Advanced thermoelectric aquarium chiller features automatic proportional temperature control and an intelligent variable speed fan to deliver cooling power that effectively maintains set water temperature from 45°F to 90°F.

Chill Solutions CSXC-1 Aquarium Chiller employs thermoelectric technology that directly converts electrical power into cooling power eliminating the need for noisy mechanical compressors, refrigerants, or ozone-depleting chemicals.
