Heat Exchanger Design Software ( Thermal Design )


• Interactive input, calculations, and review of results.
• Help screens
• Flexible engineering units
• Extensive data checking
• Customized reports
• Graphical plotting of results
• Integration with CHEMCAD and CHEMCAD thermodynamics


• DESIGN AND Rating modes
• Calculation of all TEMA types:
o Sensible flow (vapor or liquid)
o Forced evaporation
o Falling film evaporation
o Vertical thermosyphon
o Horizontal condensation
o Vertical condensation
o Reflux condensation
• Shellside process types:
o Sensible flow (vapor or liquid)
o Forced evaporation
o Pool evaporation
o Horizontal thermosyphon
o Horizontal condensation
o Vertical condensation
• Exchangers may have evaporation on one side with condensation on the other with any combination of subcooling and superheating
• A full stream analysis is performed on the shellside
• Zone-by-zone analysis is performed (2-31 zones, user defined)
• The conditions and properties are automatically generated at all zones and can be modified by the user.
• A complete library of materials is incorporated for tubes, pipes, shells, bonnet, and tubesheets.
• Dry wall or wet wall condensing
• Thermosyphon simulation mode


• Shells in series or parallel
• Shell as pipe or plate
• Sealing strips permitted
• Diameter or maximum diameter may be specified


• Tubes may be bare or fin
• Turbulators may be used on the inside of the tube
• User may specify tube OD, gauge, pattern, and pitch
• Tubesheet thickness calculated to determine effective area
• U-bend radius and/or efficiency may be specified
• Tube length or maximum tube length may be specified


• Baffles may be single segmental, double segmental, tiple segmental, full circule, no-tubes-in-window, or rod baffles
• User may specify or have the program optimize the baffle spacing, cut, and direction
• Impingement baffles are accommodated


• Safety factors may be specified
• Entrainment ratios
• Kettle diameter
• Shellside or tubeside coefficient may be fixed
• Tube axial stress
• Vibration analysis
• Zone by zone analysis of heat transfer and pressure drops calculations
