Micro plate heat exchanger

Type C212L-EZD, C212L-EZD-F and C212L-CZD

21% lower hold-up volume enables significant reduction in refrigerant charge.

The C212L-EZD is an evaporator optimized for high density refrigerants for use in high-efficiency chillers with capacities of 200-400 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.

To meet demands for higher seasonal efficiency, the

C212L-EZD is designed to work efficiently and increase comfort in modern commercial buildings without increasing the carbon footprint. Helping chillers perform more efficiently, it reduces both energy costs and environmental impact. The low hold-up volume reduces the system refrigerant charge and offers valuable savings.

Features : y Improved heat transfer - equals higher efficiency chillers y Reduced water side pressure drop – equals higher efficiency chillers y Minimal hold-up volume - equals less refrigerant charge y Smaller footprint - enables more compact chillers y High heat transfer y Minimal refrigerant charge - equals a reduced

Applications

Portfolio overview

The C212L-EZD and C212L-EZD-F are true dual evaporators specifically designed for high efficient 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 flow configuration.

The models are characterized by different distributor system the make the evaporator optimized for the high-density 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
