B5THx18/1P-SC-M 2x16+2x28U

This is the 18-plate B5T: SWEP designation B5THx18/1P-SC-M 2x16+2x28U. 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. Connections are listed as 2x16+2x28U, in port order. The B5T plate pack measures 193 x 76 mm (7.6 x 2.99 in) on 154 x 40 mm port centres, and by SWEP's published weight formula a 18-plate unit comes to about 1.4 kg (3.0 lb) dry. Maximum flow for the frame is 4 m3/h (17.61 GPM); that is a ceiling for the ports, not a duty point. A like-for-like order needs only this string; we recommend adding the fluids and flows where the system has been altered.
