Heat exchangers of the WE6 range are used to cool process/barrier fluids in seal supply circuits. WE heat exchangers are available in two standard sizes and are API 682 conform. The process/barrier medium is directed through the tube and the cooling medium through the shell. For simple draining or venting of the cooling water side, he heat exchanger can also be supplied with ventilation/ drainage ball valves. In addition, the heat exchangers can lso be combined with a temperature instrument in the supply line to the mechanical seal (optional in accordance with API 682). Circulation in accordance with API 682 / ISO 21049: Plan 21, Plan 22, Plan 23, Plan 41
•Operating limits up to 45 bar / 260 °C (tube side): suitable for a wide range of demanding operating conditions. •Heat exchanger can be dismantled: for optimum and simple cleaning of the tubes
•Cooling water side and process side can be completely vented and drained
•1.4404 stainless steel: high resistance to corrosive fluids
Standards and Approvals
•PED 2014/68/EU (Design and production in accordance with EU Pressure Equipment Directive)
•ASME VIII, Div. 1 (Design, calculation and production)
Cooling water side: the area around the tubes can be cleaned mechanically after the housing is removed.
Process/barrier medium side: flush with a suitable solvent.
