The D-D Ocean Breeze Cooling Fan system provides an efficient and reliable way to reduce aquarium temperature without the cost and complexity of a full chiller. By increasing evaporative cooling across the water surface, Ocean Breeze fans help to stabilise tank temperatures during hot weather and under high lighting loads.

The compact fan units mount neatly on the tank rim or brace and can be angled to direct airflow exactly where it is needed. Low-voltage operation, quiet running and a choice of 4-fan and 6-fan models make the Ocean Breeze range suitable for a wide variety of marine and reef aquariums.

For automated and precise temperature control, Ocean Breeze Cooling Fans are ideally paired with a suitable temperature controller such as the D-D Dual Temperature Controller . This allows the fans to switch on and off automatically in response to rising water temperature, helping maintain stable conditions without manual intervention.

Key Features

• Available in 4-fan and 6-fan configurations
• Helps reduce aquarium temperature by increasing surface evaporation
• Low-voltage, energy-efficient design
• Adjustable fan angle for targeted airflow
• Compact profile for easy mounting on most tank rims
• Ideal as a cost-effective alternative or supplement to a chiller

Practical reef cooling solution

Ocean Breeze Cooling Fans are particularly useful for reef tanks running high-output LED or T5 lighting, where temperature can quickly climb during warm periods. By promoting gentle, continuous airflow across the water surface, these fans support more stable tank temperatures and help protect sensitive corals and fish from temperature spikes.
