ECO Coolers -Tehnical Functions Once again, Deltec have shown the way to reducing water temperature economically in the modern salt and fresh water aquarium. The need of water movement and light to keep salt water invertebrates and fish requires pumps and lights creating heat in the water column which is not healthy for a stable aquarium environment and leads to coral bleaching and stressed fish.

The principle of the ECO cooler borrows its technology from a water cooling tower. It is possible to use the ECO cooler in conjunction with refrigerant coolers, therefore, reducing the size of the electricity bill substantially and being secure in the knowledge that even on the very hottest days of the year the temperature in your aquarium will remain stable.
