B50Lx40/1P-SC-S 4x2 1/2"(54)

This is the 40-plate B50: SWEP designation B50Lx40/1P-SC-S 4x2 1/2"(54). The L plate is the acute chevron, which gives up some heat transfer per plate for a lower pressure drop - the usual answer when the available head is small. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 4x2 1/2"(54). The B50 plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 441 x 159 mm port centres. If the duty has changed since the original equiptment went in, send the flows and both inlet conditions and we will confirm whether this configuration still fits.
