Brazed plate heat exchangers (BHE) consist of pressed stainless steel plates which are brazed with copper in a vacuum. For brazing, every alternate plate is rotated by one hundred and eighty degrees to produce two separate flow paths in which the two media flow in opposite directions. The plate contours generate high turbulence during fluid flow, which promotes efficient heat exchange even at low flow rates.
