COMPASS circulators offer high flow capacity and eight optional control modes that deliver superior energy efficiency for lower operating costs. The SSU Model also features a threaded union connection that is easy to adapt to copper, PEX or CPVC plumbing.
“The versatile COMPASS SSU can replace a wide range of fixed-speed circulators and is very easy to select, install, and commission,” said Andy Januszewski, Marketing Manager with Armstrong. “Design Envelope technology, combined with ECM motors, saves 50% or more energy and related carbon emissions over fixed speed circulators.”
Other features of the new COMPASS SSU include: Eight operation modes including an “Auto” algorithm, four sensor-less modes, and three fixed modes, 50Hz and 60 Hz designs, up to 20 USgpm (1.26 L/s) flow OR up to 20 ft. (6.1m) head, and 5 W to 45 W power range.
