Design Envelope 4300 Variable Speed Pumps

Category: HVAC Pumps

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

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
  • Advanced seal design for zero lubrication and seal adjustments. Optional sediment filters or separators for extended seal life in contaminated systems
  • Single source-responsibility for optimum design and field supportIndependent operation through embedded Sensorless control or in conjunction with a building automation system (BAS)_
