VCC³

For Testing the Corrosion Characteristics of Materials

To prove the resistance of the technical products to corrosive gases, Vötsch developed the corrosion test chambers cabinets series VCC³. The VCC³ enables an exact dosage of the corrosive gases with a climate conditioned air volume. The main constituents of the corrosive, atmospheric trace elements are: sulphur dioxide (SO²), nitrogen oxide (NO^x), hydrogen sulphide (H²S) and chlorine gas (CL²).
