The AQUACOOLER V4 is a high-performance surface fan designed to effectively reduce the water temperature of large-volume aquariums through the principle of evaporative cooling.
This model can lower the temperature by up to 4 °C in aquariums with a capacity of up to 300 liters. It provides a reliable solution during periods of extreme heat, when lighting, pumps, ambient temperature, or sunlight cause an excessive rise in water temperature.
The majority of fish, invertebrates, and aquatic plants thrive optimally in a range between 24 and 26 °C. Temperatures above 30 °C or significant variations can cause stress, general weakening, and physiological disorders. The AQUACOOLER V4 helps maintain a stable and suitable temperature.
The unit is equipped with multiple fans protected by safety covers and adjustable up to 55°, allowing for precise airflow at the water surface. Its stainless aluminum design ensures perfect compatibility with both freshwater and saltwater aquariums.
The system easily attaches to aquarium glass or edges with a maximum thickness of 25 mm. A very low voltage safety transformer is provided for reliable and safe use.
