The surface treatment is carried out with our own pickling system for pickling and passivating.
The arising sewage water is treated in a sewage treatment plant, so that practically no sewage is produced.
Furthermore it is a scrubber integrated, which is developed and patented by HEGER. This scrubber protects our employees because the scrubber is used for sufficient removal of harmful substances. Concurrently a recirculating-air operation is driven, thereby a significant engery saving effect is obtained.
