B25THx60/1P-SC-S 2x1 1/4"INT HEX+2x1"INT HEX

B25THx60/1P-SC-S 2x1 1/4"INT HEX+2x1"INT HEX designates a SWEP B25T brazed plate heat exchanger with 60 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. The connection field reads 2x1 1/4"INT HEX+2x1"INT HEX. The B25T plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 479 x 72 mm port centres, and by SWEP's published weight formula a 60-plate unit comes to about 12.8 kg (28.2 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. If the flow on either side would exceed the published ceiling, the answer is a larger frame, not more plates on this one.
