Design Envelope 4382 Dualarm Pumps

Brand: Armstrong Fluid Technology
Does not ship to OH, United States

Pipe-mounted 2-pump unit with integrated intelligent controls for space-saving installation, superior energy performance, and full redundancy or parallel-pumping operation.
Features
  • Vertical In-Line design eliminates the need for inertia bases, housekeeping pads, and flex connectors and reduces piping requirement
  • 2-pump casing for reduced footprint
  • Integrated intelligent controls eliminate procurement, installation (incl. wiring), calibration and maintenance of differential pressure sensors
  • 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
  • Optional Parallel Sensorless control (patent pending) with best-efficiency staging of both pumps for additional energy savings
  • Shorter pipe runs for reduced system friction 
  • 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 dualArm design packs and ships more economically for less packaging waste compared to loose component shipping and assembly
  • Integrated intelligent controls – combined with perfect component match-up and tuning – make commissioning fast and easy
  • Integrated controls reduce radiofrequency interference and improve  electromagnetic compatibility
  • DualArm design 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

  • HVAC-system pumping; general purpose pumping; industrial/process pumping (water or glycol based) 
  • Armstrong Design Envelope Pumps with integrated controllers are OSHPD pre-approved!
