Aquarium Chiller

An aquarium chiller is a cooling device that keeps your tank’s water temperature stable. It removes excess heat, helping maintain the ideal environment for sensitive corals, fish, or lab specimens.

An aquarium chiller works like a mini refrigerator for your tank. Water circulates through the chiller, where it passes over a heat exchanger and cools down before returning to the tank, keeping your system at a constant temperature.

If your tank is exposed to high ambient temperatures or you keep species that need precise temperature control, you need an aquarium chiller. It prevents overheating, reduces stress on fish and corals, and maintains water quality.

To set up an aquarium chiller, connect it to your tank’s sump or filtration loop. Make sure the water pump matches the chiller’s recommended flow rate. Always install the unit in a well-ventilated area for best performance.

Yes, goldfish and coldwater fish thrive in cooler water. An aquarium chiller helps you maintain optimal temperatures year-round, preventing stress and disease.

Calculate your tank’s total water volume and the temperature you want to drop. For large tanks, choose chillers with higher horsepower (HP). A trusted aquarium chiller manufacturer like Lando can help you select the best model for your setup.

Yes! Aquarium chillers work for both freshwater and saltwater tanks. Just ensure the chiller’s materials are corrosion-proof and safe for your specific water type.

Aquarium chillers come in drop-in, inline, and thermoelectric models. For large tanks and commercial systems, inline chillers with titanium heat exchangers are the most reliable and efficient.

An aquarium chiller keeps water temperatures stable, reduces fish stress, improves coral health, and protects valuable stock in aquaculture and research environments.

To keep your chiller in top condition:

• Clean fan and condenser fins every month

• Flush the heat exchanger periodically to prevent buildup

• Check tubing and connections for leaks or blockages

• Listen for unusual sounds indicating mechanical wear

 Annual servicing by a professional helps maintain peak efficiency.

It depends on your species — most reef tanks stay between 24–26°C (75–79°F). Research your livestock’s needs and choose a chiller that can maintain that range reliably.

Place the unit in a cool, ventilated location, away from:

• Direct sunlight

• Enclosed cabinets without airflow

• Heat-producing devices

Allow 6–12 inches of clearance around the unit for proper air circulation.

Think of it like placing a desktop PC—you want airflow, not a heat trap.

Look at tank size, ambient room temperature, desired temperature drop, noise level, energy efficiency, and your preferred aquarium chiller manufacturer’s support and warranty.

Choose manufacturers with a proven track record, like Lando — known for custom OEM chillers trusted by reef farms, labs, and public aquariums worldwide.

Yes. Many systems use both to maintain a stable range — the chiller lowers excess heat, while the heater prevents sudden drops. This keeps your tank stable year-round.
