Patented pump system technology reduces energy use by over 60%
Queensbury, N.Y. - Kadant AES, a division of Kadant Inc. (NYSE:KAI), a leading global provider of process solutions, offers the UNiGY® pump-control system, an exclusive and patented control technology for high-pressure positive displacement process pumps. Equipped with UNiGY PhD(TM) (Pump-modeling hydraulic Drive), the system employs mathematical models to dramatically improve energy efficiency, process control, and system availability of positive displacement process pumps applied to processes where flows and pressures vary.
An elegantly simple system, UNiGY technology employs intelligent pump-control software to produce the precise flow rates and pressures demanded by the application, and no more. The UNiGY PhD continually senses demand and manages pump speed and applied torque as required to satisfy variations in process demand, significantly lowering energy consumption and noise.
For processes where hydraulic demand is intermittent, the UNiGY system can reduce maintenance costs and extends pump life. The UNiGY drive achieves this by slowing pump speed when flow is not required while using torque management technology to maintain desired system pressure at all flow rates.
UNiGY technology can be easily retrofitted into existing process systems and incorporated into new installations. The technology reduces system complexity by eliminating the need for flow and pressure sensors and control valves.
About UNiGY® UNiGY®, is a patented technology that utilizes pump-modeling software in closed-loop Flux Vector Drives for hydraulic power generation and to monitor and control high pressure positive displacement pumps. Not to be confused with VFD technology, UNiGY PhD(TM) (Pump-modeling hydraulic Drive) technology provides precise control of both pressure and flow. Developed under a grant provided by the New York State Energy Research and Development Authority (NYSERDA), UNiGY technology reduces energy use, simplifies system design and provides valuable pump and systems diagnostics which significantly reduces maintenance and downtime expense.
