B15THx40/1P-SC-M 2x3/4"INT HEX+2x1/2"INT HEX

B15THx40/1P-SC-M 2x3/4"INT HEX+2x1/2"INT HEX designates a SWEP B15T brazed plate heat exchanger with 40 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 2x3/4"INT HEX+2x1/2"INT HEX. The B15T plate pack measures 468 x 76 mm (18.43 x 2.99 in) on 432 x 40 mm port centres, and by SWEP's published weight formula a 40-plate unit comes to about 5.4 kg (11.9 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Depth is the one dimension that changes across the plate counts of a series, so measure the space behind the unit before moving to a larger pack.
