Data Sheet
Micro Plate Heat Exchanger
Type C39L-EZ
A new compact and high-ecient evaporator
The C39L-EZ is an evaporator designed for use
in high-eciency mini chillers with capacities
up to 40kW, optimized for R410A and R32
respectively.
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 plate
pattern of the previous generation of MPHE,
C39L-EZ reduces the water side pressure drop
and the amount of material used. C39L-EZ also
has outstanding performance working as
condenser.
To meet demands for higher seasonal
eciency, the C39L-EZ is designed to work
eciently and increase comfort in modern life
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.

Micro Plate Heat Exchanger, type C39L-EZ
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 and reduced CO2 footprint
• Smaller footprint - enables more compact chillers for easy installation
• Less material utilization – less weight and environment friendly
