For Sale is a used, but great shape, Current Prime 1/4 HP Chiller with the internal UV feature. $400 takes all. You will need a temp controller and return pump.
15 watt Gamma UV. Unfortunately, I just discovered that the quartz tube that holds the UV bulb is cracked. It's $45 to replace. Price of the Chiller is now $350 since the tube will need to be replaced if the UV is used.
