Micro Plate Heat Exchanger
Type C117L-EZD

For more ecient Chillers

21% lower hold-up volume enables
signicant reduction in refrigerant charge.

C117L-EZD is an evaporator optimized for
R410A for use in high-eciency chillers with
capacities of 50-200 kW, and standard
eciency chillers with capacities of 50-250 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 plate
pattern of the previous generation of MPHE,
C117L-EZD reduces the water side pressure
drop and the amount of material used. In the
reversible mode of the chiller as a condenser,
C117L-EZD also has outstanding performance

To meet demands for higher seasonal

eciency, the C117L-EZD is designed to work
eciently and increase comfort in modern

commercialbuildings without increasing the
carbon footprint. Helping chillers perform more
eciently, it reduces both energy costs and
environmentalimpact. 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

Table 1: Designation

Application

The C117L-EZD is true dual 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. All models can run with high eciency also in condenser mode.
