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
