JBL ProTemp Cooler x200 Fan Cooler

Cooling fan for aquariums from 60-200 l

3.0 (2)

JBL ProTemp Cooler x200 is a modern cross-flow fan with broad airflow -indispensable in high summer. The JBL coolers for freshwater and marine aquariums cool down by 2-4 °C with the help of cross-flow fans. Due to the air flow the warm water evaporates at the water surface and thus generates evaporative cooling.

Aquarium cooling fans move air across the water surface and support evaporative cooling during warm periods. Their effect depends on room temperature, humidity, aquarium size, surface area and the amount of air movement. Because evaporation increases, the water level and salinity in marine aquariums must be monitored and evaporation water replaced appropriately.

Compare the number and size of fans, airflow settings, noise level, power supply and mounting range. Check whether the unit fits the aquarium rim or cover and whether a temperature controller is included or available separately. A controller can switch the fan according to the measured water temperature, depending on the selected system.

Fan cooling cannot lower the water below the temperature achievable through evaporation. For applications requiring more powerful or precisely controlled cooling, compare active aquarium cooling units.
