Data Sheet

Micro Plate Heat Exchanger Type C55(L)-EU

For more ecient Chillers

30% lower hold-up volume, signicant reduction in refrigerant and smaller CO

footprint, compared with a traditional BPHE

The C55L-E is an evaporator optimized for R410A for use in high-eciency chillers with capacities of 10-65 kW. The heat exchanger features innovative Micro Plate technology that improves heat transfer and reduces the amount of material used.

To meet demands for higher seasonal

eciency, the C55L-E is designed to work eciently and increase comfort in modern

buildings 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.

Thanks to the mixing chamber, the innovative refrigerant distribution device, the C55(L)-EU is applicable with all refrigerant types.

Features:

• Minimal refrigerant hold-up volume: Smaller refrigerant charge

• High heat transfer: For a more ecient chiller

• Minimal pressure losses on secondary side: Less pump power

• Smaller footprint: Enabling more compact chiller

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

refrigerant charge
