E6THx14/1P-SC-S 4x-(0)

E6THx14/1P-SC-S 4x-(0) designates a SWEP E6T brazed plate heat exchanger with 14 plates in the pack. 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. It is catalogued with 4x-(0) connections. The E6T plate pack measures 210 x 73 mm (8.27 x 2.87 in) on 172 x 40 mm port centres, and by SWEP's published weight formula a 14-plate unit comes to about 0.9 kg (2.1 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. If the flow on either side would excede the published ceiling, the answer is a larger frame, not more plates on this one.
