21% lower hold-up volume enables significant reduction in refrigerant charge. C117L-EZD is an evaporator optimized for R410A for use in high-efficiency chillers with capacities of 50-200 kW, and standard efficiency chillers with capacities of 50-250 kW. The Z-pattern channel plate technology pushes the performance of heat exchangers to the limits by fully mixing the liquid and gas refrigerant through a “zigzag” flow, which increases the heat transfer coefficient. At the same time, inheriting from the dimple plate pattern of the previous generation of MPHE, C117L-EZD reduces the water side pressure drop and the amount of material used. In the reversible mode of the chiller as a condenser, C117L-EZD also has outstanding performance To meet demands for higher seasonal efficiency, the C117L-EZD is designed to work efficiently and increase comfort in modern commercialbuildings without increasing the carbon footprint.
