DRY COOLERS

Mistral dry coolers

Expertly engineered, reliable and efficient dry coolers for refrigeration, air conditioning, and process applications in the cooling capacity range up to 1MW

10-1000kW

PRODUCT OVERVIEW

Reliable solution for industrial and commercial applications

This comprehensive range of dry coolers, which includes more than 600 models in horizontal design with the capacity range from 10 to 1000 kilowatts, has been engineered for maximum efficiency and flexibility. The machines offer easy installation, low maintenance costs, and long service life.

Mistral dry coolers characterized by low sound emission fans, enhanced finned tube heat exchangers with an increased tube wall thickness and thicker fins, and a huge choice of options and accessories for tailor made solutions.

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.

 

Low sound emission level allows installation in populated urban areas and everywhere where low noise pollution is an essential factor.

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 improved overall heat transfer performance for a coil.
