Design Envelope 4380

  • Summary
  • Applications

    HVAC-system pumping and control; general purpose pumping; industrial/process pumping and control (water or glycol based)

  • Description

    Pipe-mounted UL 778 pumping unit with integrated intelligent controls for space-saving installation and superior energy performance. Saves up to 75% in energy over comparable traditional constant speed or variable frequency operated pump installations. Remote services through internet to enhance reliability and sustain optimal performance over life of pumps.

  • Materials
    • Ductile iron e-coated casing
    • Stainless steel impeller
    • Sintered silicon carbide mechanical seal
  • Configuration

    On-board Intelligent Variable Speed controls with Sensorless control. Controls enclosure IP55 or IP66 for outdoor applications. 0.75-7.5 kW range standard with iECM motors that reduce losses by more than 20% over NEMA Premium efficiency. Network capable for remote performance management services.

  • Performance Range

    1.5 to 28 L/s (25 to 450 USgpm) flow; 3 to 48 m (10 to 160 ft) head (composite curves available)

  • Temperature

    121oC (250oF)

  • Power

    0.75 kW to 7.5 kW (1 hp to 10 hp)

  • Size

    40 mm to 150 mm (1.5" to 6”)

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.
  • 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
  • Shorter pipe runs for reduced system friction
  • Vertical In-Line configuration allows less disruptive pump service (casing stays in place)

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)
