Advantages Of Johnson Screen
Large % open area
Due to continuous slots and special design, the Johnson
Screen has more than double % open area for water to enter compared to slotted strainer for same slot opening. More open area means lesser Entrance Velocity and lesser Frictional Loss. Even lesser length or small dia. of screens can be used without compromising on total open area.
Better Sand Control
Due to wide range of accurate slots down to 0.25 mm (1/100”) or even lesser in special cases, much better sand control can be achieved without loosing much on open area. Reduced entrance velocity makes the flow more laminar and reduces turbulance, which further improves the sand control.
Lesser sand pumping – Lesser pump maintenance – longer tube well life
Inwardly widening slots do not allow any particle to get stuck inside the slot and cause clogging. Thus the slots are non-clogging. This ensures no reduction in discharge over a period of time due to clogged slots. This means Longer Effective Life of Tube Well. Moreover, due to reduced entrance velocity the formation of incrustants is also very slow.
