Hammelmann high-pressure technology
As one of the few contractors serving Silesian hard-coal mines, we use Hammelmann technology to clean vertical and horizontal pipelines without dismantling them.
The method uses high-pressure water and rotating-nozzle heads. It can also remove deposits from pipes and deep-well pumps.
The technology enables cleaning of pipelines with diameters from 50–500 mm, including compressed-air, backfilling, main dewatering, emulsion, methane-drainage, fire-protection and drinking-water systems.
