B25THx40/1P-SC-S 2x1 1/4"INT HEX+2x1"INT HEX

This is the 40-plate B25T: SWEP designation B25THx40/1P-SC-S 2x1 1/4"INT HEX+2x1"INT HEX. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. 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. Connections are listed as 2x1 1/4"INT HEX+2x1"INT HEX, in port order. 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 40-plate unit comes to about 9.2 kg (20.3 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. Treat each side as an independant circuit when you ask for a quote: give both flows and what each fluid is.
