B8LASHx20/1P-SC-M 4x3/4"&16

This is the 20-plate B8LAS: SWEP designation B8LASHx20/1P-SC-M 4x3/4"&16. 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. The connection field reads 4x3/4"&16. The B8LAS plate pack measures 317.7 x 76.2 mm (12.51 x 3.00 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 20-plate unit comes to about 2.0 kg (4.5 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Thermal performence depends on the duty as much as on the part number, so include the fluids if the unit is going into a new application.
