Audited Supplier (1)Features
Heat exchangers of the WEL2000 range
(shown above: WEL2001/A040) are
used to cool process/barrier fluids in
seal supply circuits. The heat exchangers
are made of helical, laser-welded finned
tubes. The cooling medium is ambient
air. It is important, therefore, for WEL
heat exchangers to be installed in well
ventilated places indoors or, ideally,
outdoors. There is a choice of three
different basic versions of the WEL2000
range, supplied fully assembled along
with valves, base frame and other system
components.
Circulation in accordance with API 682/
ISO 21 049: Plan 21, Plan 22, Plan 23,
Plan 41
(2)Advantages
• Helical finned tube design with vertical arrangement of the fins to the wind direction: the solution for high cooling capacities
• Welded finned tubes without gaps for guaranteed optimum energy transmission
• Universal usage: high-quality 1.4571 stainless steel finned tube design
• No cooling water connection or heating required for the cooling water pipe in winter
• There is a choice of three different basic version
(3)Standards and approvals
• PED 97/23 EC (Design and production in accordance with EU Pressure Equipment Directive)
• ASME VIII, Div. 1 (Calculation)
(4)Recommended applications
• Chemical industry
• Petrochemical industry
• Oil and gas industry
• Refining technology
• Power plant technology
(5)Notes
WEL heat exchangers should be installed in well ventilated places indoors or,
ideally, outdoors. Vertical installation is essential.
