The inner groove tube features a smooth outer surface and a grooved inner surface. This ensures a higher heat exchange efficiency than traditional copper coils. These tubes are primarily used in HVAC piping systems, air conditioners, air handling units, central air conditioners and freezers. Our inner grooved tubes undergo a strict eddy-current and performance test to ensure the quality customers have come to expect from us.
Main Features
1. High heat transfer efficiency
2. Easy to clean
3. Easy brazing and welding
4. High corrosion resistance
5. Various degrees of ductility
Why should I choose an inner grooved tube?
Inner grooved tubes are used to help improve the energy efficiency in a heat exchanger. With the increased surface area, the heat transfer coefficient is 2 to 3 times more compared to a traditional copper pipe in the same specifications. The heat transfer efficiency is also increased as the refrigerant is evenly distributed on the inner wall of the copper tube.
