Frigoboat Keel Cooler No Zincs 4-1/2" Threaded Shaft for Marine Refrigeration

The Frigoboat Keel Cooler with a 4-1/2" threaded shaft provides highly efficient seawater cooling for Frigoboat marine refrigeration systems. Mounted through the hull below the waterline, the keel cooler dissipates heat directly into the surrounding seawater, eliminating the need for fans or pumps. Zinc anodes are not included with this model.

Both keel cooler models are available with or without sacrificial zincs. Zincs are installed on the keel cooler itself, flush with the surface. If the keel cooler is already connected electrically to the boat’s sacrificial zinc, then the zincs are not needed, while if the boat does not have a bonding system it would be advisable to use a keel cooler with zincs.
