Mobile Wort Chilling Station
 

I have combined my immersion pre-chiller with my counter-flow chiller.

The base is an old milk crate. Inside I have a cat litter bucket to hold ice water for pre-chilling the tap water which runs through the counter flow chiller sitting on top. I've attached wheels and a handle salvaged from an old garbage can. The handle is screwed onto an old plastic shelf board.

It may not look like much to you, but to me it's a thing of beauty! :-)

Looks pretty cool. Hauling around my CFC can get pretty unwieldy.
Do you really need to pre chill your water?

I've only used the counter-flow chiller twice. The first time without a pre-chiller my wort went into the fermentor at 75°F. The 2nd time WITH the pre-chiller, my wort came out at 70°F.

I figure I might as well use the pre-chiller, since it's simple enough to use.
