Product Introduction:
The Aluminium Microchannel Flat tubes,also called Aluminium Multi Port Extruded tubes,are unique tubes developed with highly refined manufacturing quality. With their large internal surface area, they can achieve more efficient heat transfer and hence are widely used in highly effective heat exchangers.
The Aluminium Microchannel Flat tubes,or Aluminium Multi Port Extruded tubes are unique tubes developed with the highest manufacturing quality and is characterized by the following properties:
1. Low energy costs
2. High performance
3. Low space and weight
4. High corrosion and pressure resistance
5. High recycling value
6. Pressure drop and silent solution
7. Low refrigerant fill
