AquaMotion’s AMRe ECM heating circulator features all-metal construction and stainless replaceable cartridge with Iron Guard. The circulator’s permanent magnet rotor uses only 45 W with a high performance of 20’ x 18 gpm. Its stainless cartridge can be replaced, and the Iron Guard design protects against black iron oxide and contaminants. The circulators feature fully automatic operation, no programming, no buttons to push, no speed setting, an LED light and Watt display, a 10’ detachable line cord and cord connector, a flange with nut capture and a built-in check valve. The AMRe is also U.S.-built, tested, and ETL-listed.
