Rinsing water after quenching bath, e. g. Aquatensid BW, Aquachench

High viscose polymer (e. g. poly alkaline glycol), corrosion inhibitors (e. g. alkanolamine)

During the heating of work pieces and the connected quenching, products are often used as shock baths on the basis of high viscose polymer. These are distinguished by their very good cooling qualities, which are achieved through the formation of a reversible polymer layer on the work piece surface during the cooling. Acid must be regularly added to the quench bath, due to the deposits of the quench bath in the rinsing bath, and the rinsing bath must be treated or replaced. The treatment of the rinsing water is possible with the VACUDEST® vacuum distillation process, due to the different boiling points and it is possible to achieve a lasting high rinsing water quality. Only through VACUDEST® process with vapour compression can a germ free distillate be provided to be reused as rinsing water.

An invariably high rinsing water quality can be attained through distillation of rinsing water. The return of the distillate to the rinse and the return of the concentrate to the quench bath enables closed product circulation as well as a reduction in water consumption and in waste disposal costs.
