TEMA Type BEU or AEU
Construction:
Removable bundle- U-tube
- Full floating bundle
- ASME and TEMA "B", "C" or "R" construction
Application:
- Recommended for gas & liquid services.
- For oil and other viscous fluid heaters with steam on the tube side.
Advantages:
- No packed joint to leak and contaminate fluid
- Gasketed joints are minimized
- Provides multi-pass tube designs
- U-bends allow for differential thermal expansion
- Less costly than packed floating head or floating head designs, especially for higher tube side pressured since there is only one tubesheet, shell flange and head
Limitations:
- Should be avoided where the tube side fluid is dirty or fouling since tubes can only be cleaned by chemical means.
- True counter-current flow cannot be obtained since single pass on the tubeside is not possible.
- Cannot be used where a temperature cross exists.
