The solution consists of an internally enhanced aluminium tube for high-fin density condensers and evaporators. The inner grooves improve heat transfer, offering higher efficiency by more compact design.
Additional zinc coating layers are available to further increase corrosion resistance, which makes this product a high-performing tube. Different depths and geometries of the grooves satisfy the specific regional requirements and refrigerants in use.
The inner grooves follow a helical pattern and have been optimized to improve heat transfer. The improvement in the heat transfer coefficient of the tube is two times what can be reached with traditional smooth-bore tubes. This increased efficiency can help achieve a more compact design of the heat exchangers and a reduction in refrigerant load.
Different depths and geometries of the grooves satisfy the specific regional requirements and refrigerants in use.
For heat exchangers operating in aggressive environments, our experts strongly recommend the addition of a zinc coating to the tubes. This additional layer provides the tubes with increased corrosion protection and prolonged lifetime compared to the equivalent bare tube.
This zinc coating is available on smooth-bore tubes, and straight inner-grooved tubes.
