B85Hx140/1P-SC-M 4x1 1/2"

This is the 140-plate B85: SWEP designation B85Hx140/1P-SC-M 4x1 1/2". 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 1/2", 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 140-plate unit comes to about 21.2 kg (46.8 lb) dry. Maximum flow for the frame is 17 m3/h (74.85 GPM); that is a ceiling for the ports, not a duty point. Use this designation as the reference on a quote request; nothing more is needed until the duty itself changes.
