B86Hx30/1P-SC-M 4x1"&22U(20)

This is the 30-plate B86: SWEP designation B86Hx30/1P-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. It is catalogued with 4x1"&22U(20) connections. The B86 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 30-plate unit comes to about 6.2 kg (13.6 lb) dry. Maximum flow for the frame is 9 m3/h (39.63 GPM); that is a ceiling for the ports, not a duty point. It is not necessary to send drawings for a like-for-like replacement - the string above carries the whole build.
