WED5

Features

Heat exchangers of the WED5 range (photo: WED5050/A020-D1) are used to cool process/barrier fluids in seal supply circuits. WED5 heat exchangers are available in 3 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 of the cooling water side, the heat exchanger can also be supplied with drainage ball valves. In addition, the heat exchangers can also be combined with a temperature instrument in the supply line to mechanical seal (optional in accordance with API 682).
Circulation in accordance with API 682 / ISO 21049: Plan 21, Plan 22, Plan 23, Plan 41
