Kelvion LWC Series Gasketed Plate Heat Exchangers
Handle Aggressive Media with Ease
The Laser Welded Cassette is for applications with aggressive media that might exceed the limits
of gasket seals. Well-suited for ammonia applications in:
Ideal for Ammonia-based Systems
Plates are laser-welded in pairs, eliminating the gaskets between them, allowing the use of ammonia and other agressive media that would normally exceed the limits of standard gasketed plate heat exchangers.The greater efficiency of the LWC means a smaller ammonia charge, reducing cost and maintenance.
Versatility
The right design, not a ”good enough” design. A variety of sizes and plate configurations combine with sophisticated selection software to ensure a perfect customization for your needs. The compact footprint allows you to use it in locations that you wouldn’t dream of with a shell-and-tube heat exchanger.
Now Even More Versatile! We now offer oxygen-free welding, which adds corrosion resistance AND makes it possible to supply such diverse plate materials as C-276, SMO 254, Alloy 686 and numerous others. Contact us for the full list.
Higher Performance at a Lower Cost
Optiwave™ plate corrugations distribute the media evenly across the entire plate width, maximizing heat transfer and minimizing the number of plates (and cost) required.
Peace of Mind
Over 75 years of experience in designing and crafting high performance plate heat exchangers. Independent performance certification through ASME and other programs.
Convenient Maintenance
PosLoc™ plate lead-ins cause the plate pack to self-align when re-installing during maintenance. Ecoloc™ tools-free gaskets make gasket replacement a snap. Individual plates mean no heavy lifting tools. The result is faster, more efficient maintenance, with shorter down times.
