In industrial parts cleaning, wet media are used in 70 to 90 % of all cleaning processes. Wet media include aqueous solutions – similar to detergents we use to wash our dishes or laundry – as well as nonaqueous solvents. For each cleaning task, project engineers must choose the best wet medium, taking into account ecological and economic considerations. Workpieces and parts are produced in finetuned production processes that often require the use of special consumables and process chemicals. Parts are generally made from specific materials, and their contamination after machining is determined by the processes they have undergone. When assessing the environmental impact of cleaning media, one sometimes comes to surprising conclusions. First of all, the energy input and use of resources must be assessed.

KLN manufactures various cleaning machines acc. to ATEX (ATmosphère EXplosibles) for the use of combustible liquids. The cleaning machines can be used separately or in combination with other methods. The cleaning tanks must be operated at a well ventilated place. The combustible cleaning agent can be filled in directly into the tanks. The ultrasonic generators are set up separately. A safety thermostat (setting 15°C below the flash point) controls the adherence to a max. temperature and in case of excess temperature it switches the machine off. The cover included in the delivery avoids emissions from the tank during standstills. The machines can also be used in connection with aqueous cleaning methods. Options: • heating • extraction • cooling tube • ultrasonic frequencies 30 and/or 40 kHz • automation system • product carrier

The less space between the parts, the more difficult it is to remove particles and contaminants with a wet medium. The handling of the parts and the design of the parts carriers are therefore important aspects for optimised cleaning. Wet media are used in units with 1, 2, 3 or even more baths where the parts are cleaned and rinsed, and, if required, treated with preservation agents.

By documenting the required technical cleanliness and the processes of your chosen method, you obtain an unrivalled level of process safety at an early stage. You know that you will achieve the necessary technical cleanliness long before you integrate the cleaning unit into your production plant.

Bring your dirty parts to the PERO Centre of Competence. The cleaning experts of PERO will advise you in how these parts can best be cleaned. You can then perform a series of tests in order to identify the optimised cleaning process for your parts. Cleaning tests free of charge, using your own parts; including documentation Evaluation of cleanliness analyses Gaining new insights into own cleaning processes

To develop a cleaning solution that meets the specifications, PERO engineers identify the best wet cleaning method and devise the sequence of the process steps as well as the process parameters. The effectiveness and efficiency of the chosen process is then verified by test runs performed at the PERO Centre of Competence.

To achieve the required technical cleanliness, the parts must be correctly handled and placed in the cleaning unit. This is normally done by using special parts carriers that can withstand the cleaning conditions.

After cleaning, parts are normally dried. Efficient drying keeps cleaning medium consumption low, and thus helps protect the environment. In addition, drying effectively prevents recontamination and corrosion. When drying tightly packed or porous parts, drying at atmospheric pressure might not be effective, so that drying under vacuum is the only option.

Hot solvent vapour is applied to the surfaces of the parts where it condensates, forming a solvent film in which dirt is dissolved. As the solvent condensate runs down along the parts, it takes with it the dirt particles (dust, chips, etc.), leaving behind clean surfaces. This physical cleaning effect results in thoroughly cleaned surfaces.

Sound waves generated by an oscillator agitate the wet medium. This leads to cavitation bubbles that implode at a high frequency and result in hydraulic impacts. These impacts combined with microflows flush particles and pigments off the parts. The costs of ultrasonic cleaning are primarily determined by the processing time. Low ultrasonic frequencies remove coarse dirt, while high ultrasonic frequencies are used to eliminate fine dirt from parts.

The parts are immersed in the wet medium. Dirt is dissolved from the surface by the heated wet medium. By moving the parts while immersed, cleaning is assisted by a mechanical effect. In industrial parts cleaning, the surfaces are then normally rinsed and dried.

The wet medium is sprayed through nozzles onto the surfaces of the parts. Particles are removed from the parts by kinetic energy, and then washed away. The cleaning result is primarily determined by the position and shape of the nozzles, the spray pressure and the volume of media applied to the parts. In industrial parts cleaning, the surfaces are then normally rinsed and dried.

The cleaning process must be designed to eliminate specific contaminants and particles from machined workpieces and parts in order to achieve the required technical cleanliness. For the wet cleaning of parts, the four parameters of the Sinner's Circle need to be combined and adjusted for optimised efficiency. PERO units offer efficient cleaning mechanics and reliable process control. According to the Sinner's Circle, the cleaning result is determined by four basic variables. By adjusting and combining these interrelated variables, it is possible to optimise any cleaning process. Good mechanical design of a cleaning unit optimises the mechanics of the process, which generally means that cleaning is completed in less time and with less resources.

Acidic, neutral or alkaline wet media Aqueous media remove dirt particles from surfaces and rinse them off. Aqueous detergents disperse particles, and form or separate emulsions. They act on the surfaces of parts. If required, aqueous media can be used to alter the surface properties of parts by passivation (phosphatising), pickling, etc. In all applications, the treatment of the medium itself is of crucial importance. Aqueous media are powerful detergents. Solvents are wet media that are able to dissolve substances without actually reacting with them. The most commonly used cleaning solvents are hydrocarbons and modified alcohols with a flash point > 55°C, and halogenated hydrocarbons. Solvents remove dirt particles from surfaces and rinse them off. Advantages Short cycle times, energyefficient drying, low solvent consumption, long medium service life and easy treatment.
