PLATE HEAT EXCHANGERS 
(PHE)








Heat Exchanger Designs:

  • Paraflow Plate Heat Exchangers: The APV Paraflow is the original plate type heat exchanger designed by SPX to provide maximum efficiency and cost effectiveness in handling a wide variety of heat transfer applications. Units come in different configurations, as follows:                 
    • Single Wall Gasketed (Paraflow) Plate Heat Exchangers - The traditional plate and frame heat exchanger
    • Double  Wall (Duo-Safety) Plate Heat Exchangers - Used to prevent cross contamination of the fluids
    • Semi-Welded (Paraweld) Plate Pair Plate Heat Exchangers - No gaskets on one plate channel, gasket on the other side for the ultimate in flexibility and safety
  • ParaBrazed Plate Heat Exchangers: ParaBrazed heat exchangers are a compact, cost effective unit designed to deliver high thermal efficiency while maintaining lower pressure drops. It’s the perfect choice for many single and two phase heat transfer applications for industrial and refrigeration duties.
  • Hybrid Heat Exchanger - All Welded Design: All welded Hybrid heat exchangers combines the advantages of a plate and frame heat exchanger with those of a tubular exchanger. The APV Hybrid heat exchanger has a very flexible design for a wide range of temperatures and pressures.
  • Plate Type Evaporator
  • Scrape  Surface heat Exchangers

 



Advantages of Gasketed Plate V/s Tubular Heat Exchangers:

 

High Heat Transfer

  • Film coefficients three to five-times greater
  • Efficient operation with up to 98% heat recovery or regeneration
  • Low liquid hold-up enables faster reaction times to change in process
  • Fluids flow counter-current to each other between the parallel passages in each pass         

Economical and Compact

  • Reduces floor space by up to 90%, weighs less and delivers higher performance
  • Lower hold-up volume minimizes the amount of product required for flooding, reduces usage of high cost service fluids and improves thermal reaction times
  • Reduced capital costs and installation expenses
  • High energy recovery reduces energy costs         

Cleanability

  • Efficient design of heat transfer area reduces fouling caused by debris and dirt
  • Simplified cleaning and plate accessibility
  • Designed for use of effective CIP, removing chemical films or scaling deposits

Accessibility

  • Full access to both sides of the heat-transfer surface for inspection, maintenance, and cleaning
  • Access is readily accomplished within the installed space of the unit         

Flexibility

  • Modular design enables expansion of your heat exchanger as process requirements grow
  • Handles multiple duties and fluid streams in a single unit
  • Easily reconfigured to meet changing process needs
  • Wide variety of sizes and style ensuring optimal solutions for your applications
