Frigoboat Keel Cooler With Zincs 4-1/2" Threaded Shaft for Marine Refrigeration

The Frigoboat Keel Cooler with zinc anodes included provides efficient seawater cooling while offering additional protection against galvanic corrosion. The 4-1/2" threaded shaft accommodates thicker hull installations, making it ideal for offshore sailboats, cruising yachts, and commercial marine refrigeration applications.

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.
