Max Gas Pressure.. what am i doing wrong


Recommended Posts

Normally the maximum pressure is 2kg / tiles and such machines stop working above that. There are ways to exceed it, but you usually don't want or need to. Dupes don't like it when the air pressure is extremely high

Oxygen diffusers are enough in the early game by the way. One is enough for 5 dupes. Electroylzers can work just like that, but they put out 70°C+ oxygen which will heat up everything over time, so they need cooling long term. You also still have oxylite, which slowly converts into gas

It does not look like the OP has found algae yet. 

@imnotfez Be careful to not spend your water too quickly, since you meed it for research, and initially also for outhouses. Try to find some algae on the map and build an oxygen diffuser. 

Also, you should make a dedicated toilet room, separate from the bedroom. Enclose each of these rooms with doors and walls to give your dupes a moral bonus (toggle the room overlay to see if you have succeeded: different rooms will be shown in different colours).

You can control in what direction dupes can pass through doors. Use that to force them to wash their hands after they have used the outhouse. Otherwise they will touch food with their pee hands and will get food poisoning (if they do, don't panic, it won't kill them).

"Insufficient oxygen generation" notification does not count oxylite off gassing so until all oxylite is gone (or other sources of oxygen not produced by a machine) it can't calculate properly how much oxygen is generated. You can have "max gas pressure" AND "Insufficient oxygen generation".

The "Insufficient oxygen generation" message is a tad misleading here.  You can't generate more oxygen because you already have 2kg/tile.  This is a problem that should fix itself as dupes consume the oxygen.  This will decrease the pressure and your oxygen production will restart.  

As others have noted, an electrolyzer is overkill for 4 dupes.  Dupes consume 100g/s and the electrolyzer running at capacity produces 888g/s of O2.  So the expected steady state here is that actually what you are seeing, and the electrolyzer will have less than 100% uptime.  I don't know if the alert is smart enough to recognize this steady state is not actually a problem.

One thing to be aware of is that there is one failure mode which you are heading towards long term, for which the alert actually makes sense.  You aren't processing the CO2 dupe output due to respiration.  This will slowly convert O2 into CO2 without lowering the pressure.  Eventually this will replace 2kg/tile of O2 with 2kg/tile of CO2, and the max gas pressure will continue to prevent the electrolyzer from working.  The behavior you are seeing could be this, and you can monitor the O2 production graphs to see if this is happening.  

However, even if it is happening this will take quite a long time to turn into a real problem because of the massive amount of O2 that you have.  There are many ways to fix it.  I find the easiest short term fix is to dig a CO2 pit down, the easiest fix medium term is to use CO2 skimmers (eventually the deepest CO2 pit will stress out the dupes and waste time as they need to climb out to breathe), and the easiest long term can be slickster farming or pumping to space.

Encase the electrolyser in an airtight box; trust me, you won't want to deal with half a base of hydrogen lying around and suffocating your dupes.

It's a good idea to have a better setup of course, but hydrogen is lighter than oxygen and it will always end up being on the very top of your base. You just need a simple pump and you'd be fine. It's practically impossible to suffocate your base because of hydrogen :)
