Yes, the steam can be dry!

If someone tells you “steam” you’re probably thinking “humidity”. But steam can be dry, and this paradox explains the technological prowess of the Dry Steam Cleaner Vapodil.

Let’s give you some explanations!

When you heat water up and reach the boiling temperature (100 °C/212 °F at normal pressure), water turns from a liquid to a gaseous state, resulting in steam. It only requires for this steam to cool down slightly for some of the water molecules to condensate. They form droplets which remain dispersed in the steam: this is the humid steam.

An example for better understanding

Let’s use the example of a kettle. Because of the heat transmitted by the heated element, the temperature of water rises: the water absorbs the heat progressively, the H2O molecules get agitated, and the water starts to boil.

Once a sufficient quantity of energy has been absorbed, some of the molecules vaporizes. The steam escaping from the spout of the kettle is the sign of a heat loss, the dry water steam loses some of its energy when it gets in contact with the ambient air, colder. It then becomes humid steam, because it contains a mixture of water in a liquid state (the small droplets) and in a gaseous state (the vapour).

What about the dry steam from the Dry Steam Cleaner?

Now imagine that we keep on heating this steam well above the boiling point. By exceeding 110 or even 120°C (248 °F), its thermal energy increases. This superheated steam is  dry steam, which contains no liquid molecules, only water molecules in the gaseous state.

This is the performance  achieved by the Dry Steam Cleaner Vapodil : heating up the steam constantly to prevent it from immediately condensing on contact with the ambient air or a cold surface.

A cutting-edge technology

This high technology allows the continuous production of very hot and dry steam,which is completely safe for the user! The jet contains a pressurized mixture of approximately 93% dry air and 7% water steam, which means that very little water is consumed.

There are no water droplets in the jet, only steam.  However, droplets can sometimes appear by condensation of the steam on a colder surface (a glass pane, for example).
