immuG KÜHLWASSER Expert
The cooling water hose for hot applications
immuG KÜHLWASSER Expert was specially developed for use on blast furnaces. It is optionally electrically conductive or insulating. The hose transports cooling water from a wide temperature range and is protected from slag and metal splashes on the outside by heat protection coating.
Variants:
- In the standard version without steel spiral, the hose is ideally suited for connecting swiveling connections and is offered with FL loose flanges as standard.
- Optionally, the hose is protected by a flame retardant rubber cover.
- Thanks to an additional steel wire spiral, the immuG KÜHLWASSER Expert SD is dimensionally stable in suction applications and can be laid in a fixed position.
Hose connection
- loose flanges, fixed flanges
