Data Sheet

Micro Plate Heat Exchanger
Type C12L-EZ

For more ecient Cooling & Heating systems

40% heat transfer increase compared to
traditional shbone design.

The C12L-EZ is an economizer optimized for
R410A for use in VRF, heat pump and bus A/C
etc., and also can be used as evaporator for
chiller with a capacity under 5.5KW. Inspired by
sh scales, 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 by 40%
compared with traditional shbone design at
the same evaporating temperature. At the
same time, inheriting from the dimple features,
C12L-EZ reducesthe amount of material used.
To meet demands for higher seasonal

eciency, the C12L-EZ is designed to work
eciently and increase comfort in modern

buildings without increasing the carbon
footprint. Helping A/C units 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

• Minimal hold-up volume - equals less
refrigerant charge

• Smaller footprint - enables more compact size

• High heat transfer and minimal refrigerant
charge - equals a reduced CO2 footprint
