In public utilities, commercial organizations, community endeavors, even other projects of municipal engineering, water supply system is usual. Water pressures vary in different locations of a distribution system. To remain constant pressure in a distribution system is the key to succeed.
With built-in PID controller
for closed loop control, the installation of V&T EcoDriveCN® frequency inverters has successfully offered constant pressure of water supply industry, meantime, automatically regulating the speed of flow, reducing the energy costs significantly, reducing the work load of the people.
Application cases of V&T EcoDriveCN® variable speed drives (frequency converters) with PID closed loop control for water treatment to reduce the power consumption: constant pressure water supply system, multi-pump water supply controller.
Some competitive advantages:
failure rate < 0.15%
