It guarantees maximum technical cleanliness, irrespective of the degree of contamination of the parts. The NEPTUNfeatures two baths and has been designed for reliable intermediate and final spray cleaning with aqueous media. Its touch panel control enables to devise and run customised cleaning programmes. Cleaning with aqueous media (acidic, neutral or alkaline) 660 x 480 x 300 mm 4 x 480 x 320 x 200 mm Powerful spray cleaning Universal machine Suitable for any cleanliness level from light dirt removal to high technical cleanliness Available as 2bath unit with loading of the unit via Manual loading table Manual charging unit Automatic charging unit

The TWT combines a number of cleaning methods in a single unit. Through immersion any spray cleaning with alkaline, neutral or slightly acidic aqueous media, it caters for a wide range of parts and meets even the most stringent requirements regarding technical cleanliness. The cleaned parts are dried under vacuum for extra fast processing. All machine components that come into contact with media are made in stainless steel, allowing for the use of fresh and demineralised water.

The ROBOMAT models are designed for the cleaning of a wide range of parts and cater for various levels of cleanliness. Operators can place workpieces and parts of various size and geometry in the processing chamber of the sturdy unit where they are spraycleaned to a high cleanliness level. The model with two baths is particularly suitable for surface cleaning prior to painting and final assembly. Suitable for cleaning, phosphatising and rinsing.

The compact KDA tunnel units cater for high throughput rates combined with excellent cleaning and drying. They have been designed for the treatment of parts of many different geometries and sizes. The KDA is available with belts of various widths (200/500/650 mm) and a range of features and accessories to cater for many different cleaning tasks. The KDA is available as 1, 2 and 3bath unit.

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.

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.

Wet media differ greatly as regards safe handling, service life and cost of treatment.

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.

For all cleaning methods, operators must comply with the applicable statutory regulations at local, national and international level. The handling and the treatment of the cleaning media are two important aspects that must be taken into account when assessing cleaning tasks and suitable methods.
