The Water-Cooled Helical Coil is by far the most efficient coil option for the Annie. But.... setting up for the water supply can be a real headache. Not everyone has a faucet nearby, and not many are willing to go to the trouble of cobbling together their own pump and reservoir system. There's nothing wrong with the Flux-Concentrator Litz Coil, but if you really have your heart set on the helical coil, here's your answer!
The Water Recirculator/ Heat Exchanger consists of a 120mm mini-radiator, and matching 38x120mm fan. It's powered by a standard 12VDC wall adapter. (New Annies will contain the necessary 2 apm auxiliary power supply, but legacy Annies will need to use a wall adapter. The pump is 10,000 hour-rated, and so quiet you can barely hear it.
Here's the cool part: the fan is temperature controlled. at room temperature it will barely spin at all. at 45C it will be running at full-speed. The radiator has a very high capacity, so the fluid will rarely get above room tempearture + 5C. The controller is pictured above, but you'll never see it because it's internal.
The water inlet and outlet accept the same 1/4" poly tubing that comes with the Water-Cooled Helical Coil, so there is nothing else you need to go out and buy in order to get up and running.
