disappearing lox

[Denisetwin]

So I did get a LOX maker built in my survival base, my idea of splitting the output of two thermoregulators and looping half back worked for the second using valves to merge that output into the input to solve my issue of one packet endlessly circling the feedback loop and eventually breaking the pipe.  The first worked fine until the system was almost full of hydrogen and then stopped looping, and the regulators themselves are working on an on / off beat.  Not what I was expecting.  On the plus side they are COLD, no overheat there and it was very fast to get to temp.  

A couple cycles after building realized two things, should have put a thermo sensor in the tank connected to the thermoregulators, and should have put a hydro sensor connected to the liquid pump.  Decided to let it run and see what happened.

Got LOX not too many cycles later, but one pipe outside tank instantly broke so I deconstructed it thinking I'd let some LOX build up, instead the pump pumps it to the bridge which no longer connects to anything and then nothing.  It's not going outside the tank, outside is surrounded by CO2 and I watched the Oxygen overlay.  After a cycle of that, a large bubble of liquid oxygen showed up in the pipe by the pump and then the pump finally stopped pumping.  So odd.   

Since I'm going to have to open it up and fix the sensors, does anyone have other suggestions for improvement?  It actually doesn't do bad on energy as each thermoregulator only runs every other beat although that was not my intent, as it would have been easier to use bypasses than the loop thing with valves that I tried.

you appear to be injecting most of your cold at the top the driving any heat in the chamber down into your lox before pulling that cold up the far wall and back out of the chamber to re-chill it, I would revise this, I make the bottom the coldest and draw it up from there in a wavy pattern and have had great success with this.

so change the piping from horizontal to vertical?  The free hydrogen is at the top of the tank, free polluted oxygen mid to bottom, the bottom polluted oxygen is always colder than the mid which never made sense to me. Or are you saying straight from top to bottom and then horizontal piping back up?

so in this case, the second one but the straight pipe either buried in a wall or in abysallite piping.  horizontal climbers pulling the cold up fr
