Cleaning systems – PWA

Cleaning system - PWA

Ultrasonic cleaning system - PWA

With this machine system KLN has created a reasonably priced solution for aqueous part cleaning. Application is possible in all ranges of industry and for all kinds of contamination. The components can be compiled for any process in a modular construction system. They can be supplemented by all systems for tank care as well by an automation of the cleaning processes.

The complete PWA series is available also in special sizes.

The PWA cleaning tanks are available for determination of residual contamination.

Lift unit

Ultrasonic tanks - Lift unit

For the tanks of the SW 60 and SW 90 series we also offer a lift unit.

The product to be cleaned is loaded automatically into the tank, agitated and after a pre-set or individually set period of time it is lifted again.


Ultrasonic tanks - Agitation

Optionally a mechanical tilting mechanism for agitation of the product in the tank can be adapted. By vertical oscillation a relative movement between product and cleaning agent can be generated. This improves the removal of contamination from the product surface and optimizes the cleaning result. On the other hand the unavoidable irregularities of the ultrasonic field are settled and the cleaning result is improved.

Pump filter aggregate and gravity separator

Pump filter aggregates remove dirt and dust particles from aqueous solutions or rinsing waters. They are used in all cleaning processes which require a high quality of media with long lifetime.

Ultrasonic tanks - Pump filter aggregate 2

Gravity separators use the physical properties of the different density of liquids for the separation of floating and dropping particles in cleaning baths.

The contamination is detached separately, that means outside the cleaning chamber. Here the separator becomes active during an agitation triggered off by a circulation pump.

The contamination is discharged in concentrated form as waste oil or sediment slurry.
