and exploit the natural convection current generated by the heat exchanger.
