21% lower hold-up volume enables signifucant reduction in refrigerant charge. The C212L-EZD is an evaporator optimized for high density refrigerants for use in higheffiiency chillers with capacities of 200-450 kW. It’s available in different versions meeting the best performance for different refrigerants like the R410A or its replacement R32, R452B and the R454B. Corresponding model for condenser duties is the C212L-CZD. 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, C212L-EZD reduces the water side pressure drop and the amount of material used. In the reversible mode of the chiller as a condenser, C212L-EZD also has outstanding performance.
