During the brazing process the plates are packed by turning them by 180° so to produce two separate flow chambers, where the fluids, which have to exchange heat, flow in opposite directions.

The pressure on the plates causes a great turbulence in the fluids; this increases the thermic exchange coefficients even in case of little volumetric flows.

Advantages of this solution are a compact and light unit, a high thermic exchange coefficient thanks to the particular structure of the plates, a high working temperature and pressure, a high corrosion resistance because the plates are in stainless steel and a simple installation and reparation: no maintenance is required.
