This type of washer is targeted at parts that cannot be sufficiently or reliably cleaned with manual labor, such as hoses, pipes, gaskets, and fittings. Immersion parts washers are the preferred cleaning method for disassembled parts that must be placed in baskets or processes that require a long soaking period.
To accommodate diverse cleaning needs, immersion parts washers are manufactured with several different performance designs, from very simple (dirt, grime) to quite aggressive (mold release agents, paint). Examples of the main type of washing methods include: soak, fluid agitation, parts agitation, and heated water-based solution.
The newest type of immersion parts washer to emerge is the ultrasonic immersion parts washer. This type of washer, designed specifically for use in the biotechnology and pharmaceutical industries, cleans using tubular transducers that generate high-frequency vibrations, or sound waves, to dislodge soils in hard to reach crevices. These waves can be manipulated to make the washer operate in a number of different ways.
Immersion parts washers range in operation from manual to fully automatic. Capabilities that can be automated include: cycle time and cycle steps, water fill level, chemical addition, temperature control, flow control and draining operations, final rinse verification, alarm monitoring, and cycle reporting.
Additionally, they may use water-based or solvent cleaners. However, heated washers cannot be paired with solvent cleaners. Water-based cleaners offer the advantage of suitability for virtually any organic or inorganic soil, including greases, oils, carbons, hard water residue, epoxies, oxides, paints, corrosion, plating salts, rust, and smut. They are most effective when heated, and they are removed by a simple water rinse.
Solvents, on the other hand, are ideal for cleaning metal, plastics, and painted surfaces. They easily remove motor oil, grease, water-soluble oil, as well as gummy deposits normally unaffected by water-based cleaners. Immersion parts washers have many configuration options, such as portable or stationary, side jets, end jets or both, single or multi compartments, semi or fully automated controls, and more. Immersion parts washers are invaluable in many markets, include injectable liquids, APIs, oral solid dosage, cosmetics, nutraceuticals, OTCs, and animal health. Popular applications include pump rotors, impellers, tubing, filter housings, needles, diaphragm valves, filler components, bowls, hoppers, and belting. Immersion parts washers are great tools!
