Description
Benefits & Features
Lowest installed cost
- Vertical In-line design eliminates the need for inertia bases, housekeeping pads, and flex connectors and reduces piping requirements.
- Integrated intelligent controls eliminate separate mounting of variable frequency drive (VFD) as well as procurement, installation (incl. wiring), calibration and upkeep of differential pressure sensor.
- Vertical motor positioning requires up to 60% less floor space compared to other pump configurations.
- Expertly staggered product line for perfect pump match-up and selection especially in retrofit situations.
- Superior energy performance qualifies for significant cost recovery under utility and government rebate programs.
- Design Envelope selections frequently recommend a smaller motor and/or pump which reduces installed cost.
Lowest operating cost
- Integrated intelligent controls – combined with perfect component match-up and tuning – for up to 75% in energy savings over traditional constant speed and variable frequency operated pump installations.
- Split-coupling design for easy seal service without removal of pump or motor.
Lowest environmental cost
- 75% decrease in energy consumption reduces operational greenhouse gas emissions at equal ratio.
- Elimination of inertia bases, housekeeping pads, flex connectors and superfluous piping avoids all procurement related environmental impacts. (material, energy, carbon)
- Equipment downsizing mitigates environmental impacts associated with procuring unnecessarily large equipment.
- Integrated design packs and ships more economically for less packaging waste compared to loose component shipping and assembly.
Lowest project and operating risk
- Integrated intelligent controls for fast and easy commissioning as well as reduced radio frequency interference/ improved electromagnetic compatibility.
- Optional performance management for early warnings, online trending and analysis, and reports and summaries.
- Optional sediment filters or separators for extended seal life in contaminated systems.
- Single-source responsibility for optimum design and field support.
- Independent operation through embedded Sensorless control or in conjunction with a building automation system (BAS)
- ETL Listed – conforms to UL STD 778
- Certified to CSA STD C22.2 NO.108
