The corporate structure of HE Tubing allows you to find quick and useful solutions. Alongside specific solutions, HE Tubing offers a number of standard extruded aluminum solutions:
Micro Port Extrusion
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.
Micro Port Extrusion for R744 / CO2
The introduction of new refrigerants for mobile air conditioning, in particular the change to CO2 (R-744) with its highly challenging technical operating conditions, asks for new aluminium solutions.
The condenser which is used in current air conditioning systems based on R-134a will be replaced by a CO2 (R-744) gas cooler. Multi Port Extruded aluminium for CO2 heat exchanger applications are developed to resist the high pressure of the CO2 system.
Aluminium heat exchanger round tubes at HE Tubing are directly extruded, coiled and delivered in “as extruded” temper.
Aluminium Round Tubing offers excellent corrosion resistance, high strength to weight ratio and adequate heat transfer properties. We offer internally enhanced (fins) and smooth walled round tubes to meet your unique requirements.
HE Tubing’s NEXCOR™ family of alloys provides documented material savings, especially when demanding forming processes are used.
- Superior mechanical properties in pre-brazed and post-brazed conditions
- Excellent corrosion behaviour compared to standard alloys
- Limited grain size growth after brazing due to finetuned alloy composition
