Different brand, but my front pan has reversible flow same side draw. I find that when the draw is at the section closest to the flue pan the draws are better and more consistent than when my draw is off the very front section farthest from the flue pan. Later designs are now able to draw back closer to the flue pan and they switch by just turning a valve or 2. I suggest you find one that does that, you will be happier. It may cost a little more but it will be money well spent. Mine reverses by turning 2 valves but the back draw is far better. I have 2 front pans, (a spare) but if I were younger I'd sell those 2 and get 2 with the better design for draw off.
Drawing off farther back in the pan is better because it is hotter and more consistent in temperature.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
