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