Micro Plate Heat Exchanger
Type C118L-EZ and C118L-EZ-F
For more ecient Chillers
21% lower hold-up volume enables
signicant 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-eciency 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 coecient. 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
eciency, the C118L-EZ is designed to work
eciently and increase comfort in modern
buildings without increasing the carbon
footprint. Helping chillers perform more
eciently, it reduces both energy costs and
environmental impact. The low hold-up volume
reduces the system refrigerant charge and
oers valuable savings.
Features:
• Improved heat transfer - equals higher
eciency chillers
• Reduced water side pressure drop – equals
higher eciency 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 specically designed for high ecient 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 owconguration.
The models are characterized by dierent 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.
