Multiport Extruded Aluminum Tube(MPE)- which is used for automobile air conditioner condenser has larger internal
section area, better effectiveness for heat transfer. At the same
time, has the following properties:
1. Lower energy costs
2. Higher performance
3. Less space and weight
4. High corrosion and pressure resistance
5. High recycling value
6. Pressure drop and silent solution
Beside increased global performances, an all-aluminium brazed heat
exchanger using MPE will also present better corrosion resistance.
MPEs are primarily used for the following applications:
Condensers
Evaporators
Oil coolers
Radiators
Heater cores
Multiport Extruded Aluminum Tube are available in various sizes and alloys, ensuring the best
properties for the purpose required.
Dimensions: Designed to customer specification
Package: coils or Straight with fixed length
Surface Treatment : Zinc spray / without Zinc spray
