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
