There doesn't seem to be much difference in cost between a Therminator and the Convoluted counterflow chillers. Is the Blichman really harder to clean? It looks like it could be sterilized by baking as easily as the the counterflow could be sanitized by pumping star-san through it. Since the Therminator has been out for awhile, has any one looked at it from a standpoint of weight gain over time? I would think that any significant build-up of garbage would be detectable, whether sterilized or not. Or maybe the capacity in ML of water or the time it takes to cool from say 200 to 100 degrees would change as crud built up inside. Anyway - I'd sure like to hear about it if a Therminator owner has torn an old one down to check it out.
