The new generation of Multi-Chamber Tubes is a kind of high precision extruded aluminum tube, also called “Multi-Port Extrusion Tube” (MPE Tube). MPE Tubes are flat tubes with multiple small channels along the tube length, i.e. they could be described as one large tube split into multiple smaller parallel ports. The flat geometry of MPE Tubes results leading in larger heat transfer rates on the Compact Heat Exchangers equipment, especially in – Air Conditioning Systems, Parallel Flow Condensers, Evaporators, etc.
