Avoiding air in the top of Dephlegmator

[Talix]

Hi guys

On my way to a completely modular flute. I've gotten a fair way but want to make sure that I avoid the worst pitfalls...

I'm now up to putting together my shotgun dephleg. It will consist of a 150mm section of 4" pipe, and 12 lengths of 1/2" tube. I'm aiming for about 100mm of total cooling jacket length. I'd also decided to go with baffles to improve efficiency and reactiveness. However, an issue I've suddenly become aware of is that if using cross flow (inlet at the top, outlet at bottom) the gasses suspended in the water will accumulate at the highest point of the RC, slowly leading to a decrease in efficiency toward the end of the run...

Now, I can just swap the in- and outlet, no biggie with the cross flow I've heard... But should I then also discard the baffles? It seems as if baffles are just to increase the effectiveness of cross flow heat exchange. It might even be counter productive having them if in/out are reversed.

What do you think?
