Jeds atmos guide

Im really bad at keeping this shit simple so I did it all in dot points, this guide also doesn’t tell you anything about making trit, h2 or setting up the turbine just for power generation… If there’s anything you need help with, just come find me in game, I play a shit tonne of engi and atmos at the moment and im happy to help

Basic pipe fuckery:


• T1 cans are made by using iron in your hand, clicking canister frame, adding iron to that, and using a screwdriver to finish, they explode when they have hot gasses in them, releasing all the gas inside and burning down all of atmos.
• T2 cans are made by making a t1 can and adding plasteel THEN using a screwdriver, these can withstand heat below fusion temperatures (below about 1 million K)
• T3 cans are the same as t2 cans but you add a bluespace crystal as well before finishing, these can withstand any heat (I think)

Mols pressure and temperature

• Cans contain gasses, said gasses have an amount (mols), a temperature (K) and the can itself has a pressure, which is a formula including both the temperature and volume (mols) of gas. The higher the temperature, the higher the pressure, cans also have a maximum pressure they can hold before they can’t take anymore gas. An easy way to get more mols of gas in a can is to cool it with a freezer.

Layers and layer manifolds

• Every pipe sits on a layer, to change which layer a pipe sits on, you use a layer manifold, using layers, we can stack multiple pipes travelling in the same direction on a tile without mixing the gas inside

Volume pumps vs gas pumps

• Volume and gas pumps are both straight, one way pipes (they don’t allow gas to go back through so if you have a freezer before it, the gas on the other side wont be directly cooled). Volume pumps transfer gasses by mols (I think) and gas pumps, by pressure, therefore, volume pumps will be more efficient when dealing with larger quantities of gas and gas pumps will be more efficient with lower quantities (for example, making bz).
• Injectors and vents work similar, however they are used to alter the atmosphere around them, not transfer gas between pipes

Heat transfer

• Heat transfer pipes average the temperature of the gas inside them and the gas in the atmosphere around them, they are linked to normal pipes/pumps with a junction, these are used to cool the sm by default and can also be used to make ovens or whatever… get creative!
• Also the heat transfer pipes at the bottom of the heat transfer tab are used to average the temperature of the gasses in both the pipes, letting you have a coolant loop separate to the gas you are cooling
Mixing freon 3
Gas mixers
• They mix the gas going into the two input notes, node 1 is the one directly opposite the output and node 2 is the one that isn’t node 1 (:

Gas filters

• Gas goes in, the thing you set to filter comes out the side, and the rest keeps going straight

Distro/waste loop:

• Every area should have air alarms that are used to control the operating modes, scrubbers and vents
The categories should be pretty self-explanatory, with the panic siphon just setting all the scrubbers to siphon on expanded while turning off the vents, removing all gas from a room.

• Scrubbers take specific gasses out of the air, determined by the area’s air alarm, and pipe them back to Atmos in the red pipeline. By default they should just scrub co2 so if there is a gas leak, either set the operating mode to contaminated or go into the scrubber settings and manually enable the specific gas.

• Vents fill a room with the gas in the pipes connected to them, by default they are connected to the light blue pipeline, filled with air (o2 and n2). If a room doesn’t have enough pressure/air (likely caused by a breach) you can increase the vents output pressure to fill the room, however the fastest way I find, to fill a room is by dragging an air can (white) and opening it at the default pressure to stabilise the atmos.

• The waste loop is fed by the red pipe, connecting all the scrubbers around the station. It then sorts the gasses into their respective storages using gas filters, injectors and vents. You can manually change the settings on the gas filters but the injector and vent inside the storage is controlled using the console outside.

• AIR. Air is a mix of o2 and n2 and has its own area in the storage thingos. Air is just a mix of o2 and n2 and is used to fill rooms, but not for internals. By default stations should have pipes that vent suck o2 and n2 out of their supplies and mixes them using a gas mixer, then injecting it back into the air storage.

• Freezers and heaters are machines used for, you guessed it, cooling and heating gasses. To make one, you need to make a machine frame, add the board, then 2 bins and lasers, some wire and a sheet of glass.

• When you print a “freezer/heater” board at the circuit imprinter, it has a random chance of being either a freezer or heater board, if you wanna change between the two, use a screwdriver on the board.

