Nice numbers, AC and Mike

Over at the Polish builders forum someone posted this:




Apparently, it is a PP coroplast HX, produced by Canadian Greentek, which claims its efficiency matches that of other (metal) crossflow heat exchangers.
From the images above it appears that the HX is not made of squares of coroplast rotated 90°, but instead the squares have spacers between them. This has two advantages: lower pumping losses (on one side) and single walls (instead of double) between airflow streams. Could you guys try a test with spacers?
