Seal Supply Systems


Heat exchangers of the HE range are used to cool process/barrier fluids in seal supply circuits. HE 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, the heat exchanger can also be supplied with ventilation/drainage ball valves. In addition, the heat exchangers can also 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 21 049: Plan 21, Plan 22, Plan 23, Plan 41
