Not every production requires an automated washing plant with a full conveyor line. Sometimes the effective and rapid removal of contaminants from workpieces can be achieved more simply - more cheaply, without extensive infrastructure and unnecessary features. The key is to match the equipment to the real needs of the process, not to a catalogue. If the requirements are greater - for example, chemical surface preparation is involved - it is worthwhile to provide for the ability to work with more aggressive agents from the outset. It's not necessarily a big design difference, but it gives you much more flexibility when more difficult details or new orders arise. It's an approach for those who don't want to overpay, but want choice - and equipment that actually works where it's needed.
