SUPERMAX® Shell And Plate Heat Exchanger

The SUPERMAX® Shell And Plate Heat Exchanger is designed as a performance upgrade over shell and tube, block-type welded and brazed aluminum heat exchangers. The unit can overcome footprint constraints, extreme pressures/temperatures, fouling/scaling conditions and corrosive attack with liquids, gases, steam and two-phase mixtures.

REDUCED FOOTPRINT

Compact size and low installed weight, especially when filled

WIDE TEMPERATURE/PRESSURE RATINGS

Good performance with natural refrigerants such as ammonia and carbon dioxide

EXCELLENT THERMAL PERFORMANCE

Close temperature approach of 1ºC (2°F) –similar to that of gasketed plate heat exchangers

OUTSTANDING UPTIME

Highly turbulent flow produces high heat transfer efficiency and limits fouling, or freezing in refrigeration/cryogenic service

SMALL HOLD-UP VOLUME

Fast start-ups and close following of process changes; low refrigerant charges for refrigeration and cryogenic service

TWO-PHASE FLUID FLEXIBILITY

Extended-thermal-length oblong plates expand capabilities to wide-ranging evaporation and condensing applications

RELATED SHELL AND PLATE APPLICATIONS

  • Particulate-laden flows: Turbulent flow, even at low velocities, enables stable capacity regulation and minimizes fouling
  • Refrigeration and cryogenic service: the exchangers require a low refrigerant charge; are also resistant to freezing because of high fluid turbulence
  • Internal phase changes: on either the plate or shell side
  • Large flow imbalance: Allow higher flow rates on the shell side
  • Installation factors: Can be installed horizontally or vertically

RELATED SHELL AND PLATE SERVICES

  • Standard and deep-draw plates enable accommodation of flow rate and pressure drop constraints. Oblong plates enable configuration to attain necessary thermal length
  • Removable Core exchanger provides full accessibility to the thermal element for inspection and/or mechanical cleaning of the shell side channel by removing the plate pack bundle
  • The Multi-Duty exchanger has two separate plate packs that share one shell, handling different or identical fluids
  • Multi-Pass configurations for gas or vapor cooling without condensing
  • Co-current or counter-current plate groupings

HOW THE SUPERMAX SHELL AND PLATE HEAT EXCHANGER WORKS

  • The shell and plate welded heat exchanger has a heat transfer element composed of round or oblong chevron-type plates welded into a cassette by a porthole perimeter weld
  • Cassettes are placed together and welded to each other using a perimeter weld
  • The thermal element subassembly then has metal shell-side flow diverters, nozzles and an end plate welded to it
  • An exclusive cage structure, welded only to the end cover, surrounds and supports the plate core pack assembly
  • The finished exchanger is a pressure vessel of high integrity, with an accordion-like core that is highly tolerant of thermal expansion
