3003 / 3103 Internally Enhanced Round Tube / Aluminum Inner Grooved Tube
The Aluminum Inner Grooved Tube is following a helical pattern and have been optimized to improve heat transfer. The improvement in heat transfer coefficient of the tube is two times what can be achieved with
traditional smooth bore tubes3. This increased efficiency can help achieve a more compact design of the heat exchangers and a reduction in refrigerant load. different grooves depth and geometry satisfy the specific regional requirements and refrigerants in use.
