Informações sobre o produto

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 should 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 blower is placed onto the aquarium rim (up to max. 2.5 cm thickness) and fixed with clamp screws.

Cooling by evaporation
The JBL coolers for freshwater and marine aquariums cool by 2-4 °C with the help of fans. The fans make the warm water evaporate at the water surface and thus generate cold. Comparable to evaporation cooling of a wet body part which is exposed to the wind.

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

Dados técnicos

The JBL CoolControl does not switch off when it reaches the set temperature.

Please check whether the setting switch is set to “Auto”. The control unit does not switch when set to “Manual”.

Does my CoolControl work with every aquarium aerator/cooler?

The JBL CoolControl was designed for use with the JBL Cooler, and they work together perfectly. Due to different voltages, flawless function cannot be guaranteed for use with appliances from other manufacturers. Even the connector, which is optically identical at first glance, may be of varying thickness. As a result, a cooler from a different manufacturer may cause unwanted switching, leading to noises in the relay.
