E6THx20/1P-SC-S 4x3/4"(20)

E6THx20/1P-SC-S 4x3/4"(20) designates a SWEP E6T brazed plate heat exchanger with 20 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. 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. Connections are listed as 4x3/4"(20), in port order. 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 20-plate unit comes to about 1.2 kg (2.7 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Use this designation as the referance on a quote request; nothing more is needed until the duty itself changes.
