B85Hx24/1P-SC-M 4x1"&22U(20)

This is the 24-plate B85: SWEP designation B85Hx24/1P-SC-M 4x1"&22U(20). 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. Connections are listed as 4x1"&22U(20), in port order. The B85 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 24-plate unit comes to about 5.4 kg (11.8 lb) dry. The frame is published to 17 m3/h (74.85 GPM) - a port limit rather than a design flow. Depth is the one dimension that changes accross the plate counts of a series, so measure the space behind the unit before moving to a larger pack.
