Cryogenic plant

The cryogenic plant is an advanced crafting building introduced in the Aquilo era of the game. It is the machine used for the coldest and most specialized late-game chemistry and electronics work, and it also has several recipes exclusive to it. Among its unique uses are producing Fluoroketone in both hot and cold forms, crafting cryogenic science packs, and assembling late-game military and power-related items such as the railgun, railgun turret, fusion power cell, fusion reactor, and fusion generator.

It is also notable as a high-performance crafting machine for several standard chemical and processing recipes. In addition to its exclusive recipes, it can perform ammoniacal solution separation, solid fuel from ammonia, ammonia rocket fuel, lithium processing, sulfur, sulfuric acid, explosives, plastic bar, battery, carbon, steam condensation, and acid neutralisation. Some of these recipes are tied to Aquilo technology, while others are unlocked elsewhere; acid neutralisation is specifically associated with Vulcanus. The machine can craft the cryogenic plant itself once the relevant research is available.

The cryogenic plant’s recipe list overlaps with both chemical plant and assembler work, but it is not a general replacement for them. Several oil-processing and fuel recipes, such as oil cracking and rocket fuel from light oil, can instead be performed in the biochamber, while some recipes like solid fuel from light oil remain restricted to the chemical plant.

A few practical points stand out:

• The cryogenic plant is the only machine listed for several key late-game recipes, including Fluoroketone production, the railgun line, and cryogenic science packs.
• It is also used for high-tier infrastructure and military production, including fusion power components and the captive biter spawner.
• For productivity-focused setups, a biochamber with maximum legendary productivity module 3s reaches +150% productivity, while a cryogenic plant with 8 legendary productivity module 3s reaches +200% productivity.
• Because many of its recipes depend on Aquilo-related technologies and materials such as Fluoroketone, ammonia, and lithium, the cryogenic plant is best understood as a specialized late-game machine rather than an early general-purpose upgrade.
