Precision, comfort, quality and safety "Made in Germany".

The temperature can be precisely adjusted from 20 to 32 °C. The control accuracy is ± 0.5 °C.
The heat is kept constant. A control lamp indicates the heating function.
The heater is absolutely waterproof, can be fully immersed, has a dry run protection (Thermo Safety Control) and is suitable for fresh and marine water. One of the most important innovations is the glass coating: 
    It increases the heating surface,
    compresses the heat, ensures optimum, uniform heat output and
    forms a heat shield (the aquarium inhabitants do not mind touching it).

The coating is made of special laboratory glass. This was created for research purposes. It is therefore free of pollutants that could be released into the water. Chemical and biological substances do not attack it. There are no cracks and hairline cracks through which condensation water could pass. It is impact resistant. And even extreme temperature fluctuations, such as those that may occur during water changes, do not affect this glass.
