This loop of 10 fractionators fits into the two tropics between 75-82°, and can be chained with itself. If you're encountering a problem where the blueprint collides with itself, flip it over. There is also a blueprint available for the same concept that will fit into any of the tropics between 0-75°, so look for that on here as well. Stacking the hydrogen input to 4x is highly recommended and only needs to be done once for the whole chain.
