G3.1.3.11 states: “The heat rejection device shall be an axial fan cooling tower with two-speed fans, and shall meet the performance requirements of Table 6.8.1G.”
In Table 6.8.1G I see two kinds of axial fan cooling towers: open-circuit and closed circuit. Which one shall I select?
Best Regards

I don't recall. Perhaps it is in the User's Manual? I do know that the value in 6.8.1G of 38.2 gpm/hp is what we check for as reviewers.
