Data Sheet

Micro Plate Heat Exchanger
Type H62L-EZU

For more ecient Heat Pumps

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

The H62L-EZU is an evaporator optimized for
R410A for use in high-eciency heat pumps
with capacities of 5-40 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 dimple plate pattern
of the previous generation of MPHE, H62L-EZU
reduces the water side pressure drop and the
amount of material used. In the reversible
mode of the heat pump as a condenser, H62L­EZU also has outstanding performance.

To meet demands for higher seasonal

eciency, the H62L-EZU is designed to work
eciently and increase comfort in modern

residential and commercial buildings without
increasing the carbon footprint. Helping heat
pumps 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.

Thanks to the mixing chamber, the innovative
refrigerant distribution device, the H62(L)-EZ is
applicable with all refrigerant types.

Micro plate heat exchanger, type H62L-EZU

Features

• Improved heat transfer - equals higher eciency heat pumps

• Reduced water side pressure drop – equals higher eciency heat pumps

• Minimal hold-up volume - equals less refrigerant charge

• Smaller footprint - enables more compact heat pumps

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

Portfolio overview

H62L-EZU: Evaporator optimized for R410A, R32, R452B and R454B
H62-EZU: Evaporator for low/medium density refrigerants PS: 30bar

Application

The H62(L)-EZU is single circuit evaporators specically designed for highly ecient heat pump systems. The
evaporator is design to operate also in reversable systems in condenser mode, in co or counter current ow

conguration.

Thanks to the mixing chamber, the innovative refrigerant distribution device, the H62(L)-EZ is applicable with all
refrigerants types.
