The new TANK® chiller line is the next generation of TECO's flagship SeaChill™ aquarium chillers—used by consumers and professionals for over a decade. The TECO TANK is the result of one of TECO's most ambitious and comprehensive redesigns of the SeaChill aquarium chiller to-date. New changes include an increase in cooling efficiency and improved usability, functionality, and durability.


Internationally-recognized high-end compressors and titanium coaxial heat exchangers provide high performance, low energy consumption, and low noise levels.


The TANK TK-500 comes standard with a heater built into the unit (previously, had to be purchased and installed separately). The built-in heater provides better control over water temperatures and can be operated through the digital thermostat.


Intuitive controller with accurate temperature detection from 32 to 95°F. Closed loop temperature control system with an extremely tight differential of 1°F. Displays in °F or °C, and audible alarms for certain situations.


A solid and durable structure designed to guarantee near perfect protection against corrosion. Rotatable in-set water connections and smaller form-factor help facilitate placement of chiller in confined spaces.
