• Straight-tube or U-tube designs
• 100% vibrational and acoustic resonance analysis
• All multi-pass exchangers, straight-tube or U-tube, include accurate counter-current and co-current flow analysis
• The U-bend area of U-tube exchangers is not included in the heat transfer calculations or effective area
• Precise expansion and contraction calculations are performed on all straight-tube exchangers to determine expansion joint necessity. (Expansion joints are not needed for U-tube designs)
• Reynolds Numbers are reported with each design to report the efficiency of the design
• Carefully calculated baffle-spacing, baffle-number, baffle-cut and baffle inlet/outlet locations
• Precise tubeside and shellside pressure drop calculations are reported with every design (Based on your allowable pressure drop)
• Precise tubeside and shellside velocity calculations are reported with every design (Utilizing industry accepted minimum values)
• TEMA recommended fouling factors used in every design
• Excess surface area is added to every design
  • Ensures exchanger will operate as efficiently tomorrow as it does today
• In the rare event of a ruptured tube, ABC can use a sanitary plug to seal-off the tube

4-pass Sanitary Heat Exchanger		In-Process Fabrication of Sanitary Heat Exchanger

Prior to shipment, every heat exchanger undergoes rigorous testing and documentation procedures that may include:

• Hydrostatic pressure testing
• Dye penetration examination
• X-ray analysis
• Saline testing
• Computer-verified performance
• Profilometer readings of surface finish to ensure mechanical and electropolished surface finishes
to less than 10 microinches Ra
• Fiber optic, borescopic tube inspection and videotaping of product contact surfaces
• ASME Code Stamping with National Board Registration
