What's Special about TECO Aquarium Chillers?
Maintaining the right temperature in your saltwater aquarium is critical for the health and stability of your reef. Temperature swings can stress corals, harm invertebrates, and even lead to fish loss. TECO aquarium chillers, especially the TK series, are trusted by reef keepers for their reliability, quiet operation, and smart design. If you're considering a chiller for your system, here's what makes TECO stand out from the rest.
Quiet and Powerful Performance
The TECO TK series delivers strong cooling power while staying surprisingly quiet. These chillers use a durable titanium heat exchanger and a high-efficiency compressor to cool your tank quickly and consistently. During operation, they produce minimal noise, making them ideal for living rooms or office setups. You can place one under your tank without it becoming an unwanted distraction.
Smart, Eco-Friendly Refrigerant
TECO chillers use R290 refrigerant, which is both energy-efficient and environmentally friendly. Compared to traditional refrigerants, R290 has an extremely low global warming potential and helps reduce energy use without sacrificing performance.
Why R290 refrigerant matters:
- Reduces energy consumption and costs up to 30% to 50%
- Replaces traditional ozone-damaging refrigerants
- Scores an impressive 3 out of 150 on the Global Warming Potential scale
Digital Controls and Built-In Safety Features
Every TECO chiller includes a user-friendly digital display that lets you set your target temperature in either Fahrenheit or Celsius. Once set, the unit maintains that temperature within a narrow range. Built-in alarms alert you to temperature fluctuations or performance issues, giving you peace of mind when you're away from the tank.
Optional TECOnnect WiFi Module for Smart Control on the Go
Want to control your TECO chiller from your phone? The optional TECOnnect WiFi Module makes it easy to monitor and adjust your chiller no matter where you are. It works with the TK-500, TK-1000, and TK-2000 models and gives you access to all the key settings through a free mobile app.
What you can do with it:
- Check your tank's temperature remotely
- Change the temperature setting from your phone
- Get alerts if something goes wrong
- Switch between Fahrenheit and Celsius
- Track how your chiller is performing over time
The module is small, easy to install, and adds a whole new level of convenience to an already great piece of equipment. Whether you're at work, on vacation, or just relaxing on the couch, you can keep an eye on your reef's temperature without needing to check the display in person.
Easy to Set Up and Maintain
One of the best things about the TK series is how simple they are to install. The inlet and outlet fittings can be rotated to fit your plumbing setup, and the compact footprint makes it easy to position the unit under or beside your aquarium stand. Maintenance is also straightforward, with a removable air filter that can be rinsed and replaced without tools.
Some Models Can Heat Your Tank Too!
One of the coolest features TECO offers is the option to both cool and heat your aquarium with the same unit. Certain TK-series models come with a built-in heater, so you don’t need a separate in-tank heater cluttering up your sump or display.
Models with built-in heating:
- TK-500H (for tanks up to 120 gallons)
- TK-1000H (for tanks up to 200 gallons)
- TK-2000H (for tanks up to 500 gallons)
These “H” models offer all the same features as the standard TK chillers, including quiet operation, energy-efficient performance, and precise digital control. It’s a simple way to manage both heating and cooling with one reliable piece of equipment.
Ready to Take Control of Your Reef's Temperature?
Whether you're battling summer heat, fine-tuning stability for your corals, or just looking to simplify your setup, TECO chillers offer a high-performance, low-maintenance solution that fits seamlessly into any serious reef system. With smart features, eco-conscious engineering, and the option for heating and remote control, it's clear why so many reefers trust TECO to keep their tanks running smoothly.
