GC & GL Conventional Plates

The corrugated plates have a gasket along the periphery. There are also gaskets around two of the four ports, which means that only one of the two fluids has access to the heating surface. The next plate has gaskets around the other two ports. Thus a channel system is created where two fluids pass every other channel respectively. Leakage between the two fluids is not possible due to double gaskets around the ports.

The pressure drop and heat transfer are dependent on factors such as the arrow angle of the plate pattern. An obtuse arrow angle (high-theta plate) means high resistance and a large thermal driving force. An acute angle (low-theta plate) means a low pressure drop but a smaller thermal driving force.
