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!laces traditional ozone-damaging refri sc


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