In case of TUNNEL.LINEAR washing tunnel with a conveyor belt, the components are loaded on a conveyor belt which conveys the pieces through the different stages of treatment: the development of the machine is in line. The treated parts pass in sequence through stages designed for washing, rinsing, blowing and drying. To these types of processes, special surface treatments such as phosphatizing, passivating/oiling, phospho degreasing, and alkaline pickling can be added.

These are particularly suitable for cleaning and chemical treatment of parts with simple shapes and a smooth surface without the critical cracks.

These machines are often used in the production lines of mechanical, automotive and aerospace companies for inter-process cleaning or for precision cleaning before assembling.

Due to their flexibility, tunnel equipments can be used for big and small productions.

While the plant is in operation it results clean, odorless and completely isolated by the environment.
