Sandwich-type steaming is the most effective and energy-efficient surface steaming method. In this further development of the hood steaming method, the hot steam penetrates deeper into the soil. The steam is led under the hood via a number of hollow pins, each of which has several exit holes. These pins penetrate the soil up to a 25cm depth. Soil temperature of more than 85°C can be achieved under the covered surface very evenly and quickly with this method. Sandwich-type steaming is efficient for soil depths between 10 and 25cm. Energy consumption The energy consumption is very low due to the shorter steaming time, which is radically reduced because of the deep penetration of the hot steam. At 25cm steaming depth, you can count on heating oil consumption of merely 0.6 litres per square metre to reach up to 85°C depth temperature within just five minutes. At steaming depths beginning from 10cm, sandwich-type steaming saves about 35% in energy compared with normal hood steaming.The energy consumption is very low due to the shorter steaming time, which is radically reduced because of the deep penetration of the hot steam.
