A Simple Guide to Understanding TEMA configurations
TEMA Types
Shell-and-tube heat exchangers are commonly identified by a three-letter TEMA designation. These letters describe the front-end "stationary" head, shell type and rear-end head construction. Understanding the TEMA designation can help you identify how an exchanger is built, how it can be maintained and what applications it may be best suited for.
Example: BEM
a bonnet-style front head (B), one pass shell (E) and fixed tubesheet rear head (M) is one of the most common and widely used configurations. B + M + M = BEM
| TEMA Class | Typical Service | |

| B | Chemical process service | |
| C | Commercial and general process applications | |
| R | Refinery and petroleum process applications |
