Gas condensation
From Unofficial Stationeers Wiki
While gas condensing into liquid is a problem that can lead to burst pipes and system failure, it can also be used to transfer energy between atmospheres.
Liquid Volatiles, Oxygen, and Nitrous Oxide are useful in Rocketry. Liquid Nitrogen is useful with Cryotubes to resurrect incapacitated players.
While there are devices like Condensation Valve , Expansion Valve, Pressurant Valve, and Purge Valve, the real workhorses are the Evaporation Chamber and Condensation Chamber built from the Kit (Phase Change Device).
