Micro Plate Heat Exchanger

Type C39L-EZ

A new compact and high-ecient evaporator

The C39L-EZ is an evaporator designed for use
in high-eciency 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 coecient. 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

eciency, the C39L-EZ is designed to work
eciently and increase comfort in modern life

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.
