Saturated Steam can be divided in saturated dry steam and saturated damp steam.
SATURATED DAMP STEAM
Saturated damp steam is water steam in which water is present in the form of micro droplets.
SATURATED DRY STEAM
Saturated dry steam is deprived of micro droplets and is obtained with steam producing boilers heated up at 150-180C at a pressure of 6-10 Bar.
REA steam cleaning generators have pressures up to 12 Bar and can produce this second type of steam.
