MicroGroove Faces Off Against Aluminum in OEM Product Development
2018/02/08
Copper Proves Its Superiority as a Heat Exchanger Material
 
New York, New York (15 January 2018) -- According to the International Copper Association, Inc. (ICA), MicroGroove consistently has been proven to be better than MicroChannel in many respects.
 
For many decades aluminum wanted to position itself as a possible substitute for copper in heat exchangers for air-conditioning applications. In the 1970s, round-tube, plate-fin (RTPF) coils made from aluminum tubes and aluminum fins rapidly corroded and deteriorated and equipment failures were widespread.  All-aluminum RTPF coils did not last long in real world environments and OEMs quickly reverted back to copper.
 
It would be several decades later before aluminum advocates would try again. Aluminum resurfaced in the form of extruded “multichannel” or “MicroChannel” tubes. OEMs began to experiment with aluminum multichannel coils, which were marketed as an alternative to copper. The suggested advantages of the smaller channels, i.e., high thermal heat transfer coefficients and reduced refrigerant volume, were heavily advertised.
