If the unit can only achieve in the teens in the freezer, that means there is not enough liquid ammonia being produced. If there is not enough liquid ammonia in the freezer section, there sure as heck will not be enough in the lower section.
OK. Reduce the volume of lower section, leaving the cooling fins of the same size, and then there will be enough coolant for the lower section, no?
In 12V compressor fridges they often put the freezer at the bottom, for easier flow of the coolant, but in ammonia machine this probably wouldn't work.
