Under normal ambient pressure, water boils (evaporates) at 100°C. This initially creates wet steam, i.e., steam with a very high water content. If this boiling process takes place in a closed system (steam boiler), higher temperatures are reached, and thus drier steam is also achieved. The higher the temperature and pressure, the drier the steam. If the water content approaches zero, one speaks of saturated or dry steam. Dry steam is achieved in the MediCleanTec Micro Cleaner at 9.5 bar and 180°C.
The quality of the steam makes all the difference: less visual impairment, better penetrability, quick and residue-free drying. The high surface tension of water that is always in drop form stands in the way of any cleaning process. In order for the water to still be able to get under dirt, it is always used in conjunction with a cleaning agent when cleaning.
Steam, that is, condensed water, no longer has any surface tension and can therefore be used to clean without chemicals. The steam molecules, which are tiny in comparison to those of water, penetrate even the smallest microstructures on the surfaces and therefore achieve an excellent cleaning result.
