Major breakthrough #1 : Constant-Current-Source
Problem: When an electronic descaling unit was installed in a large pipe (i.e., > 3 in diameter), the output power significantly dropped.
Major breakthrough #2 : Off-set coil
Problem: Induction is zero at the center of pipe, where flow velocity is maximum.
Solution: Off-set coil
Major breakthrough #3 : Pre-wrapped coil
Problem: Manual wrapping at site is unsafe and impractical.
Solution: Pre-wrapped coil
Offset and pre-wrapped coil with constant current source are integrated as shown below:
