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.
Economical and Environmentally Friendly.
The ECO cooler is environmentally friendly and economical and can be used for both salt and fresh water aquariums.
The principle of the ECO cooler borrows its technology from water cooling towers used in industrial applications. Water from the aquarium is forced to evaporate which draws latent heat from the water thus cooling it down.
Eco coolers are incredibly cheap to run and are much quieter than a refrigerant cooler.
For example - to achieve 950 watts of cooling.
Refrigerant - 570 watts of electricity.
Eco- cooler - 44 watts of electricity.
It is also possible to use the ECO cooler in conjunction with a refrigerant cooler, therefore reducing the size of the electricity bill substantially and being secure in the knowledge that even on the very hottest days of summer that your system will stay cool.
*Please Note: These chillers require a separate controller; the controller displayed in the picture is not available in the United States.
Operation:
Water is gravity or pump fed to a rotating spray bar and trickles through a special open mesh then falls by gravity and is cooled as the fans switch on or off evaporating the water from the large surface area provided by the mesh. The cooled water exits the unit via a 40mm pipe positioned at the bottom of the unit and must gravity feed back into the aquarium system. The hot air that is driven off by the fans is directed away via an exhaust that is built into the cooler to one side.
