These drum tunnels are used for washing of small parts in bulk and decolletage.
The process is carried out through a drum that rotates in a spiral, passing the parts through the different stages.
The continuous washing process is carried out by spraying and immersion of the parts.
The detergents used in the baths are water-based at a temperature of about 60°C depending on the process.
The drum tunnels can be configured with different processes: degreasing, rinsing, drying, passivation, rinsing, etc.
