Hey y'all. I've been fooling around with rocket fuel production and wanted to share this build. It's a little different from common builds, and it performs just as well as the best of them. If you like a little extra whimsy in your game, this build is for you.

Overview

Gas comes in the bottom through a set of pre-chillers. Three for hydrogen (left) and two for oxygen (right). Once gas enters the chamber it is very near its (actual) condensation temperature. It contacts the chill plate at the top of the chamber and condenses inside the airflow tiles. Since liquid can't exist inside a tile the game teleports it directly up to the next available tile. Liquid hydrogen and oxygen collect above the condensation chamber and are pumped into the liquid reservoirs above.

Liquid should flow the opposite direction as the incoming gas. Coldest liquid running through the hydrogen side first (left).

Note that each side has a separate loop moving heat around the condensation chamber. Take care to use the same pattern of insulated and radiant pipes with this loop. The gas could condense outside the airflow tiles if it contacts too much chilling.

Not much to it. It's a little more lengthy than necessary so it looks nice and neat from the "outside". The extra hydro sensor in each collecting pool is purely aesthetic. Ribbon bridges keep the collecting pools cold.

If you don't pre-chill the system you'll get some gas in the collecting pool, but it will condense eventually because the pool is actively cooled.

Principles
This build uses supercoolant near absolute zero. It transfers heat via condensation plates and bridges. Using this method greatly reduces the likelihood of freezing liquid. I haven't seen it yet.
It also minimizes flaking points where liquid contacts insulated tile and flashes back to gas. Mesh tiles in the collecting pool and the teleportation mechanic nearly eliminates losing efficiency to flaking. It's virtually eliminated if you take a little time to pre-chill all the equipment as I'll describe below.
Rather than circulating liquid to keep it from breaking pipes this build stores it all inside thermally-isolated liquid reservoirs. Fuel is delivered by flicking the signal switch or by integrating it into your rocket automation. This is the only feature I haven't tested in survival. The collecting pool could easily be replaced with a traditional liquid tank.
 
Materials
Make smart thermal choices when selecting materials. Maximize thermal conductivity in the chill plates. I used these materials in my build:
  • Maffic or ceramic for insulated things
  • Steel for the doors (9), conveyor bridges (14), and radiant gas pipe on the oxygen side (2)
  • Gold for radiant liquid pipes (36), automation bridges (8), and power bridges (5)
  • Thermium for radiant gas pipes on the hydrogen side (3) and for radiant liquid pipes that run through the doors outside the condensing chamber (4).
  • Dirt for tempshift plates (5) in the pre-chiller
  • 200 kg supercoolant in each of the pre-chiller chambers
 
Startup
Before letting gas in it helps to let the system get down to temperature. Set the pump hydrosensers to off (above 2000). Put a little supercoolant in the collecting pools and run the system until all the chill plate doors open up. Mop up the coolant and reset the hydrosensors. Seal it up and turn on the feed.
 
AT/ST
The chill source is just two aquatuners under three steam turbines. The second AT runs about 5-25% of the time depending on demand.
