What is the brewboard?
Also...I did some number crunching (reference: 1 ton = 12000BTU/h = 3.5kW) and figured that with a 1 ton AC unit refrigerant system's cooling capacity, it would take a 6 gallon batch from boiling to 45F in about 45 minutes at best. A 1 ton window AC unit is about the average size to cool a medium sized room on a really hot day.
Definitely not that fast but this is about as fast as my 50F water supply and my 25' of 3/8 tube copper immersion coil (no whirlpool). I have all the equipment laying around to do this so I'll probably try it when I get some extra time.
FYI:
If Jamil can bring his 10 gallon batches from boiling down to 45F in say 3 minutes...WOW! that is some major heat exchanging! To put this in pespective refer to the above 1 ton per 1 medium size room. Jami'ls chiller system (and the like) have a cooling capacity of around 23 tons = 81.5kW = 278,305 BTU/h. This is enough heat exchange rate capacity to cool three, 3000 sq ft homes ( ~1 ton per 400 sq ft)on a hot day...WOW!
