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
