Flushing processes with hot water are used in industrial cleaning, if the desired cleaning result can no longer be achieved with alternative cleaning methods. These flushing processes are also used in industrial pre-washers before final cleaning systems or in intermediate washers, to optimise the final residual dirt values on the workpieces.
KNOTH spray cleaning systems provide precisely these properties. With a combination of flushing and hot water and subsequent dry cleaning, even oily workpieces can be cleaned to achieve results almost free from grease.
Special flushing nozzles made of particularly resistant materials guide the washing water to directly defined areas on the respective workpieces, thus ensuring a homogeneous application to all areas. This will result in especially homogeneous cleaning. Even defined pre-washing processes like for example the flushing of narrow oil ducts represent a crucial core competence for KNOTH.
Modern workpieces require precise cleaning systems. In this respect, all cleaning systems in our pre-wash and flushing systems are always precisely designed and adapted to the workpiece and the necessary cleaning requirements.
Decades of experience in dry cleaning technology and in the design of special nozzles for our blow-off boxes mean we can maximise the effectiveness of the KNOTH pre-wash and flushing systems. KNOTH spray cleaning systems with hot water can thus also be used as a replacement for industrial intermediate cleaners.
As the hardware of such pre-washing and flushing systems is notably important in the process, KNOTH pays particular attention to respective components being generally constructed outside of the process chambers. This simplifies maintenance tasks and prevents the build-up of dirt accumulations within the systems.
