Four top quality TEC1-12715 Peltier chips by Cold&Colder. The chips have double the performance of TEC1-12706's. The best way to get the most out of them is run them at lower voltages, around 3-6 volts. You can accomplish this by wiring the four chips in series (+ to - in daisy chain) to get 3 volts per chip with a 12 volts power supply, or 2 in series, 2 in parallel for 6V per chip. 6V is ideal if you want freezing output and 3V is ideal for general "air conditioning" type work where you want cooling without freezing.
Two 12V silent brushless miniature water pumps. 10 feet of premium pure silicone 1/4" x 3/8" tubing. Silicone will not age, crack, or crease, and remain soft and pliable for many years.This allows you to put together a water cooling module that can operate at u. P to 320 Watts if connecting 4 chips in parallel. Examples how to use this kit. Pull heat from one tub of water and into another, cooling one of the tubs of water to freezing or below if needed. Build your own air conditioner by simply adding a radiator to both sides of the setup. All parts are top quality.
