High heating transferring coefficient: as the flowing made in the plate pack forms up turbulence at low Re and the smooth plates have little possibility of forming scale, the plate heat exchanger has a heat transferring coefficient over 5000W/m2k, which is 2-4 times that of the shell-and-tube exchanger.
High heat recovery rate: Thanks to the high heat-transferring coefficient, the heat transferring temperature difference can be very low Therefore, it is very well suited to low energy level heat recovery. Normally heat recovery using a plate heat exchanger can be as high as9 0%.
