Immersion System

Our immersion systems (ZT) form an ideal solution for bulk material and individual parts alike. The ZT series stands out with all-round cleaning using one or more immersion tanks.

If you require any further information, feel free to contact us.

System benefits

  • High-accuracy positioning
  • Fully functional even when individual immersion tanks are deactivated
  • Large parts can be cleaned within a very short time
  • High numbers of pieces
  • Several different immersions of the workpiece can be performed in a short time

Area of use

Complete wetting of the parts to be cleaned ideally cleans even complicated geometries and removes heavy soiling. Cleaning is possible with aqueous-based solutions with or without ultrasound. Several immersion tanks can be arranged in succession in order to keep the throughput time low.

Functional description

A loading portal moves the parts to be cleaned from the infeed belt to the sequence of immersion tanks either individually or as bulk material (in a container/basket). The immersion tanks are filled with the media required for treatment.

Potential treatment steps in the immersion process include cleaning, (deionised water) rinsing, treatment with liquids or ultrasound, spraying, high-pressure deburring, passivation, (vacuum) drying, and cooling.

The workpiece or goods carrier is placed in a collection position manually or automatically (e.g. in a linked process). A portal conveyor system takes care of loading and further transport from there. The number of containers or zones depends on the number of treatments. For small systems, manual transport between the zones may constitute a cost-effective variant.

The conveyor system places the workpiece or goods carrier in the respective tank. The goods to be washed can optionally be placed in a rotating device here for a rotary and/or swivel movement during the process. The medium in the tanks is set into motion using pressure flooding and special nozzles below the liquid level. This optimises the cleaning effect. The loading system removes the goods to be washed after the treatment period, moves them to the next station and puts them down there.

If the goods to be washed have recessed areas that fill with water, the loading system grippers can tip out the washing medium above the corresponding zone, minimising carry-over of medium. The cleaning baths are provided with surface flooding to prevent renewed soiling of the workpiece by contamination floating on the surface during removal. Immersion systems can have zones designed as spray or high-pressure stations, similar to a chamber system.

Drying and/or cooling can be placed upstream of manual or automated unloading. Selection of a suitable drying process depends on the workpiece and the required final condition. All process media used in the system are filtered and returned into the circuit. Filtration is adjusted to the cleanliness requirements.
