DI water for chromium-free pre-treatment

The pretreatment system performs cleaning, rinsing and preparation of the product surface. It is important for the product surface to be thoroughly cleaned of all dirt, oils, and contaminants before entering the application process. The purpose of the pretreatment system prior to powder coating is to ensure corrosion protection, optimal adhesion to the subsequent coatings, electrical insulation and minimize surface friction and abrasion.

The rinse water is demineralized water. In order to keep the water consumption to a minimum, the water is recirculated over ion exchange demineralizers. Here there are two units in parallel.
