Facilities predominantly using these drives may face concern from power utility companies.
VFDs
There are numerous factors to consider to ensure the best performance with this technology.
An influent pump station in Washington incorporated control technology that improved system efficiency and energy savings.
The changing landscape of hydraulic drives is leading many fluid power specialists to quickly adapt to VSDs.
With the standard, specifying design engineers, owners and energy managers can compare VFDs on an equal basis.
Louisiana's Sabine River Authority incorporated this VFD alternative to divert 141 million gallons of water per day.
VFDs can reduce energy consumption and water loss in variable pumping systems.
To ensure the best system setup, end users must first consider operating conditions, then conduct thorough cost-benefit calculations.
