Commissioning and testing has been a core component of the consulting
and design work developed at JDA Consulting Engineers since 1990. Our
firm’s experience suggests that VSD technology has become a panacea for
solving the complex design issues that relate to centrifugal pump
selection. As JDA’s team commissions large, complex mechanical plants,

Rather than providing the precise control of flow and pressure or
reducing energy consumption and demand, the VSDs appear to be “stuck”
at a single speed.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
