While in the Cryo Chamber, the player consumes less oxygen, their suit is automatically replenished from the oxygen supplied to cryo chamber, their hydrogen supply is replenished, and their suit energy is restored.
When logged out inside a Cryo Chamber, the Engineer still consumes Oxygen, albeit slowly.
The Cryo Chamber does not restore health, so use it in tandem with a Medical Room or Survival Kit.
When there is no power on the grid it is attached to, the Cryo Chamber keeps the player alive until their oxygen supply runs out.
How to log out safely in multiplayer
The Cryo Chamber serves as a safer place to log out in multiplayer, because the player's inventory and toolbar settings are saved.
On multiplayer servers, it enables faster player load locations and provides a safer spawn point on any powered grid it is built on.
It will make the client load that very specific location first, speeding up the render distance and location of player's engineer.
If the Cryo Chamber is not owned by the occupant, the hibernating Engineer is thrown out and killed if another player chooses to enter the same Cryo Chamber.
How to tell the status
Red lights mean it's unpowered and not ready
Green lights mean it's powered and ready to be used
Cryo Chambers must be built on a powered grid to work.
On large grid, they take up 1x1x1 LG blocks and on small grid it's 3x3x4 SG blocks. The small variant was added in Version/1.191.0.
It has mount points on all sides. The large-grid Cryo Chamber has one large conveyor port on the back, and the small one has one small port on the back and two small ports on the bottom. Here you connect the Cryo Chamber to a filled oxygen supply.
This block is not airtight, but the Inset Cryo Room is an airtight block with the same functionality.
