Featuring Advanced Variable Speed Design with ECM Motors

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

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

The innovative quadratic control algorithm offers operating efficiencies that are better than standard variable speed solutions, and even greater system energy savings are possible with 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 many installed circulators.

Other innovative 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 easy selection of the appropriate operations mode and flow
• Release latch for easy adjustment of the display orientation and repairability
• Easy-to-access front-facing terminal block with a large wiring chamber
• Replaceable mechanical seal, and any other circulator part required
• Complies with EEI˂0.22, NSF-372
