The rod is absolutely watertight, can be fully submersed, has an automatic dry run shut-off (Thermo Safety Control) and is suitable for fresh and salt marine water.
One of the most important innovations is the glass jacket:
- It increases the heating surface,
- condenses the heat, ensures optimum even heat emission and
- forms a heat shield (touching it doesn’t harm the livestock).
The jacket is made from special laboratory glass, which was developed for research purposes. Therefore it is free from pollutants that could be released into the water. It is resistant to chemical and biological substances. It doesn’t have any fissures and hair cracks through which conden-sation could penetrate. And even extreme fluctuations of temperature that can occur during a water change do not harm this glass
