In the 1990s, the German company Seifert introduced an innovative surface steaming technology – large-surface steaming under steel or aluminium hoods. Compared with sheet steaming, this method has the advantage of a much higher steam transfer. Instead of 4kg per hour per square metre under the sheet, the hood allows for over 30kg per hour per square metre. The result is a significant reduction of the steaming time and also in heating oil consumption. Energy consumption Depending on the steaming time and soil characteristics, you need 0.3 litres of heating oilper square metre to reach 8-10cm steaming depth, or 1 litre of oil to reach 25-30cm depth. You can achieve up to 85°C soil temperature with this method. With hood steaming, you therefore save up to 50% in heating oil compared with sheet steaming. Rules of thumb: 1. The longer the steaming time, the higher the energy losses and therefore the energy demand per square metre. 2. The steaming time for 10cm steaming depth is about 8 -12 minutes. 3. You can achieve 30kg steam per hour and square metre under a normal steaming hood*. Know how! Tips and tricks Our special high-quality MSD steaming hoods are made of steel or aluminium. Their lifecycle is extremely long. They are used in greenhouses, tunnels and outdoors as they are very reliable.
