Data Sheet
Micro Plate Heat Exchanger
Type C118L-EZ and C118L-EZ-F
For more e€cient Chillers
21% lower hold-up volume enables significant reduction in refrigerant charge.
The C118L-EZ and the C118L-EZ-F are evaporators optimized for high density refrigerants like the R410A and its replacement R454B and R32 for use in high-e€ciency chillers with capacities of 70-250 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 coe€cient. At the same time, inheriting from the dimple features, C118L-EZ reduces the water side pressure drop and the amount of material used. In the reversible mode of the chiller as a condenser, C118L-EZ also has outstanding performance.
To meet demands for higher seasonal e€ciency, the C118L-EZ is designed to work e€ciently and increase comfort in modern 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 offers valuable savings.
Features:
• Improved heat transfer - equals higher e€ciency chillers
• Reduced water side pressure drop – equals higher e€ciency chillers
• Minimal hold-up volume - equals less refrigerant charge
• Smaller footprint - enables more compact chillers
• High heat transfer and minimal refrigerant charge - equals a reduced CO footprint

Portfolio overview
C118L-EZ: Evaporator optimized for R410A, R452B and R454B
C118-EZ: Evaporator for medium density refrigerants PS: 30bar
C118L-EZ -F: Evaporator optimized for R32
Applications
The C118L-EZ and C118L-EZ-F are single circuit 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 flow conˆguration.
The models are characterized by different distributor system the make the evaporator optimized for the highdensity refrigerants. Even if equipped with distributor device, the C118L-EZ and C118L-EZ-F can run properly in condenser mode.
