E5THx14/1P-SC-S 4x3/4"(20)

This is the 14-plate E5T: SWEP designation E5THx14/1P-SC-S 4x3/4"(20). The H plate is the obtuse chevron: it gives the most heat transfer per plate and the most pressure drop, so it suits duties where approach temperature matters more than pump head. 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 4x3/4"(20). The E5T plate pack measures 192 x 73 mm (7.56 x 2.87 in) on 154 x 40 mm port centres, and by SWEP's published weight formula a 14-plate unit comes to about 0.9 kg (1.9 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Depth is the one dimension that changes accross the plate counts of a series, so measure the space behind the unit before moving to a larger pack.
