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.

TK2000, TK1000 and TK500 are all WiFi ready, requires the additional Teconnect module sold seperately

For Medium Sized Aquariums - 130 to 500 Gallons

Efficient Cooling Technology

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

Digital Thermostat

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

Efficient Design 

Solid and durable structure designed to guarantee near perfect protection against corrosion. Rotatable in-set water connections, rotatable exhaust conveyor, and smaller form-factor helps facilitate placement of chiller in confined spaces.


Ability of the TANK TK-2000 to pull down water temperatures in an 86°F room:

530 gallons 77°F 1.89 watts/gal. 9°F cooler 2.2
105 gallons 47°F 0.38 watts/gal. 39°F cooler 1.4
* Coefficient of Performance (COP) - a numerical value that represents cooling performance from a baseline room temperature of 86°F and a typical heat source (aka. Heating Load

Heater Kit

Heater is pre-installed and included in the price of this unit.This unit does not accept the UV Sterilizer Kit like its equivalent TR/TC predecessor.

The 440w heater kit is designed to work universally with all Teco SeaChill Aquarium Chillers. Installation is easy and takes less than 10 minutes. No tools required. Includes an installation guide. 

Optional Air Conveyor Extension Kit (Available as an add-on purchase.)

A kit of two modular extensions designed to extend the opening of the top-side rotating conveyor on TK-500, TK-1000 and TK-2000 aquarium chillers. Chillers can overheat when placed inside a cabinet or confined space, resulting in decreased performance, increased energy utilization, and permanent damage to internal components. These extensions can be used to help channel heat further away from the chiller's operating environment. Extensions can also be mounted to the sides of cabinets using the pre-marked holes as a guide.

Each extension is modular and extends the conveyor's vent in 2 inch increments (up to 4 inches per kit).

Optional Flow Indicator (Available as an add on purchase)

The TECO Flow Indicator is an important accessory for most aquarium system setups. Connect the Flow Indicator to any pipe or tubing that water flows through. The red fan in the middle will spin--a visual indication that water is presently flowing. The Flow Indicator can also be used to "join" tubes or pipes together.
