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.

Applications
The C212L-EZD and C212L-EZD-F are true dual evaporators speciˆcally designed for high e€cient chiller systems dedicated to comfort applications, cooling-industrial process, data centers. The evaporators are design to operate also in reversable systems in condenser mode, in co or counter current …ow conˆguration.
The models are characterized by di‚erent distributor system the make the evaporator optimized for the highdensity refrigerants. C212L-CZD is a true dual condenser for high density refrigerants that operate in high pressure level; Lower pressure version are also available: C212-CZD.
