B85Hx60/1P-SC-M 4x1 1/4"&28U(27)

This is the 60-plate B85: SWEP designation B85Hx60/1P-SC-M 4x1 1/4"&28U(27). 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. It is catalogued with 4x1 1/4"&28U(27) connections. 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 60-plate unit comes to about 10.3 kg (22.7 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. For a new duty, send the inlet temperature on each side and the flows, and we will say immediatly whether this plate count is the right one.
