B28Hx46/1P-SC-S 4x1 1/4"(D24.70)

Part number B28Hx46/1P-SC-S 4x1 1/4"(D24.70) is the SWEP B28 frame carrying 46 plates. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. 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 4x1 1/4"(D24.70), in port order. The B28 plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 470 x 63 mm port centres, and by SWEP's published weight formula a 46-plate unit comes to about 9.6 kg (21.2 lb) dry. Maximum flow for the frame is 16.9 m3/h (74.41 GPM); that is a ceiling for the ports, not a duty point. A like-for-like order needs only this string; we reccomend adding the fluids and flows where the system has been altered.
