The heat has just started buddy.
You can make on efrom a cooler..some copper tubing coiled up ..then fill the cooler with ice...use a pump to circulate the water in the tube in a cycleWill have to look into it. Not sure if they are costly. Thanks for the input.
I also have them wrapped in pillow cases, helps, but nothing mind blowing.
thats what we did for a kegger one time....you can buy a mini fridge off craigs list or classifieds....prolly cheaper to do it with a cooler...downside is refilling it with ice..but work son the same principlei've seen a thread on here where someone took apart a mini fridge and used the coolant part of the fridge to keep their res cool.. looked like it worked pretty killer.. it would take a lil work on your end, but not all that much if your somewhat handy...
you could also just purchase a chiller made for this purpose, but a nice sized one runs about five bills or better, where you could probably pick up a used mini fridge for fairly cheap, and diy one for way less money..
