Product information

Temperature control
There are two important factors which affect the water temperature in the aquarium: firstly the room temperature and secondly direct sunlight. If the room temperature in summer increases significantly, it is important to check the temperature in the aquarium regularly. It needs to be 24-26 °C. Temperatures above 30 °C are a problem and can cause substantial damage to fish and plants. Furthermore aquariums should never be exposed to direct sunlight. The higher the temperature, the less effectively the oxygen, which is vital for the animals, dissolves.

Easy to install
The bracket of the cooling fan is placed onto the aquarium rim (up to max. 2.4 cm thickness) and fixed with clamp screws.

Cools by evaporation
The JBL xCoolers for freshwater and marine aquariums cool between 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. This is comparable to evaporation cooling a wet body part exposed to the wind.

Safety
The water cooler has a safety cover grid and is operated with an extra-low voltage of 12 V.

FAQ
How does the noise level of the new PROTEMP COOLER compare to the other coolers?

A lot of commercially available products, including our predecessor range, have two to four axial fans (depending on the model). The appearance is reminiscent of a PC fan. The design of the cross-flow fans used in the JBL PROTEMP COOLERS makes them run more smoothly and gives them a quieter air flow. Its one axis drive ensures a further reduction in noise. In models using similar technology, the bearing is typically based on sintered bushes. Thanks to a high-quality ball bearing, a dedicated bearing to give additional damping, plus a reworked bearing in the cross-flow fan wheel, the new PROTEMP COOLERS guarantee you greater stability. Rattling and squeaking are now a thing of the past.

Is rattling normal during operation?

The cross-flow fan provides an audible air flow that is uniform and must not rattle or clatter. However, if such a problem does occur, it could be an indication of damage from a fall or strong impacts on the enclosure wall. Check that the cross-flow fan is correctly mounted or if the housing is incorrectly assembled. If these are not the causes your ProTemp Cooler must be returned to the factory for inspection and repair by the JBL customer service.

Can I operate two coolers with one ProTemp CoolControl?

The ProTemp CoolControl is connected between the power supply and the ProTemp Cooler. It is therefore not possible to connect two coolers to one controller. Each Cooler needs its own controller.

The cooler does not cool down the aquarium

JBL ProTemp Coolers cool the water temperature by 2-4 °C in high ambient temperatures. To achieve this with this product, it’s important the maximum recommended aquarium volume is adhered to. Please note that the cooling effect only occurs when the cooler is in operation and that the system needs to have been running continuously for a few hours beforehand. The air flow needs to be directed across the entire width of the aquarium and be at a 45° angle to the water surface. If only a part of the water surface is ventilated or the angle is set to 90°, the desired effect will be lost or greatly reduced. The housing can be rotated 360°.

Can the CoolControl also regulate the new ProTemp Cooler x200 and x300 (generation 2)?

Yes, the CoolControl of the predecessor range can also regulate the new ProTemp Cooler x200 and x300 (generation 2) aquarium coolers.

Excellent, Worth every penny!

I have used this product within the summer and I have to say, that it managed to beat the heat! My tank's temperature was in low levels 20-23 even though the rooms temperature was 30-32! You can check a review of this product on my instagram account " nemophilist_scaper "

Ich hatte vorher andere Lüfter dran die 10x Lauter waren ich bin richtig zufrieden. Und werde jetzt ganz auf die Lüfter um stellen weil sie so Leise sind. Bin mir sicher Leiser geht schon nicht mehr und sie machen auch richtig gut Wind. JBL Beide Daumen hoch

Ventilador excepcional, he conseguido bajar la temperatura incluso 6 grados. Un aparato genial, la única pega que veo es que hace un poco de ruido, no es completamente silencioso
