Plate-fin heat exchangers – Design variants
Linde Engineering’s plate-fin heat exchangers (PFHEs) come in a number of different design variants, providing the perfect solution for a wide range of requirements.
Plate-fin heat exchangers play a key role in many different industries. We offer a range of different designs for various cryogenic applications.
Single blocks
A single PFHE- blocks comprises the Brazed core, Stub ends and Flanges.
Benefits:
Very compact design
Low weight
Small possible temperature differences
Highly efficient heat transfer
Low pressure drops
Piped PFHE systems
A piped PFHE system comprises several exchanger blocks that are assembled and installed in a transport frame with support beams. Each battery of blocks is insulated on site.
Benefits:
Handling of large flowrates
Optimised configuration for proper flow distribution
Flanged terminations for time effective installation at site
Coldboxes
A coldbox covers several exchangers, vessels, piping, instrumentation and valves installed in a carbon steel compartment.
Benefits:
Cost-effective solution
Perlite filling (insulation)
Supplied as a turnkey packaged unit
Time effective installation at site
Block-in-shell
A block-in-shell comprises one or more heat exchanger blocks installed in a shell instead of a tube bundle. This is a highly efficient and cost-effective alternative to standard shell-and-tube heat exchangers.
Benefits:
Tighter approach temperatures
Smaller size and weight
Lower installation costs
Reduced operating costs due to lower energy consumption
