Cryogenic Coolant

Tech Level 31 unlock. Craft it at the Production Assembly Line from Aquatic Pal Fluids ×1 plus Ice Organ ×1. One craft makes one Coolant. It's an early midgame intermediate, not a world pickup. If you need it, you make it.

Coolant shows up across several later paths: Electric Furnace work, the Plasma Multicutter chain, Powerful Fishing Magnet (Hexolite + Coolant + Bio Battery), Combat SMG, and related late tools. Keeping a small stockpile saves you from scrambling every time a new recipe opens.

Farm Ice Organs from Ice pals and Aquatic Pal Fluids from Water pals. Both drop from regular hunting once you know which pals you're targeting. Because Coolant is craft-only, the bottleneck is organ and fluid supply, not finding Coolant on the map.
