TECO is not a name we hear a lot in the US but they’re making a name for themselves with some energy efficient chillers as well as their new line of dedicated fan cooling solutions.  The E-Chill line of fans comes in three sizes, 1-3 fans, and even allows you to attach low level water monitors to shut down in the case of high evaporation levels.  Much more efficient than regular chillers for small tanks, fans can easily bring the temperature of a tank down 10 degrees or more simply by “blowing off/out” the excess heat dumped into the tank via powerheards, returns and lighting.  You can situate these fans on top of the aquarium or in your sump, and they are easily attached to the edge of the tank with a hanging lip.  The lip contains the temperature probe and can also hold the water level sensor, allowing you to shut off the fans if the water level drops too low.  The E-Chill line can be controlled remotely and has three different speed settings.  They are currently available for pre-order via TECO US’s website.
