It is the start of the air system of every submarine. ## Recipe ![Electrolyzer recipe](https://1371052705-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FV22FKtcNjWW37kUFLLdR%2Fuploads%2Fgit-blob-a05c19eca54a302ae7d71e4c9291f37eb325ac8e%2Felectrolyzer.png?alt=media) ## How to use it 1. Pipe water into it. 2. Power it, with FE or with rotation (see below). 3. Pipe the oxygen out to an [Oxygen Diffuser](/create-deep-seas-wiki/deep-seas/air/oxygen-diffuser.md). Every tick it turns 10 mB of water into 10 mB of oxygen for 250 FE. That is 200 mB of oxygen per second, enough to keep four diffusers running. It holds 4 buckets of water and 4 buckets of oxygen. Pipes work on any face: water goes in, oxygen comes out. ### Power * **FE:** from an energy mod like Create Crafts & Additions, Create New Age or Create Power Grid. It stores 10,000 FE. * **Rotation:** right-click it to open its screen and put a Shaft in the module slot. The shaft now runs through the Electrolyzer, front to back. Spin it and it makes its own power: 4 FE per tick for each RPM, so 64 RPM runs it non-stop. The module costs 8 SU per RPM. ## Good to know * Its model is two blocks tall. You cannot place anything in the space above it. * It holds down to 350 m before it cracks. * The full oxygen chain is explained on [Oxygen](/create-deep-seas-wiki/deep-seas/mechanics/oxygen.md). ## Video {% hint style="info" %} Video coming soon. {% endhint %}
