Erm... how? Where are the "liquidator" and "universal storage unit?" I can see that the refrigerators are supposed to have converters in the VAB, but once out on the pad or in space, the inline refrigerator has no options for conversion at all, and the hex core one can only convert the resources it possesses its own liquid storage for, namely Carbon Dioxide, Carbon Monoxide, Deuterium, Hydrogen, Nitrogen, and Oxygen
EDIT: Ohh... I see. Thats extremely handy the tanks can do that. Seems like one of my mods is interfering with some things including preventing converters from working unless the converter part itself has local storage for the liquid. which is slightly odd.. I'll have to hunt that down. :[
