Design Envelope 4302 Dualarm
Brand: Armstrong Fluid TechnologyPipe-mounted 2-pump unit with integrated intelligent controls for space-saving installation, superior energy performance, and full redundancy or parallel-pumping operation. Saves up to 75% in energy over comparable traditional constant speed or variable frequency operated pump installations.
Features- Vertical In-line design eliminates the need inertia bases, housekeeping pads, and flex connectors and reduces piping requirements
- 2-pump casing for reduced footprint
- Integrated, intelligent controls eliminate the need for procurement, installation (incl. wiring), calibration and upkeep of differential pressure sensor
- 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
- 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 pumping installations
- Available with Parallel Sensorless control (patent pending) to provide best-efficiency staging of both pumps for additional energy savings
- Shorter pipe runs reduce system friction
- Integrated intelligent controls – combined with perfect component match-up and tuning – for up to 75% lower energy consumption and carbon (greenhouse gas) emissions
- Available with Parallel Sensorless control (patent pending) for best-efficiency staging of both pumps leading to additional energy savings
- Integrated intelligent controls – combined with perfect component match-up and tuning – for fast and easy commissioning
- Integrated intelligent controls for reduced radio frequency interference/ improved electromagnetic compatibility
- Single source-responsibility for optimum design and field support
- DualArm pumps are designed for full redundancy in case of emergency or routine servicing (each pump can be individually isolated from the system with the second pump still operating)
- ETL Listed - conforms to UL STD 778
- Certified to CSA STD C22.2 NO.108
