When installing immersion heaters at the tank rim, it is important that the orange electrical connection sleeve (or the BC or LC terminal boxes) is not immersed in the treatment liquid or exposed to vapors. Direct exposure to steam must be avoided by appropriate installation measures (e.g., a mounting flange or support).

Treatment liquids that can cause deposits or scaling on heated surfaces (e.g., potassium permanganate or phosphate baths) must be heated with a low surface load of the immersion tube, up to a maximum of 2 W/cm2.

Information on the resistance of different materials is provided for guidance only and only concerns aqueous solutions ranging from 0 °C to 100 °C. These indications are based on the chemical composition and properties of chemicals frequently used for surface treatment.

We disclaim all responsibility for the accuracy of the information provided, as many factors under the user’s control can significantly influence and modify the resistance of the indicated materials. We only assume a guarantee in cases where we confirm the material resistance in writing, based on your precise description of the main parameters.

This list does not claim to be exhaustive and does not cover all treatment liquids used in the surface treatment industry.
