B120THx70/1P-SC-M 2x42U+2x1 1/2"&35.1

The B120THx70/1P-SC-M 2x42U+2x1 1/2"&35.1 is a 70-plate build of the SWEP B120T. 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. The connection field reads 2x42U+2x1 1/2"&35.1. The B120T plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 456 x 174 mm port centres, and by SWEP's published weight formula a 70-plate unit comes to about 36.6 kg (80.7 lb) dry. The frame is published to 27.4 m3/h (120.64 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.
