E6THx12/1P-SC-S 4x-(0)

E6THx12/1P-SC-S 4x-(0) designates a SWEP E6T brazed plate heat exchanger with 12 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 12-plate unit comes to about 0.9 kg (1.9 lb) dry. Maximum flow for the frame is 4 m3/h (17.61 GPM); that is a ceiling for the ports, not a duty point. For a new duty, send the inlet temperature on each side and the flows, and we will say immediately whether this plate count is the right one.
