The 0034ePlus is a high-performance, variable speed, wet-rotor circulator with high-efficiency ECM permanent magnet technology. With an intuitive digital interface, its variable speed performance curves are equivalent to the Taco 009, 0010, 0011, 0012, 0012 3-Speed, 0013, 0013 3-Speed & 0014. Ideal for largeresidential and light commercial hydronic heating, chilled water cooling and domestic hot water systems. The 0034ePlus reduces power consumption by up to 85% compared to equivalent AC permanent split capacitor circulators.
