E5THx14/1P-SC-S 4x-(0)

This is the 14-plate E5T: SWEP designation E5THx14/1P-SC-S 4x-(0). Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 4x-(0). 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. Where a nameplate is worn, the plate count and the connection sizes are usually enough to separate this build from its neighbours in the series.
