Just a few of the standard features performed by our expert heat exchanger design team include:
- Straight-thru, U-tube or Coil 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 to your specific media
- 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

Please click here for the ABC heat exchanger advantages in Chinese Our state-of-the-art fabrication technology uses high-pressure hydraulic expansion to seal the tube-to-tube sheet joints. This reduces the risk of roller expansion damage, as well as work-hardening effects and excessive thinning of the tubing. In addition, our proprietary integrated double tube design virtually eliminates the possibility of cross contamination. The result is consistent performance, reduced maintenance and extended equipment life.
Prior to shipment, every heat exchanger undergoes rigorous testing and comprehensive documentation procedures that can include:
