The JBL ProTemp Coolers are cooling blowers for fresh- and seawater tanks. The coolers of this second generation allow a reduction of the water temperature by 2 - 4 ° C with increasing of the ambient temperature. Due to the new positioning of the cooling wheel, they are even more quiet than the first generation. The JBL ProTemp Coolers are available in two versions for different tank sizes. The cooling is affected by airflow on the water surface, thus by evaporative cooling. The delivery includes the cooling blower as well as a power suply with a 150 cm power cable.


  • Cooling blower with Cross-flow fan
  • Easy installation on the edge of the tank with a pane thickness of max. 2,4 cm
  • Selectable airflow direction
  • As a complement to JBL CoolControl possible
  • For tanks with 60 - 200 l as well as 90 - 300 l available

Very noisy

JBL - ProTemp Cooler - x200
JBL - ProTemp Cooler - x200

Works, but air flow is too low and it is too noisy. Even cheap fans works more efficient and whithout such noise. Very poor quality.
