Applications:
The multi port extrusion (MPE),with their large internal surface
area, yield more efficient heat transfer and
are therefore ideal for use in highly effective heat exchangers.
Beside increased global performances, an all-aluminium brazed heat
exchanger using MPE will also present better corrosion resistance.
The multi port extrusions(MPE) are found mainly in applications
such as condensers and evaporators for air conditioning systems as
well as liquid lines for air conditioning, heater cores and
radiators for engine cooling systems, charge air coolers and other
cooling systems.
Dimensions:
The multi port extrusions(MPE) are available in various sizes and
alloys, ensuring the best properties for the purpose required.
| MPE | Width | 7-120mm |
| Height | 1-10mm |
| Wall thickness | 0.2-0.5mm |
| Other non-standard dimensions are available upon request. |
Package: In coil or Straight with fixed length.
Surface Treatment : With Zinc spraying or without Zinc spraying.
