TMC Aquarium Cooling Fan

What It Is

The TMC Aquarium Cooling Fan range provides a simple, effective way to reduce aquarium temperatures using natural evaporative cooling. By increasing airflow across the water surface, the fans can reduce water temperature by several degrees without the cost or complexity of a traditional aquarium chiller.

Available in 1, 2, 3 and 5 fan models, the range allows you to choose the cooling capacity that best matches your aquarium. All models operate from a safe 12V power supply and are suitable for both marine and freshwater aquariums. :contentReference[oaicite:0]{index=0}

Why We Like It

For many aquariums, a cooling fan is all that's needed to maintain a safe summer temperature. They cost significantly less to buy and run than a water chiller, are simple to install and can make a noticeable difference during periods of hot weather.

The modular range also makes it easy to choose the correct model for your aquarium, from nano reefs through to larger display tanks. Adjustable mounting brackets allow the airflow to be directed across the water surface for maximum cooling efficiency.
