Data Sheet

Micro Plate Heat Exchanger Type C118L-EZ and C118L-EZ-F

For more ecient Chillers

21% lower hold-up volume enables signicant 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” ow, 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 oers 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 CO₂ 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 specically 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 conguration.

The models are characterized by dierent 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.
