This is the ideal cooling solution for small aquariums, 55 gallons or less. This quiet, reliable & efficient chiller uses advanced thermoelectric technology to directly convert electricity into cooling power.

Can be easily bulkheaded through a 1 1/4 in. hole into siphon overflows, prefilters, sumps or even directly into plastic aquariums.

Provides continuous chilling when plugged in to a power source, it does not have an on/off switch.

A separate temperature controller must be used to turn the device on or off at pre-determined temperatures.
