ResiTherm stands for electro thermal pre-stressing

Since 1985 we are pre-stressing thermally district heating pipe lines worldwide.

We lead a defined current through the steel pipe which heats up equally the steel of the whole pipe line ( 1.000 m trench length, DN 1.200).

RESITHERM- pre-heating machines can be connected in parallel in order to find the shortest pre-heating time for each pipe diameter and the best pre-heating method for each construction site situation.



The built-in electronic with self-control guarantees a safe pre-heating process. Special software programs allow a precise forecast of pre-heating time and length elongation.
