Equipment:

Regulation
Type: Bio degreasing plant  
Immersion plant consisting of 12 baths/chambers, bath 1 for alkaline degreasing, bath 2 for biological degreasing/rinsing and at the same time biological treatment for bath 1 (achieving an almost indefinite operation life while waste is minimal and waste water is none). The following baths/chambers are for pickling, rinsing, dripping, galvanising and cooling down. The galvanising bath is heated by gas burners, the excess heat is used via exhaust heat exchangers for heating up the other baths.
