What It Isn't
- UNiGY® is distinctly different from VFDs that operate with a velocity loop. UNiGY uses torque management to control pump pressure output.
- VFDs rely on downstream instrumentation and sensors for feedback control whereas UNiGY® uses the pump modeling for feed forward control.
- The UNiGY® technology platform makes it unnecessary to use complicated mechanical methods such as pressure compensated Variable Displacement Pumps.
-
UNiGY® is far more than a simple motor starter or drive. It uses high speed processing to integrate soft start, motor control and pump diagnostic features that are unavailable in other drive technologies.
- The UNiGY® technology platform negates the use of mechanical flow controls for hydraulic power management.

What It Is
- Torque management methodology
- Feed-forward positive displacement pump modeling
- No sensors/transducers necessary for closed loop process control
- Open loop control with minimized hydraulic system complexity
- Built in Pre-emptive Diagnostics based on pump models
- Exclusive and patented control methodology using ITD
| ITD: ‘Infinite Turn-Down’. A UNiGY system designed to allow the operating flow and/or pressure to be reduced from the maximum design flow/pressure to zero. |
| LTD: ‘Limited Turn-Down’. A UNiGY system designed to allow the operating flow/pressure to be reduced from the maximum design flow/pressure to a specified minimum amount. |
LTD pump and HY-DYNE motor/drive system
- Six generations of development
- State of the art, leading edge drive technology using DSP (Digital Signal Processing)
- Energy savings typically of 60% - or more
- More precise pressure and flow control - at the pumphead
- Hydraulic cooling requirements reduced - or eliminated
- Reduced maintenance and operating costs
- Reduced noise levels [<80dba]
- Virtually eliminates pump ripple
- Over 100 production-scale installations
- Applicable to new systems or retrofits
- Scalable to any system size
