The ADAL pretreatment systems provide excellent paint adhesion, increase the quality of the finish, prevent corrosion and increase the resistance in the salt spray test.
Designed for quick installation and shorter downtime, the washers are built in a modular format and are factory tested, piped and wired.
As a system supplier and a certified specialist in accordance with the Water Resources Act - Wasserhaushaltsgesetz (WHG) - we offer cleaning and washing chambers for water cleaning agents with treatment of generated sewage in an integrated sewage treatment plant.
Washers can be built as simple single-stage modules but also as large multi-stage spraying or immersion systems, depending on the size of the part, shape, complexity, type of material and required quality of the final coating.
