Enhanced Heat Exchangers
Mistral dry coolers feature upgraded heat exchangers with reduced internal volume, aluminium fins with 25% increased thickness, and inner grooved copper tubes, which facilitate more efficient heat transfer through an inner surface area increased in size by 65%. The groove’s torsion promotes turbulent flow, resulting in improved tubeside heat transfer characteristics.
Copper tubes manufactured using the new pressure expansion method show significant improvements over traditional mechanical expansion methods and feature improved tube-fin contact, higher strength for resisting internal pressure, and enhanced overall heat transfer performance for a coil.
Available heat exchanger treatments include pre-painted fins, hydrophilic and hydrophobic coatings, and electrophoretic epoxy paint.
Quiet and Efficient Axial Fans
Mistral dry coolers have fans with alternating current (AC) motors as a standard, and fans with electronically commutated (EC) motors as an option; fan diffusers and selection of three sound level grades giving customers the choice of a bespoke solution that suits their requirements.
Mistral dry coolers can be supplied in three noise intensity designs: standard, low-noise, and ultra-low noise levels. Low sound emission level allows installation in populated urban areas and everywhere where low noise pollution is an essential factor.
