Steam Cleaning

Setting the Benchmark in Eco–Friendly Part Cleaning

Depending on the cleaning task, the water is thus heated to a temperature between 135 and 280°C. Its conversion to steam takes place before the water is pumped from the piping to the cleaning nozzle. Unlike conventional boiler systems, the flow-through steam generating method ensures that steam is made available in constant amounts and quality, thus bringing unvarying steam properties to the cleaning task. The water and steam flow rates as well as heating power can be accurately adapted to the cleaning application via the system’s programmable logic controller (PLC) which also monitors and controls these parameters

permanently.

Cleanliness Due to Interaction of Steam and Air

The system’s outstanding cleaning performance is owing to the interaction of saturated steam with a high velocity airflow. As the steam jet exits the nozzle, it is enshrouded all around by heated air accelerated to a very high velocity and thus focused directly onto the surface to be cleaned. Any intermixing between the two media is prevented by the high flow velocity of the air and the properties of the steam.

For an optimum cleaning result the moisture content of the steam can be accurately adapted to the cleaning task or specific contamination type. Thus, for removing oil, wet steam is applied to modify the oil viscosity so that the oil will be atomized into ultra-fine droplets. These are then blown off the part surface, along with particulate contaminants, by the airflow. Drying is provided by the highvelocity airflow as well.

Fast and Cost-Efficient Cleaning

The system’s cleaning process is commonly performed in one or two steps. This translates into shorter cleaning cycles compared to conventional methods, and productivity is enhanced as a result. But this space-saving steam cleaning technology also excels in cost efficiency.

On the one hand, it involves much lower investment and on the other, it provides operating cost savings since no chemical cleaning agents are needed and no bath treatment and filtration equipment is required. Its exceptional ease of

maintenance and high availability are further benefits speaking in favor of the process.
