TEMA Type BEW or AEW (OR)
Construction
Available in TEMA B, C, or R construction- Removable bundle
- straight tube
- full floating head with double O-ring seal
Applications:
Recommended for:
- Oil
- Water
- Air
- Nitrogen
- Dry Carbon Dioxide
- Other inert gases
Should not be used for:
- Hydrocarbon gases
- Hydrogen
- Oxygen
- Lethal gases
- Gases with low molecular weights
- Volatile, toxic, or flammable fluids
Advantages:
- Tube bundle can be easily removed for cleaning shell side, repairing or replacing
- Straight tubes can be easily cleaned
- Double O-ring seal allows tube bundle to expand and contract freely
Prevents intermixing of shell and tube side fluids.- Telltale holes are provided in the O-ring retainer for leak detection
- Most cost-effective floating head type construction.
- All gasketed joints are exposed for easy observation of leaks.
Limitations:
- Maximum number of tube passes is two
- Fluid intermixing is possible in the event of an O-ring failure
- Maximum temperatures are limited
