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.

Teco has once again reshaped the chiller industry by introducing the most energy-efficient and environmentally friendly chiller to date for the Aquarium Tank and Hydroponic industries. Centered around a proven Hydrocarbon refrigerant compressor with R290 coolant, the new Teco CHILLER ONLY models, 500, 1000, and 2000 chillers can easily outperform traditional compressors by cutting energy consumption by 30% to 50%. Additionally, R290’s environmentally friendly characteristics mean a dramatic decrease in the earth’s ozone destruction by up to 600 times over traditional chiller coolants. 

Less operating cost and more of Earth’s ozone sound like a winning combination for everyone!


  • Reduces energy consumption by 30% to 50%
  • Replaces traditional ozone-damaging refrigerants
  • Scores 3 out of 150 on Global Warming Potential (GWP) scale


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


Intuitive controller with accurate temperature detection from 32 to 95°F. Closed loop temperature control system with an extremely tight differential of 1°C. 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.
