How to cool my oxygen production area

Man, y'all are missing the point. Don't cool or insulate your oxygen modules. Instead, use them to cool your steam geysers. The area around an uninsulated electrolyzer always trends to 70° . The area around a geyser trends to 110°. If you put a gold amalgam oxygen module in the same thermal box as your geyser, the geyser steam can condense off of your oxygen module's outer wall, and the 90° water gets immediately processed, without travel leakage, deleting a maximal amount of heat. Then, later, you can run the oxygen past a couple of wheezeworts to make it livable.

If you have to cool down the oxygen after to keep your base from overheating, then it doesn't seem very helpful to heat it up first.

It is useful, because you have to deal with that heat either way. This spreads out the heat generation, meaning you need fewer *watts* of cooling to keep the air constantly in livable ranges. Without that thermal mass, you'll get temperature fluctuations, even if you technically have enough cooling.

Why though? The module itself provides a lot of thermal mass, and the heat differential is highest right out of the electrolyzer. It doesn't take much to cool the oxygen back down later.

Because if you only route the hydrogen and oxygen that does not have to be cooled through it, you don't have to worry about cooling the other part of the oxygen later. You can route those ducts through a thermal battery of any kind you like. You could also route natural gas ducts and petroleum pipes through them, depending on the stuff you use in your base. 

The other upside is that you don't have to pump oxygen that does not need to be pumped anyway.

The smart part is the decision to produce on site, because of the damn abyssalite nerf causing significant heat bleeding. As for the specifics, there is probably a better way you can bleed those 10.6c to get the water to condense. For example, pipping the hydrogen through the water pool might be enough, kinda like I am doing right now only with a wheezie

just make sure your gayser chamber is big enough to avoid it getting over pressurized during active period and you have enough water in the pool for the hydro

Welcome @code90

I havent tested this solution but looks easy to implement:
 

 

Can I get the details on this build, may try it just for something visually different from what I usually do

This what I ended up with. It still need some tweaking, any suggestions would be welcome:

Minor correction to this setup:

Turns out that stacking gas pumps resulted in 800/500 packets even though the pressure around was huge.. splinting them up and adding memory toggle got that back up to the nice round 1000 packets. Also removed unnecessary insolated pipes inside the facility and double down on the outside walls.

What exactly do you need help with? Overall its rather common build you probably seen it like this:

With added water cooling bit bellow which works just like in my build.

Lots of interesting designs here, thanks a bunch!

 

For the moment ill just move my oxygen production to the ice biome and use the 2 nullifiers i found to keep everything cool. I want to get rid of the heat above my base generated by my current oxygen production.

I have 2 cool steam geysers to the left of my base (pretty close to one another) and the main ice biome to the right of my base with 2 nullifiers. There is some piping involved but thats not a problem. 

 

After that, ill see if I can make something fancier

 

EDIT: Im also wondering now if I could also cool the water from the geysers using the 2 nullfiers (besides the oxygen that ill produce) ...

Edit: What I mean by thermal mass, is that the tiles of the oxygen module act as a sort of thermal battery. They're going to heat up to 70, no matter what. When the geyser is active, they heat up further, but slowly. Then, when the geyser is idle, they cool back down to 70 from whatever temperature they reached. This offsets the weak heat capacity of oxygen by spreading it out over time. The output oxygen will only heat up by a few degrees, and the total heat difference is easily dealt with.

It is not enough by itself:

	Amount	Specific Heat	Start Temp		End temp	Heating/Cooling
	g/s	(DTU/g)/°C	°C		°C	DTU/s
Water	1.000	4,179	110		99,0	-45.969
Pollyted Oxygen	888	1,010	70		99,0	26.010
Hydrogen	112	2,400	70		99,0	7.795
						-12.164

And this is if you're only looking to condense the steam, if your target temperature is 90°C the difference is much larger (around 60 kDTU/s) + you need to cool down the oxygen afterwards anyway, the only real gain is from heating the hydrogen.

When you take into account the variable nature of the eruptions it makes the whole thing even less productive heat-wise (you won't be heating the hydrogen reliably to the maximum temperature).  IMO much better to concentrate on other ways of condensing steam vents.

Here's my double AETN setup:

The second one is almost at the surface of my asteroid, while the first one is just above the oil biome. Here is how that looks over the complete map:

The insulated gas pipes are made out of ingeous rock, while the normal ones are made out of granite. I recommend radiant gas pipes (I did have enough refined metal at the time) instead of the granite normal ones, as they are specifically made for to interact with the environment. The insulated igneous rock gas pipes are good enough to keep the oxygen from heating up significantly (although there's a catch as stated below). Oxygen with normal travel speed will only heat up a couple of degrees, while starting easily around 10°C or lower.

Kind of a mistake I made was that I produce too much oxygen. This ended up with overpressurizing my base and clogging up the pipes, with of course the oxygen heating up despite the insulation. It's still not bad at all really, with oxygen still exiting around 20-25°C. I would recommend automating it, with pressure sensors around your base and only producing oxygen when pressure drops below something like 1000g.

What in the world?  Why are your electrolyzers flooded with water?  How can they possibly work like that?  It looks like you want the hydrogen to go out to the left, but there is water in the way so it can't.

This concept is as old as electrolyzer itself, I use it in my bases too. It sorts the gasses by the very specific placement of gas permeable tiles, mirrored design does not work.

To build it put 200Kg pWater and 200Kg Water into on single electrolyzer. Then seal it and prime by pumping away all gasses other then hydrogen and oxygen respectively. Start it and the electrolyzer never overpresurizes.

You can even store large mass of gasses this way, in my base hydrogen side has over 200Kg/tile and rising. I use it when my power consumption spikes.

That's really weird. How do you get exact amounts of liquid deposited somewhere?

Dupes carry always 200Kg bottles from pitcher pump to emptier, or you can pipe and micromanage it.

(Just noticed g - Kg typo in my previous post)

Essentially its a more fool proof version of the mechanical separation electrolizer setup. It's a little tricky to setup but more compact thus allow much more versatility in how you do things. Btw I seen a step by step guide somewhere that explains how to do the electrolizer bit so if you get stuck you can use that

just wanna know temp of the water, and any reason for using water? Im cooling oil to 10c but oxygen makes it out at 30c sometimes
