Solvent cleaning machines
Component cleaning using solvents
From small, manually loaded compact solvent cleaning systems to fully automated large-scale cleaning systems with a throughput of several tons (per hour), we offer customized solutions for high-quality cleaning and degreasing of components using solvent cleaning systems under vacuum.
The complete process sequence of component cleaning (e.g. pre-cleaning using spraying process, flood cleaning, ultrasonic cleaning, vapor degreasing, vacuum drying) takes place in a closed working chamber. The process sequence, treatment times and all other functions of the solvent system can be preselected via the control.
The latest generation of component cleaning systems are combined systems (so-called hybrid cleaning systems) which make it possible to combine aqueous and solvent-based cleaning stages as required. This combined system allows for unprecedented flexibility in component cleaning.

Modified alcohols
Alkoxy-propanols are multifunctional compounds containing both alcohol and ether groups. They can be considered as modified alcohols derived from propanol by the addition of an ether group. Compared to the original alcohol, alkoxy-propanols have a significantly higher flash point and their cleaning effect is greatly improved. They possess good dissolving power for oils and fats, but also for polar contaminants. Specially developed formulations based on modified alcohols for various industrial cleaning applications deliver excellent cleaning results for component cleaning. Since they are pure substances or at least defined mixtures of substances with very narrow boiling ranges, alkoxy-propanols can be easily reprocessed by distillation in the solvent system, provided that the boiling point of detached contaminants does not fall within the boiling range of the alkoxy-propanols. In terms of flash point and evaporation, these are comparable to medium-boiling hydrocarbons.
Application areas:
- Polar and non-polar contaminants are dissolved
- Cleaning of different materials (e.g. metal and plastic compounds)
- Temperature-sensitive parts
- Electronics sector (e.g. circuit board cleaning)
- Electrical sector (e.g. winding cleaning)
- Degreasing of metal surfaces
Chlorinated hydrocarbons (CHCs)
Chlorinated hydrocarbons are a subgroup of halogenated hydrocarbons in which one or more hydrogen atoms are replaced by chlorine. Examples of representatives of this group of substances include perchloroethylene, trichloroethylene and methylene chloride. The advantages of CHCs lie in their excellent dissolving power for industry-typical soiling and contaminants, they have no flash point and are easy and efficient to recycle by distillation.
In addition, they have a low boiling point and a high vapor density. Due to the almost unlimited distillation capacity, the closed circuit can be operated permanently in a solvent cleaning system. CHCs are of great importance for industrial component cleaning or parts degreasing, as even the smallest parts and a wide variety of materials can be optimally cleaned. Chlorinated hydrocarbons are used, for example, in the cleaning of: turned parts, precision parts, stamped parts, deep-drawn parts, coolers and assemblies, as well as parts from precision mechanics and electroplating.
Application areas:
- Polar and non-polar contaminants are dissolved
- Cleaning of different materials (e.g. metal and plastic compounds)
- Temperature-sensitive parts
- Electronics sector (e.g. circuit board cleaning)
- Electrical sector (e.g. winding cleaning)
- Degreasing of metal surfaces
Isoparaffins
Isoparaffins are hydrocarbon mixtures (mixture of linear and/or branched aliphatic hydrocarbons; C9 – C13), where we recommend our product G60 Spezial in the solvent cleaning system. In general, the flash points for these solvent products are in the range of 55 to 65°C, which corresponds to a “boiling point range” of approx. 180°C to 220°C. Isoparaffins are almost aromatic-free compounds and virtually odorless. They are suitable for removing oily residues on metal surfaces and are therefore considered relatively good degreasing agents for a variety of applications, including outside of a solvent system.
However, the solubility of polar substances in hydrocarbon solvents is low. If the contamination contains polar components such as residues from aqueous emulsions and/or polar additives from high-performance cutting fluids, the cleaning effect is often insufficient. It is also important to know that isoparaffins are generally not stabilized. Acids that get into the solvent as part of contaminants or decomposition processes can accumulate in the cleaning system and lead to acidification and corrosion of the parts being cleaned and the solvent cleaning systems without effective countermeasures being possible.
