VFD ( Variable Frequency Drive )
HL's EIC series are innovative variable frequency drives designed not only to control ON/OFF of a water pump, but also automatically regulate pump speed based on actual demand
of water flow and pressure. In this way, constant flow and even pressure are maintained at end user's side and in the meantime, pump life is maximized and electricity bill is saved.
In addition to dry-run protection and auto restart function during a water shortage, EIC series also protect the pump from excessive electrical current and power surge.
