Data Sheet

Micro Plate Heat Exchanger Type C212L-EZD, C212L-EZD-F and C212L-CZD

For more ecient Chillers

21% lower hold-up volume enables

signicant reduction in refrigerant charge.

The C212L-EZD is an evaporator optimized for high density refrigerants for use in high- eciency chillers with capacities of 200-450 kW. It’s available in dierent versions meeting the best performance for dierent 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” ow, which increases the heat transfer coecient. 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.

To meet demands for higher seasonal

eciency, the C212L-EZD is designed to work eciently and increase comfort in modern

commercial buildings without increasing the carbon footprint. Helping chillers perform more eciently, it reduces both energy costs and environmental impact. The low hold-up volume reduces the system refrigerant charge and oers valuable savings.
