TECO TK Aquarium Chiller with Built-In Heater
The TECO TK Series is a premium drop-in chiller with a built-in heater, giving your aquarium precise, rock-steady temperature control all year long. A single corrosion-proof titanium heat exchanger makes it completely safe for reef, marine, and freshwater systems, while the integrated heater and microprocessor thermostat let one quiet unit handle both cooling and heating. Choose the model that matches your system from the three sizes below.
Pair it with a matched circulation pump and explore the rest of our saltwater and freshwater equipment, including the IceCap titanium heater for supplemental heating.
Why the TECO TK Series
- Titanium heat exchanger: corrosion-proof and 100% safe for both saltwater and freshwater, so it never leaches metals into a reef tank.
- Cooling and heating in one: a built-in heating element and single microprocessor thermostat hold a precise set temperature, warming in winter and cooling in summer without a separate heater.
- Digital precision: clear digital display with tight temperature accuracy and simple one-knob setting.
- Quiet and efficient: anti-vibration construction and an efficient compressor keep noise and running costs low.
- Built for any system: ideal for reef tanks, planted freshwater, fish-only setups, frag systems, and ponds.

Which Size Is Right for You?
Match the chiller to your system's total water volume, and remember to account for your room temperature and livestock. If your fish room runs warm, you keep demanding SPS corals, or you run a lot of heat-producing pumps and lights, size up to the next model for headroom and quieter, more efficient cycling.
Setup Notes
- Plumbing: the chiller runs inline using a dedicated circulation pump and tubing. Match the pump's flow rate to your chosen model for proper performance.
- Placement: set it in a well-ventilated spot with clear airflow around the vents so it can exhaust heat efficiently.
- Shipping: these are large, heavy units that ship by freight. We will confirm freight cost and timing with you after your order.
