High temperatures can cause stress to livestock (resulting in disease outbreaks), lower oxygen levels and even bleach and kill corals.

D-D’s DC300 aquarium Chillers are compact enough to fit in most aquarium cabinets but have a cooling compacity of 300w. This makes the DC300 ideal for lowering water temperature in a 150 litre aquarium by 10°C, or a 300 litre aquarium by 5°C.



Microcomputer control - for accuracy and ease of use with a built-in temperature memory system in the case of a power failure. Integral over temperature cut off.

• Pure TITANIUM heat exchanger /evaporator - for its extreme anti corrosion properties in a saltwater environment

• Low running noise

• High efficiency, latest generation cooler - for low running costs.

• Superior quality condenser - for reliability and low noise.

• Robust metal chassis - for strength and anti-vibration properties

• Contemporary housing design - to fit with most decors.

The performance chart in the second image shows the cooling curve for the DC300 working on an aquarium of 150 litre aquarium which starts at a water temperature of 28°C. You can see the drop in temperature of the aquarium hour by hour as it is recirculated through the cooler.

The ambient air temperature in the room remains at 30°C throughout the test.

The chart shows that the temperature of the water is reduced by 10°C in a period of 12 hours.

Note that no heat from lighting or other equipment is added to the water mass during the test.

Internal fuse - T start T3.15A/250V or 5~6A/250V if T start type fuse is not available
