How to Unlock and Craft Cryogenic Coolant in PalworldCryogenic Coolant | Credits: Image via @HeRo Survival Guides/ PocketpairCryogenic Coolant becomes available on the Technology tree at level 31, where it costs 2 Technology Points to add to your crafting list. The recipe itself is simple: each Cryogenic Coolant costs 1 Aquatic Pal Fluid and 1 Ice Organ. For a passive option, capture a Kelpsea and assign it to a Ranch at your base to generate Aquatic Pal Fluid over time. Once you’re strong enough, hunting tougher Ice Pals like Penking, Frostallion, or Vanwyrm Cryst would net more Ice Organ per kill. A Wandering Merchant in the northeast desert biome also sells Ice Organ occasionally, which is worth checking if drops are running dry.
