Dry facts

The development of electronic wall drying systems goes a long way back. Russian researcher, Prof. Reuss discovered the underlying physical principles in 1806, when he discovered that water molecules would be attracted to the negative pole of a natural or artificial magnetic field.

Patents covering processes to dry walls have been in existence since 1935; initially electrical wiring would be built into the walls and then energized. The same effect can now be achieved more economically and more simply by using field generating equipment such as the EDS system.

Dry numbers:

  • The capillaries of a nut-sized pebble can cover 50 square meters when spread out.
  • The explosive effect of salt crystals can reach 2 metric tonnes per square centimetre.
  • Water will be drawn higher in a thinner capillary. A capillary of 0.01 centimeters in diameter will draw water to a height of 14.8 centimeters.
  • Moisture in solids is measured either in relation to its gross weight or to volume. 1 % moisture in a brick wall with a gross weight of 1,600 kilograms represents 16 liters of water per cubic meter, 12% moisture represents 192 liters.
  • 12% moisture content in a wall reduces its thermal insulation capacity to 20%.
