How do you size a VFD?
Confusion often surrounds the proper sizing of variable frequency drives (VFDs), and sometimes, knowing when and how to choose one may be difficult. Actually understanding what a VFD does might make this decision easier and the requirements…
The drives strategy that saves energy and water loss
As the cost of energy and water and wastewater services continues to rise, operators are looking for ways to reduce the costs of these basic, yet crucial utilities. Proposed energy-efficiency standards from the U.S. Department of Energy (DOE) and…
A Lifetime of Confusion
In several discussions that I had with customers over the years, the topic of expected lifetime has come up. The concern for a product’s reliability as expressed by Lifetime is a natural part of the evaluation. Lifetime…
VFD Speed Control Saves Energy
The energy saving potential when a frequency converter is used depends on the type of load being driven and the optimisation of the efficiency of the pump or the drive by the frequency converter, as well as how much time the system operates…
VFDs Maintain Constant Water Pressure and Eliminate Water Hammer
To handle growing water demands, the City of Cottonwood in the arid central highlands of Arizona devised a strategic water management plan that included creating a modern municipal water system with monitoring, control and pumping technology. The…
