Sen-Dure 2666-1-5 Marine Tube & Shell Heat Exchanger / Oil Cooler-NIB

Sen‑Dure Model 2666‑1‑5 – Marine Tube & Shell Heat Exchanger / Oil Cooler
Function / Use Case:

A marine-grade shell-and-tube style heat exchanger designed to cool oil (e.g. engine lube oil, transmission oil, hydraulic oil) using an external water circuit (sea water or closed coolant loop).
Construction & Materials:
Shell: copper or copper alloy (for corrosion resistance in marine environments)
