What is steam and how does it work in cleaning?

Steam is visible, moist vapour that is produced when liquids are heated—usually by heating water. Steam plays a central role in industrial cleaning, especially in the form of saturated steam generated under pressure and high temperature. A distinction is made here between saturated moist steam and saturated dry steam, which differ in terms of water content, temperature and cleaning effect.

Saturated moist steam describes a state in which water exists simultaneously in liquid and gaseous form. This steam still contains micro-water droplets. It is produced in boilers at temperatures of approximately 140 to 165 degrees Celsius and a pressure between 6 and 10 bar. The water content is about 5 percent. Moist steam is suitable for cleaning tasks where higher humidity is desired, for example for light soiling or for pretreatment.

Saturated dry steam is almost free of micro-water droplets and is therefore particularly efficient for precision cleaning and disinfection tasks. It is formed at temperatures above 180 degrees Celsius and a pressure between 10 and 12 bar. IproTech steam systems operate at 12 bar and 188 degrees Celsius – ideal for industrial applications that require thorough cleaning with minimal water usage.

Effect on contaminations

The high temperature combined with the physical energy of steam breaks down the molecular bond between dirt and the surface. In this manner, grease, oil, dust and other residues are effectively loosened and removed. At the same time, temperature has an antibacterial effect and kills microorganisms on the treated surface. Due to low water content, the surface dries quickly and without leaving residues.

Benefits of steam application at a glance

• Effective removal of dirt without harsh chemicals
• Germicidal effect due to high temperature
• Surfaces dry up fast due to low water content
• No residues
• Suitable for complex geometries and hard-to-reach areas
• Environmentally friendly and economical
