Micro Plate Heat Exchanger
For more efficient system

H34-CL & CM Suction Gas to Liquid Heat exchanger

H34-CL/CM is Microplate Heat Exchanger
optimized for applications in Heat pump systems
specifically for the heat transfer process in
between the suction gas and the liquid line.

Specifically design to operate with refrigerants
characterized by large glide like R454C or R455A,
applied as suction gas heat exchanger it
contributes to keep low the temperature
approach in condensation and evaporation
phase helping to achieve high efficiency for the
heat pump system.

The model is available in two versions covering
capacity systems up to 70 kW:

• CL for low pressure drop

• CM for high heat transfer coefficient

Thanks to the technology flexibility of the
microplate concept, it can be applicable also as
condenser and or desuperheater for capacity up
to 30 kW.

Features • Minimal hold up volume: Less refrigerant

charge

• High heat transfer: For a more efficient system
where heat exchanger is implemented

• Reduced CO₂ footprint: Environmentally
friendly with high heat transfer and minimal
refrigerant charge

• Small footprint enables more compact heat
pumps

40%

charge compared with a traditional BPHE.
The ideal solution to meet the world`s climate
and energy spirations.
