Products Details

The inner grooved aluminum pipes are available in various 3xxx alloys like 3003,3103. To achieve optimum performance of the tubes it is important to use the correct publication in the expansion process.

The thermal-hydraulic performance of typical OD 7.0mm tubes was tested with R410A, the dominant refrigerant in air conditioning and heat pump applications.  A popular copper micro-fin tube for the standard all-around purpose was also tested to demonstrate that the performance of inner grooved aluminum pipes has similar performance.
