Part No: 201231

This Bowman heat exchanger manifold assembly is suitable for direct fitting to Perkins 4.99, Perkins 4.107 and Perkins 4.108 marine engines.

The Bowman PE180-3483 heat exchanger unit features an aluminium LM6M body with a cupro nickel tubestack and neoprene end covers fitted. This heat exchanger manifold and header tank has a 4 bolt flange on a 76mm x 62mm PCD with 3/8" UNF x 15 bolt holes. The heat exchanger has a 22mm raw water input, a 28mm raw water output and fresh water connections to suit 35mm ID hose.

Order gaskets, hoses and exhaust outlet as extras.

Bowman recommend NOT fitting zinc anodes because the tubes used in the construction of the heat exchangers are copper-nickel alloy, and as such they do not require a zinc anode. It is possible that if a zinc anode is fitted it can actually destroy the copper-oxide film built up by the tube as a natural defence, which can allow the tube material to be attacked.
