Guess you blew the doors off of your 200 gal/yr/household limit, ay?
While the FVs may be 7 BBLs, I never said I filled them to the brim!
However, it may be a good thing that my record keeping skills (in terms of volume brewed) are intentionally lacking at this point...
Did you buy the glycol power pack or make it yourself? I've only seen one guy who's made his own chilling unit out of an old AC, otherwise they cost between 2 and 10 grand.
I purchased this unit from Pro Refrigeration. You could DIY, but IME it was worth buying something that I knew wouldn't cause me headaches down the road. I think the "Cold Bot" (http://storeitcold.com/
) has been discussed on this forum before - I considered adapting this for fermentation temperature control purposes, but it didn't make as much sense as getting a small pro unit for my long term plan.
Caution: Brewing in Denver pieced together a glycol chiller out of an old 10 HL grundy, a compressor, condensor, pump and heat exchanger. I've seen it done before, but it wasn't the best solution for me. On the other hand, you can get a line chiller (Micromatic, Foxx and the like) for under $2k, but the capacity of those types of units is pretty limited.
