WDK
Features
WDK5120 heat exchangers are used to cool process/barrier fluids in seal supply circuits. The heat exchanger has a wound double helix around the guide tube. Process/barrier medium in the tubes, cooling medium around the tubes.
Circulation based on API 682 / ISO 21049: Plan 21, Plan 22, Plan 23, Plan 41
Advantages
- Effective cooling: with wound double helix around a guide tube
- Cooling capacity up to 10.5 kW
- Excellent value for money
- Vessel can be dismantled: for optimum cleaning of the cooling water side
- Universal usage: parts in contact with the buffer medium are made of 1.4571
Standards and approvals
- PED 2014/68/EU, Art. 4, Paragraph 3 (Design and production in accordance with EU Pressure Equipment Directive, without CE-Sign)
Recommended applications
- Chemical industry
- Petrochemical industry
- Power plant technology
- Refining technology
- Oil and gas industry
Notes
Mount vertically with connections pointing up. Provide for external venting on the process/barrier medium side (the user has to install a vent at the highest point of the pipe work).
Cleaning:
Cooling water side: the area around the tubes can be cleaned mechanically after the housing is removed.
Buffer 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.