• When you first build a freezer or heater it should by default, be on layer 2 (in the current build, before we get another 2 pipe layers) and facing down, to change the direction of the intake, unscrew the freezer so the panel at the top is open, then wrench it to rotate it. If you want to change the layer the freezer is on, screw it open, use a crowbar to dismantle it, then use a multitool on the board and reconstruct.

Burn cans:

• A burn can is pretty much a plasma fire in a can, its typically used on heat exchanges for heating gasses to trigger reactions. If done correctly, it usually reaches temps of ~40000K with about 8000mols of gas

• To make a burn can, I like to pipe over plasma and o2 separately and mix them with a gas mixer set to 40% o2 and 60% plasma.

• After you set this up, set up a manifold after it, leading to a freezer and a connector. Turn the freezer on, wrench a t2 can and wait for the can to fill with at least 8000mols of gas.
This mix, specifically, is bad because I still had some excess gasses from earlier, but it wasn’t bad enough to ruin the result so I did it anyways. Always try to keep your mixes clean, without other gasses, especially bz in this case, as it will mix into freon, which will react with the o2, cooling the can a tiny bit and lowering the temperature.

• Once you’ve set the can up like that, change the freezer to a heater and heat it up past 375K (the picture earlier was taken after this step, before unwrenching) once the can is hot enough you can unwrench it and watch the temp rise.

IMPORTANT NOTE: gasses inside cans won’t react with each other while wrenched to a connector

Freon (basic gas mixing):

Right, so you know the basics of gas and shit, now the next step is to actually mix gasses and sell them for shitloads of money, im just gonna give you an example of an easy gas to mix but everything that doesn’t need fusion is pretty much the same.

Freon is made from Bz/Co2 and plasma (bz and co2 are 1:1 ratio, I have no idea how much plasma you need so I just fill it with as much as possible) also, the ratio is going to change to be accurate with the tg wiki in the next update.

  1. Get bz. There are 4 ways to do this, the fun way is to bumrush xenobio and steal their can as fast as possible, also on heliostation, there is a can of it that spawns in atmos roundstart. The third way is to get lucky and have it spawn on lavaland, lavaland has a random atmosphere every round, with a chance to spawn bz or miasma (which can also be straight up sold), a good way to farm this is using the aux base with a scrubber or vent setup (theres a lot of ways to do this). And finally, the fourth way is to just make it yourself (don’t ask me im clueless).

  2. Mix the bz with co2, I like to just pipe a gas mixer off the storage using a manifold and do a 50/50 ratio into a separate t2 can.

  3. Once you have the t2 can with 50/50 bz:co2, I like to just wrench it to a freezer for a bit and cool it for the next step, this is optional but if you want to get more freon the first time round its better to do this

  4. Next just fill the rest of the can with as much plasma as possible, try to get it to at least 50% plasma

  5. Now youre ready to heat up the mix on a heat transfer with a burn can
    Mixing freon 3
    This part might take a bit but its good to wait and unwrench both cans when theyre the same temperature to get the burn can burning again and the freon cooking.

  6. Once the gas in your can looks something like this,
    you can unwrench it and let the gasses react, this usually takes some time (like atleast 5 mins) so you can just leave atmos and do something else. Once all the freon has formed (either the plasma, co2, or bz has ran out) you can cool the can and separate the freon from the other gasses.

  7. Cool and separate the freon from the other gasses
    Only do this specific setup if your can has no bz leftover (or you dont want to make more freon), otherwise you can filter the freon out and pipe the rest into another t2 can, fill accordingly and re heat it for more freon.

  8. Now you should have a t1 can with 1000 - 3000 mols of freon, which can either be sold at 15cr/mol at cargo or be made into hot ice with some more advanced shit (again, don’t ask me)

TLDR: please play atmos im so lonely oh god oh fuck


ill probably update this with turbine and h2 stuff when fulp updates because I think hydrogen is changing a lot and the extra layers will probably change my turbine setup.

Mmm straimght pipfe :)

very very nice mr. jed

10/10 was able to make a freon bathroom
Perhaps you can also teach the inhabitant’s of this station how to make Hot Ice?

Oh thank god, a quick and easy atmos guide. Thank you for posting!
