Armstrong Fluid Technology has announced that its COMPASS R20-75 circulator is available in a stainless steel construction.

Designed for use in potable water systems, the stainless steel model features a dry rotor design, as well as variable speed Design Envelope technology, Armstrong iECM motors, and quadratic control to minimize both energy costs and long-term operating costs for owners.

The quadratic control algorithm offers improved operating efficiencies, and system energy savings are possible with the 0-1V dc input signal connection to external systems.

The COMPASS R is a direct performance replacement for nine competing circulator models and a bolt-to-bolt match for several installed circulators.

Other features of the stainless steel COMPASS R circulator include:

  • Optimized hydraulics with a high-efficiency dry rotor design
  • Posi-start technology provides smooth starting and automatic de-blocking
  • Onboard control panel for selection of the appropriate operations mode and flow
  • Release latch for adjustment of the display orientation and repairability
  • Front-facing terminal block with a wiring chamber
  • Replaceable mechanical seal and any other circulator part required
  • Complies with EEI<0.22, NSF-372
