COTS – COMPACT & MINIATURE HEAT EXCHANGERS

Commercial Off The Shelf

VPE’s compact & miniature heat exchangers are now offered in a wide selection of off-the-shelf models.  These heat exchangers are manufactured using the same technology as VPE’s Diffusion Bonded Microchannel Heat Exchangers (MCHEs), which are also known as Printed Circuit Heat Exchangers (PCHEs).  These high reliability, compact heat exchangers outperform and compete with the standard products such as Shell & Tube and Brazed or Welded Plate heat exchangers.

Benefits

  • Significantly more surface area
  • Higher heat transfer coefficient
  • Higher operating pressure capability
  • Higher temperature capability – only limited by material
  • Higher geometry factor – pure counter flow
  • Smaller footprint and weight
  • Diffusion bonded as opposed to brazed, providing high leak integrity and no braze alloy used
  • Lower fluid inventory
  • Exceptional mechanical performance in terms of handling transients, thermal stress, (suitable for larger temperature differences)
  • Readily customizable for multi-stream, ultra-high pressure, low MW gases, sCO2, etc.
  • Corrosion resistant alloys
  • Competitive pricing
  • Off-the-Shelf models or custom designed upon request
