90/10 cupro-nickel tubing is resistant to waterflow erosion and serves as an antifoulant. Compact, one-piece design makes installation simple. Streamlined header design allows less pressure drop of water flowing through the cooler. External water travels more quickly to tubes increasing the heat transfer efficiency and less drag. Custom sized to your engines specifications and operational requirements.
