B12Hx60/1P-SC-S 2x1 1/4" INT HEX(27)+2x1"INT HEX(27)

B12Hx60/1P-SC-S 2x1 1/4" INT HEX(27)+2x1"INT HEX(27) designates a SWEP B12 brazed plate heat exchanger with 60 plates in the pack. 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 S is the pressure class: 31 bar at 155 C. Connections are listed as 2x1 1/4" INT HEX(27)+2x1"INT HEX(27), in port order. The B12 plate pack measures 287 x 117 mm (11.3 x 4.61 in) on 234 x 63 mm port centres, and by SWEP's published weight formula a 60-plate unit comes to about 7.0 kg (15.3 lb) dry. Maximum flow for the frame is 16.9 m3/h (74.41 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 untill the duty itself changes.
