Fully proliferated (except last 2 steps, PLS and ILS) ILS factory. 1.5 ILS per minute. See attached images for ease of use guide.
Note: most proliferation set for speed reduce size, change to product if you like, but output time will increase. Minor collision issues towards tropic lines, rotate refineries away from tropic lines. Can be placed in the majority of the equator band, and outer equator band so long as refineries are rotated away from poles.
