Outstanding Energy-saving Technology Redesigned for Smooth and Better Air Discharge 1 Dual large-capacity inverter compressors Two independently controlled inverter compressors achieve high efficiency (for models U-120MF2U9/U120ME2U9 and above). 2 Enlarged heat-exchanger surface area with triple surface • The new large size heat exchanger features a 3-sided construction. Compared to the conventional 2 (upper/lower) compartment outdoor unit structure, the new model offers more efficient heat exchanging performance. Current model [MF1/ME1] New model [MF2/ME2] 6, 8 tons 6, 8,10,12 tons 3 Gas-liquid separation + oil separation for increased efficiency • Accumulator : Increases gas-liquid separation efficiency to reduce compressor pressure loss. • Oil separator : Efficiently separates and absorbs refrigeration oil to prevent it flowing into the heat exchanger. 4 Large air discharge area with new flush surface top panel. To reduce air resistance, instead of a tubular fan design, a new large flat fan guard design, flush with the top panel, is employed. This design lead to the improvements in air resistance, but also contributed to improved air resistance in a more attractive appearance. Current model [MF1/ME1] New model [MF2/ME2] 5 Newly designed curved air discharge bell mouth for better aerodynamics The new curved shape with integrated top and bottom assure smooth air discharge flow. Minimal swirling means an increased flow rate. Current model [MF1/ME1] New model [MF2/ME2] 6 High 0.32 inch W.C. external static pressure - large diameter fan (27-1/2") A large, newly-designed 27-1/2" diameter fan. High 0.32 inch W.C. external static pressure Max. 80Pa external static pressure maintains performance in winds around large buildings. Ideal for high-rise buildings. 7 ECOi EXTM
