The Micro Port Extrusion (MPE) is an extruded rectangular flat tube with multiple small channels running the length of the tube. The size range HE Tubing Netherlands is capable to extrude (and calibrate) is broad:

  • Width: 6 – 40 mm
  • Height: 1- 5 mm
  • Wall Thickness: 0,1 – 0,6 mm

MPE’s are exceptionally capable of handling high pressure refrigerants and are manufactured to meet the customer’s specific requirements with respect to alloy, geometry, wall and web thicknesses. The geometric characteristics of MPE’s are achieved by extrusion. The typical walls of MPE’s are thin, which makes the choice of alloy critical with regards to corrosion resistance.
Additional corrosion protection can be provided to the tube through the use of one of the coating solutions from HE Tubing.
Main application of the MPE’s is the paralell flow heat exchanger such as condensers and evaporators.
