We've got a Monster DI unit at work, not sure any of the specs on it, but there are like 5 filters and each of them is like 12" diameter and 6ft long we dont have a need for it right now, so its not running yet. Also have a big evap tower out back that we just fired up last week. Took our process cooling water from about 50C to about 20C in <1hr....
