Tubes and heat exchangers for CO₂ applications

: Aluminium heat exchanger; Aluminium heat exchanger

Wieland finned tubes provide a significantly increased heat transfer surface resulting in a higher heat transfer coefficient as a function of design and application.

Wieland finned tubes are available in various shapes and can be used in heat exchangers such as internal heat exchangers IHX and connection lines.

Basic specifications

Materials: aluminium, copper, copper alloys (e.g. Wieland K65)
Dimensions: customized from <10mm to >50mm fin diameter, according to the needs of the application
Surface cleanliness: on request suitable for refrigerant applications
Available in straight lengths
(on request: heat exchanger shape ready for installation)

Benefits

Increased heat transfer surface - more than three times larger than that of plain tubes - for compact designs and smaller volumes
Higher heat transfer coefficient depending on design and application
Pressure-resistant for high-pressure applications
Available with different fin structures and fin shapes for optimized performance
Bendable to very tight radii for compact designs
