search on google: DIY aquarium chiller dehumidifier
The original site is down, but many places borrowed the info.
Thing is, you can get like a 1/3-1/4 HP chiller for only half price done this way.
I bought a 50 pint dehumidifier. a 25 pint is about 1/6 HP. You have to bend the cooling coils out. Put it in a sump, and hook the dehumidifier up to a 4 degree differential temp controller from a beer place online. Then, get another, aquarium temp controller and hook it up to a powerhead. The powerhead pumps water through a heat exchanger like titanium or stainless steel in the sump. Its bulkier than a normal chiller, but I am not willing to pay close to $1000 when the only real difference with chillers is a built in temp controller and titanium coils....thats about it. Its monopoly, thats all it is....
