Micro Plate Heat Exchanger

For more efficient system

HDW44-C Double wall Condenser

HDW44-C is double wall heat exchanger designed for application as condenser or desuperheater where the flow mediums are not allowed to mix.

The double wall heat exchanger prevents primary media to be mixed with the secondary media if there is an internal leak in the unit.

40%

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

Features	• Minimal hold up volume: Less refrigerant
	charge
	• High heat transfer: For a more efficient system
	where heat exchanger is implemented
	• Reduced CO footprint: Environmentally
	friendly with high heat transfer and minimal
	refrigerant charge
