B16DWHx60/1P-SC-M 4x1 1/4"&28U

The B16DWHx60/1P-SC-M 4x1 1/4"&28U is a 60-plate build of the SWEP B16DW. 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. Connections are listed as 4x1 1/4"&28U, in port order. The B16DW plate pack measures 377 x 119.5 mm (14.84 x 4.70 in) on 329 x 72 mm port centres, and by SWEP's published weight formula a 60-plate unit comes to about 14.8 kg (32.5 lb) dry. The frame is published to 11 m3/h (48.40 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.
