WED
Features
Heat exchangers of the WED range are used to cool process/barrier fluids in seal supply circuits. Designed as a tubular heat exchanger with integrated guide plates, the process/barrier medium is directed through the shell of the WED and the cooling medium through the tubes.
Circulation based on API 682 / ISO 21 049: Plan 21, Plan 22, Plan 23, Plan 41
Advantages
- Tubular heat exchanger design with integrated guide plates, extremely efficient cooling capacity yet very compact dimensions
- Cooling capacity up to 36 kW*
- Universal usage: parts in contact with the medium are made of 1.4571
- It can be installed either in vertical or horizontal position
- The heat exchanger can be dismantled: easy to clean
Standards and approvals
- PED 2014/68/EU (Design and production in accordance with EU Pressure EquipmentDirective)
- ASME VIII, Div. 1 (Design, calculation and production)
Recommended applications
- Chemical industry
- Petrochemical industry
- Oil and gas industry
- Refining technology
- Power plant technology
Notes
Cleaning:
Cooling water side: it can be cleaned mechanically after the cover is removed.
Process/barrier medium side: flush with a suitable solvent.

²) Low Flow: 8 l/min (process fluid), 10 l/min (cooling water), ΔT = 40 K (hot–cold)
³) High Flow: 15 l/min (process fluid), 20 l/min (cooling water), ΔT = 40 K (hot–cold)
The cooling performance depends on the available fluids, their temperatures and flow rates. Please contact EagleBurgmann for professionally selecting the correct heat exchanger.
