Thermal length - plates channels

• These form three different channels (L, M and H)

High turbulence pressure drop best U Value
and highest wall shear
Medium turbulence pressure drop - better U
value and higher wall shear
Low turbulence pressure drop, good U value
and wall shear
L L L channels
L H M channels
H H H channels

Minimising Fouling Through Design

• Consider the fluids physical properties, size,
  quantity and characteristics of particles
• Number size of plates are determined by flow
  rate, physical properties, pressure drop
  temperature program

High shear and turbulent flow help minimize
fouling
8
Gasket - Profile and Gasket Groove
Alfa Laval
Profile
Higher sealing pressure
Groove
Full support to gasket
The difference is life time and reliability
