The Sampo Rosenlew tunnel cleaners of modular design are suitable for high-capacity wash applications. The tunnel type machines come are available in four different widths with spraying zones can be chosen in three standard lengths. Many different zones for drying or fresh water rinsing are available.
The Tunnel type cleaners are designed to clean components in large quantities. Parts are fed through the cleaning machine on chain or net conveyors. In the wash the parts are sprayed from above, below and the sides in the cleaning and rinsing zones. Stationary spray pipes and nozzles spray hot alkaline cleaning fluid on the parts.
In every zone there are multiple spray ramps. Depending on the needed capacity conveyor speed and length of the spraying zones are selected to achieve appropriate cleaning times. The re-circulating cleaning liquids are pumped with separate pumps from each tank to the corresponding spray zone and continuously filtrated through the filtration units.

The cleaners are already highly equipped as standard. Features such as heat and sound insulation, a stainless steel construction, automatic refill and several other kinds of equipment make the cleaner a perfectly functioning unit. Sampo Rosenlew offers accessories for the Tunnel series, which ensure easier use or prolonged wash liquid life. The cleaning process can be fully automated by integrating a conveyor system to the production line.
