TEMA Type BEP or AEP
Construction:
Available in TEMA B, C, or R construction- Removable bundle.
- Straight tube
- Skirt type packed floating tubesheet
Applications:
Recommended for:
- Hydrogen
- Oxygen
- Air
- Nitrogen
- Hydrocarbon gases
- Gases with low molecular weights
Advantages:
Floating end allows for differential thermal expansion between the shell side and tube side, eliminating the need for a costly expansion joint- Well-suited to higher pressure, gas in the tube units, and low molecular weight gas units
- Intermixing of shell and tube fluids is unlikely
- Provides maximum heat transfer surface and high thermal efficiency.
- Multi-pass tube side designs are available
- Straight tubes can be easily cleaned
- Tube bundle can be easily removed for cleaning shell side, repairing or replacing.
Limitations:
- >Maximum shell side design pressures are generally limited to 150 PSIG
- Gases, except for low pressure air and nitrogen, should be kept on the tube side
