B10THx26/1P-SC-M 4x1"&22U

B10THx26/1P-SC-M 4x1"&22U designates a SWEP B10T brazed plate heat exchanger with 26 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. The connection field reads 4x1"&22U. The B10T plate pack measures 289 x 119 mm (11.38 x 4.69 in) on 243 x 72 mm port centres, and by SWEP's published weight formula a 26-plate unit comes to about 3.6 kg (8.0 lb) dry. Maximum flow for the frame is 9 m3/h (39.63 GPM); that is a ceiling for the ports, not a duty point. If the flow on either side would exceed the published ceiling, the answer is a larger frame, not more plates on this one.
