An upgrade to the passive cooler as a spacer-tech, power-free solution for keeping food cold and fresh. Or medicine, or corpses, or whatever else; I don't judge.
Called a 'chemical cooler' in game and requiring advanced fabrication as well as air conditioning and passive cooler techs, it runs on neutroamine and so solar flares won't mess things up.
