Dry parts cleaning

Cleaning without mixing of media!


To increase the technical availability of processing machines, measuring machines, wet scrubbers or similar, flexible cleaning methods are required in complex production lines for intermediate cleaning.

For this core competency, KNOTH has been establishing its solutions on the market since 2003, and is by now regarded as market leader with almost 2,000 implemented systems, the SEMA Technology Group has taken over this KNOW-HOW under the brand name C-SYS I Cleaning Systems. Our so-called SurfaceAircleaner cleaning systems, also called “KNOTH BOX” by our customers, are regarded as affordable, low-maintenance and easy option for dry cleaning processes.

Simple surface cleaning is only a small aspect here, which is being met by the parts cleaning systems from KNOTH. With the continuous further development of our concepts, we have managed to establish dry parts cleaning from KNOTH as process-reliable cleaning process on the market.

Our Z-AIR-O systems, SurfaceAircleanerTM cleaning systems as well as PrecisionAircleanerTM cleaning systems can be equipped for precise cleaning requirements and can thus also be used as an alternative to many intermediate washers. The usual areas of application could thus be extended to include assembly processes in production, final assembly, precise cleaning requirements before measuring or labelling processes or similar.

C-SYS I Cleaning Systems for dry parts cleaning are tailored for every customer. Depending on cycle time, type of contamination and purity requirements, every cleaning system is optimally tailored to and configured for the respective customer specifications. Short cycle times are possible with multi-chamber systems, whereby the degree of purity – also for precise cleaning tasks – is not reduced.

C-SYS I Cleaning Systems systems are stand-alone!

Each cleaning system for dry parts cleaning from C-SYS I Cleaning Systems is available with self propelled air or their own vacuum generators. We also offer control systems for our cleaning systems. Of course it is also possible to design and build these in compliance with the respectively valid customer specifications.

The benefit for our customers: Economical and measurable generation of compressed air or of a vacuum, predictable as well as low repair and maintenance costs, independent cleaning systems and complete delivery including assembly and commissioning at customer’s premises by experienced C-SYS I Cleaning Systems employees optimally trained with these systems.

C-SYS I Cleaning Systems are flexible!

C-SYS I Cleaning Systems has various procedures included in its portfolio for dry parts cleaning:

Our Z-AIR-O systems provide the most reasonable and simplest surface cleaning (e.g. for minimising carry-over). These systems without compressed air clean the workpiece surfaces by means of a vacuum. Suction systems with connection values from 4 kW are used for this purpose. Usual purity requirements of for example 30 minutes drip-free are achievable (see oil, crankshafts, 30 sec. total cycle). Surface cleaning could hardly be more energy-saving.

If additional cleaning of holes (e.g. front edge cleaning) is required, our SurfaceAircleaner cleaning systems come into their own, which clean these areas with compressed air-saving nozzles.

Even shorter cycle times and purity requirements (e.g. dry, after oil machining incl. oil duct cleaning, see crankshaft) can be realised with our PrecisionAircleaner cleaning systems.

In general, C-SYS I Cleaning Systems does not supply products, but solutions, which are perfectly adapted to the high customer demands.

C-SYS I Cleaning Systems are energy efficient!

When designing our systems, not simply “all” areas are considered. The main focus is always on the process-oriented cleaning of specific workpiece areas, to be able to safely ensure further machining in a process-reliable way. For so-called “general cleaning” of all surfaces of a workpiece, every cleaning unit is designed so that it corresponds to the respective workpiece and cleaning is possible with minimum energy input. Each workpiece has different contours - for this reason, an energy absorbing, universal standard solution is not part of our guiding principle.
