Tecnoseal Fernstrum Keel Cooler Zinc Anodes

Tecnoseal Fernstrum Keel Cooler Zinc Anodes – FKC-01, FKC-02 & FKC-03

Tecnoseal Fernstrum Keel Cooler zinc anodes are rectangular sacrificial corrosion protection components designed for compatible Fernstrum marine keel cooling systems. They help protect metallic components of the keel cooler from galvanic corrosion while exposed to seawater.

The range includes three zinc anodes with different lengths and heights: FKC-01, FKC-02 and FKC-03. All models have a common width of 51 mm and feature two mounting positions with recessed openings for fastening to the appropriate keel cooler assembly.

The compact FKC-01 measures 126 × 51 × 22 mm and weighs 0.79 kg. The intermediate FKC-02 measures 180 × 51 × 26 mm and weighs 1.38 kg, while the larger FKC-03 measures 229 × 51 × 26 mm and weighs 1.95 kg.

All three versions share the same mounting-hole diameters, but the spacing between their mounting positions differs. FKC-01 and FKC-02 have an 82 mm mounting-hole spacing, whereas FKC-03 uses 102 mm.

Tecnoseal FKC-03 – Fernstrum Keel Cooler Zinc Anode 229 × 51 × 26 mm

The Tecnoseal FKC-03 is the longest version in this range. Its zinc body measures 229 mm (9.02 in) in length, 51 mm (2.01 in) in width and 26 mm (1.02 in) in height.

The FKC-03 differs from the smaller models not only in overall length but also in mounting-hole spacing, which measures 102 mm (4.02 in). Its mounting positions retain the same 14 mm through-hole diameter, 27 mm upper recess and 24 mm lower recess. The anode weighs 1.95 kg (4.30 lbs).

• Product Code: FKC-03
• Length (l): 229 mm / 9.02 in
• Width (a): 51 mm / 2.01 in
• Height (h): 26 mm / 1.02 in
• Hole Spacing (i): 102 mm / 4.02 in

Mounting Dimensions

All three Tecnoseal Fernstrum Keel Cooler anodes feature two recessed mounting positions. The through-holes measure 14 mm in diameter, with upper and lower recess diameters of 27 mm and 24 mm respectively.

The mounting-hole spacing is 82 mm for the FKC-01 and FKC-02, while the FKC-03 features a 102 mm spacing. This difference should be checked carefully when selecting a replacement anode.

The overall body dimensions also vary, particularly in length and height, so both the mounting arrangement and available installation space should be verified before ordering.

Original Part References

The Fernstrum Keel Cooler anode series is associated with the original part references 26244, 18744 and 28744. These references are shown for the product family in the Tecnoseal technical catalogue.

The catalogue does not identify which individual original reference corresponds to each FKC model. Confirm the required replacement using the original part number together with the technical dimensions.

Model Selection

Select the required zinc anode according to the original keel cooler configuration, overall body dimensions and mounting-hole spacing.

The FKC-01 and FKC-02 both use 82 mm mounting-hole spacing but differ in length, height and weight. The larger FKC-03 has a 229 mm body length and a wider 102 mm mounting-hole spacing.

All three models use the same through-hole and recess diameters. Confirm that the replacement matches the existing cooler before installation.

Supply: One zinc sacrificial anode for a compatible Fernstrum Keel Cooler.
