Refined Heat Exchanger Design
Mistral range features the new heat exchangers with reduced internal volume, high-performance aluminium fins, and inner grooved copper tubes which facilitate a more efficient heat transfer due to the 65% larger inner surface area. The groove’s torsion promotes turbulent flow, resulting in improved inside-the-tube heat transfer characteristics.
Copper tubes manufactured using the new pressure expansion method show significant improvements over traditional mechanical expansion methods and feature better tube-fin contact, higher strength for resisting internal pressure, and improved overall heat transfer performance for a coil.
Available heat exchanger treatments include pre-painted fins, hydrophilic and hydrophobic coatings, and electrophoretic epoxy paint.
